Commander '''Xaviar''' (ZUH-vee-ahr) is a [[Colonial Warrior]]<ref>Xaviar is seen wearing a blue [[Warrior]]'s [[Uniforms (TOS)#Blue Officer uniform|tunic with cape]] in the first two installments of "[[Galactica Discovers Earth]]". Additionally, he is called "commander" by Adama (despite not having pins on his collar) and has experience in flying [[Viper (1980)|Viper]]s, lending to the likely assumption that he is a Colonial Warrior who is also on the Council. This is not without precedent, as Adama is in a similar relationship for both the [[Original Series]] and ''1980''. </ref> and member of the [[Quorum of Twelve (TOS)|Council of Twelve]] during the time where [[The Fleet (TOS)|the Fleet]] has found the [[Thirteenth Tribe (TOS)|lost colony]] of [[Earth (1980)|Earth]].

Believing himself to be a great leader, Xaviar differs with Commander [[Adama (1980)|Adama]] on how to best bring Earth's technology up to the level of the Colonials. He believes that by using the [[time warp synthesizer]] technology developed by Doctor [[Zee]], he can lead a team back into time to advance Earth's technological development from the past, so that Earth is capable of defending the Galactican Fleet in 1980 A.D. After failing to solicit Adama's support for his plan, who obliquely rebukes Xaviar from even presenting his plan to the Council for a vote, he takes matters into his own hands and goes back in time to try to alter history and accelerate Earth's technological development by himself.

Xaviar goes back to Nazi Germany to try to introduce advanced weapons technology to the Germans via their V-2 rocket program, which is thwarted by [[Troy (1980)|Troy]], [[Dillon]] and [[Jamie Hamilton]], who pursue him into 1944. After successfully evading the trio, he returns to 1980 and attempts to co-opt Professor [[Donald Mortinson]], a nuclear physicist contacted by Troy and Dillon, to participate in his time travel plan.

The storyline implies that Xaviar also goes back to Revolution-era America to attempt to change history there, a scheme that also fails thanks to Dillon, Troy and Hamilton ([[1980]]: "[[Galactica Discovers Earth, Part I|Galactica Discovers Earth]]").

Xaviar later returns to the present time frame in a plot to try to ransom [[Galactica (TOS)|''Galactica'']]'s [[Super Scouts|children]] in an attempt to secure his freedom. Using a process known as [[epidermal transformation]], he takes the form of Lieutenant [[Nash]] and convinces Troy and Dillon to take a booby-trapped Viper in pursuit of Xaviar as allegedly ordered by Adama. After they are out of the way, he tries to take the Super Scouts and Hamilton hostage after a baseball game, but is thwarted by Troy and Dillon. Although he escapes, he shoots Colonel [[Jack Sydell]] ([[1980]]: "[[Spaceball]]") which lands him in the hospital in a coma-like condition ([[1980]]: "[[The Night the Cylons Landed, Part I]]").

== In the unproduced scripts ==

In two unproduced scripts, "[[The Wheel of Fire]]" and "[[The Day They Kidnapped Cleopatra]]", Xaviar makes a reappearance and is the antagonist in both, as is to be expected.

In "The Day They Kidnapped Cleopatra", a script that was being shot at the time ''[[Galactica 1980]]'''s cancellation order is handed down by ABC, Xaviar travels to [[w:48 BC|48 BC]] and attempts to change Earth's history from [[w:Egypt|Egypt]] by convincing [[Cleopatra]] that he is a god, via the use of his invisibility field. After Cleopatra has his drink poisoned with asp venom so as to prove that he's indeed a god, Xaviar makes a fearful flight to 1980 AD to solicit the help of Troy, Dillon, and Jamie Hamilton, bringing Cleopatra along with him.

After the poison is neutralized by 1980 Earth's medicines, he escapes the Warriors and, with Cleopatra, returns to 48 BC. Troy, Dillon and Hamilton pursue him and thwart his plan to take over Cleopatra's kingdom, which fell some 18 years after, as stated in Earth's history.

In an episode that was written as a sequel to "[[The Return of Starbuck]]", Xaviar returns to 1980 and is pursued by a squadron of Vipers. During the pursuit, a phalanx of Cylon [[Raider (TOS)|Raider]]s interfere and attempt to capture Xaviar, desiring to know why the Colonials are pursuing one of their own. Xaviar escapes back through time, but drags a Raider back to [[w:592 BC|592 BC]]. With Troy (who is sent back by [[Starbuck (1980)|Starbuck]], now a [[Being of Light]]), they destroy the Raider before it can do any damage to Earth's past, and Xaviar evades capture.

== Novelization depiction ==

{{separate continuity|universe=1980|type=line}}

In the [[Galactica Discovers Earth (Book)|novelization]] by [[Michael Resnick]], Xaviar is described as having gray eyes, and is both a warrior and a scientist.<ref>{{cite_book|last=Resnick|first=Michael|authorlink=Michael Resnick|authorlinkurl=|year=1981|title=[[Battlestar Galactica 5: Galactica Discovers Earth]]|publisher=Berkley Books|location=|id=|pages=129, 138}}</ref>.

==Notes==

* Xaviar is played by a different actor in "Spaceball", which is explained to be a kind of disguise that made him appear like Colonial pilot Lt. [[Nash (1980)|Nash]].
* The most common misspelling of Xaviar is Xavier. However, the scripts for "[[The Day They Kidnapped Cleopatra]]" and "[[The Wheel of Fire]]" both spell the name as "Xaviar". This is further supported by on screen pronunciations of Xaviar's name as ZUH-vee-ahr (similar to "caviar") in "[[Galactica Discovers Earth, Part I]]" by [[Dillon]] and others. Since these sources are superior in their association with the series from a behind-the-scenes standpoint, this is the spelling that is employed on Battlestar Wiki.

Cylon War-era Centurion

2012-12-18T22:03:35Z

Graf Iblis:

[[Image:Cent 005.jpg|thumb|thumb|Cylon Centurion during the First Cylon War.]]

'''Cylon War-era Centurion''' is an umbrella term describing a range of [[Cylons (RDM)|Cylon]] forms encountered during the [[Cylon War]]. They are the next evolutionary step following the prototypical [[U-87 Cyber Combat Unit]] and the predecessors to (and creators of) the [[Humanoid Cylon|humanoid Cylon]] form.

==History==
The Cylon War-era Centurions (henceforth referred to as "Centurions") are the next evolutionary step - or modification - of existing Cylon models created by [[Graystone Industries]] of [[Caprica City]] ([[CAP]]: [[Caprica pilot|Pilot]], "[[Apotheosis (episode)|Apotheosis]]"). Resembling the prototypical [[U-87 Cyber Combat Unit]] chassis, Centurions are distinguished by their iconic chrome armor and sometimes likened to "walking chrome toasters" ([[TRS]]: [[Miniseries]], "[[Razor]]").

[[Image:Galactica Museum, "Daybreak, Part II".jpg|thumb|left|The armor of a Centurion in ''Galactica'''s museum.]]

Appearing in the years during which [[robot]]s are used by humanity to make life easier on the [[Twelve Colonies of Kobol|Twelve Colonies]], Centurions are closely related to the Cylons provided by Graystone Industries to the Caprican Ministry of Defense for use as simple soldiers ([[CAP]]: [[Caprica pilot|Pilot]], "[[Unvanquished]]").

Not long after their introduction to Colonial society as cannon fodder and laborers, the Cylons develop their own culture and religion worshiping the monotheistic [[God (RDM)|God]] followed by some humans aligned with the [[Soldiers of the One]] cult. Shortly thereafter, the Cylons inexplicably turn on their human masters, initiating the conflict known as the [[Cylon War]] ([[CAP]]: "[[Apotheosis (episode)|Apotheosis]]"). Alongside other Cylon models - including the military and [[Civilian Cylon|commercial]] types - the Centurions become a mainstay in the Cylons' war against humanity ([[TRS]]: "[[Razor]]", ''[[Blood and Chrome]]'').

===War with Humanity===
The Cylon War is staged in various theaters including [[Caprica (RDM)|Caprica]] and [[Tauron (RDM)|Tauron]] and other outlying Colonial [[Ice planet|world]]s. Centurions are present at these locations, fighting hand to hand against the Colonial Military and civilian fighters, as well as piloting [[Raider (RDM)#Cylon War-era raider|Raider]]s and commanding [[Basestar (RDM)#Cylon War-era basestar|basestar]]s in battle against the [[Colonial Fleet (RDM)|Colonial Fleet]] in space ([[TRS]]: "[[Razor]]", ''[[Blood and Chrome]]'').

[[Image:Cylon Centurions on Tuaron, "Razor".jpg|thumb|Centurions fire weapons on Tauron during the Cylon War.]]

Despite maintaining troops on Colonial worlds, the Cylons establish their own territory adjacent to Colonial space but frequently attack human targets (''[[Blood and Chrome]]'').

During their fight with humanity, the Centurions also begin conducting experiments on prisoners. Performing brutal operations on live victims, the Centurions strive to create fully biological [[humanoid Cylon]]s. Their experiments result in the development of the [[Hybrid]]s - an evolutionary "dead end" - the [[First Hybrid|first]] of which is created shortly before the cessation of hostilities ([[TRS]]: "[[Razor]]").

Unable to create organic life that can survive without technology, the Centurions agree to end the war in exchange for help from the [[Final Five]] – survivors of the [[Earth (RDM)|Thirteenth Colony]] who possess [[Resurrection (RDM)|resurrection technology]]. The Centurions sign the [[Cimtar (RDM)|Cimtar Peace Accord]] with humanity and withdraw to their territory with The Five. Located somewhere beyond the designated [[Armistice Line]], the Centurions and Final Five construct [[The Colony]] where they develop eight humanoid models, instilling in them monotheistic beliefs ([[TRS]]: "[[No Exit]]", "[[The Plan]]").

===The Guardians===
[[Image:Centurion pair.jpg|thumb|Guardian Cylons protect their Hybrid.]]

The Guardians are a group of Cylon-War era Centurions that pilot a [[Guardian basestar|single basestar]], containing the first Cylon Hybrid, into deep space following the Armistice. Utilizing decades old Raiders and weaponry, the Guardians operate separately from the rest of the Cylon civilization, becoming something of a Cylon legend.

These Centurions guard the original Hybrid, still alive over 40 years after its creation. Seeking to further their evolution and continue the experiments begun during the first Cylon War, the Guardians capture a civilian science team from the surviving [[The Fleet (RDM)|Fleet]] following the Fall of the Twelve Colonies. This triggers a [[Battle of the Guardian basestar|battle]] between the Guardian baseship and the [[Pegasus (RDM)|battlestar ''Pegasus'']], under the command of [[Lee Adama]]. During the battle, an assault team led by Major [[Kendra Shaw]] boards the basestar and rescues the science team, detonating a [[Weapons in the Re-imagined Series#Nuclear weapons|nuclear weapon]] that destroys the ship and kills the Hybrid ([[TRS]]: "[[Razor]]").

=== The Colony ===
[[Image:Centurions vs. Centurions, "Daybreak, Part II".jpg|thumb|right|Cylon War-era models battle modern Centurions.]]

Despite the development of the [[Cylon Centurion|Modern Centurion]] by the humanoid Cylons, some of the original Centurions remain in operation aboard the Cylon Colony. Serving alongside their modern counterparts, these Centurions are instrumental during the [[Battle of the Colony]], when remaining Colonial forces launch an all out offensive to retrieve the half-Cylon, half-Human child [[Hera Agathon|Hera]].

Armed with advanced weaponry, these Centurions engage in combat against rebel Cylon Centurions, dubbed "Red Stripes" by the crew of ''[[Galactica (RDM)|Galactica]]''. The Centurions also act as shock troops, boarding the ''Galactica'' at platoon strength. Ultimately, though, the Cylon boarding parties are repelled and the remaining Centurions are presumably destroyed when the Colony itself is knocked into a black hole ([[TRS]]: [[Miniseries]], "[[Daybreak, Part II]]").

==Design==
[[Image:Cylon War-era Raider cockpit, "Razor".jpg|thumb|left|Centurions (including a gold-colored variation) pilot a Cylon War-era Raider.]]

Likened to "walking chrome toasters" by the Colonials, the Cylon War-era Centurions still had their place in Cylon society far past the initial conflict. Iconic features such as the red, pulsating "eye" were carried into later generations of the Cylon Centurion and even into the modern, autonomous [[Raider (RDM)|Raider]]s ([[Miniseries]]). Still many of these models were scrapped before the second Cylon attack on the Colonies ([[Razor]]).

The Cylon War-era Centurions were, like their predecessors, bipedal [[w:android|androids]], with an average height of 6'6"<ref name="armistice"/> and covered in silver-chrome plating. They carried backpack-like power cells and were protected by flexible rear armor which covers otherwise exposed internal mechanisms <ref>[[Adam "Mojo" Lebowitz]]: [http://darthmojo.wordpress.com/2008/05/12/bsg-vfx-anatomy-of-a-cylon/ Anatomy of a Cylon]</ref>. Physically stronger than humans, the Centurions were designed with sufficient dexterity and capability of using weapons and tools. Centurions communicated at least partially vocally, but were also capable of receiving radio signals internally ([[Razor]]).

Unlike their successors, these early Centurions did not possess built-in projectile weapons, but were armed with retractable blades, built into their forearms. There are indications that Centurions also used bladed weapons such as swords in at least some Cylon War conflicts<ref>In the [[Miniseries]], two children can be seen wearing Centurion masks and waving swords while at play. Additionally, [[William Adama]] has a [[Monclair]] painting depicting a battle in the Cylon War, in which swords are used by Centurions, in addition to a sword directly underneath. This may be a replica or an actual sword from the war.</ref>.)

===Variations===
[[Image:Cylon War-era Centurion fires weapon, "Daybreak, Part II".jpg|thumb|A Centurion warrior fires a weapon aboard ''Galactica''.]]

There are at least four variations of the Cylon War-era Centurion based upon function and placement within the hierarchy of early Cylon society. In addition to standard Centurion models, more compact "Warrior" versions and sturdier "Soldiers" have been observed. Centurion warriors were distinguished by more helmet-like heads and were heavily armored, possessing flexible coverings over the torso and upper arms and ammunition clips around their waists. These warrior versions were used in great numbers to defend the Colony during the final days of the second conflict. Gold-colored Centurions were also in service during the Cylon War, observed commanding Cylon raiders in combat.

===Demeanor===
[[Image:Razor Flashback 4.jpg|thumb|left|A Centurion aiming its gun in free fall.]]

The Colonial-designed Centurions used [[Silica pathways|artificial intelligence]], and were designed as sentient beings.<ref>[[William Adama]] and [[Sharon Agathon]] confirm this point in season 3 episodes that explain why the advanced successors to the war-era models are not sentient: To prevent an intra-Cylon uprising between the [[humanoid Cylon]]s and their creations.</ref> By the time the first war ended, they were already practitioners of a religion centered around what would come to be considered the "Cylon God" ([[No Exit]]).

[[Saul Tigh]], who possessed false memories of the First Cylon War, recalled the Cylon boarding of the ''[[Brenik]]'', and the apparent hatred the Centurions had for humanity - despite the physical inability of the Cylons to show emotion on their faces (deleted scene from "[[Scattered]]"). This reflection of animosity and intensity is also apparent in the stylized [[Monclair]] painting in [[William Adama]]'s quarters, depicting Cylon War-era Centurions battling Colonial forced utilizing relatively primitive weapons ([[Islanded In a Stream of Stars ]]).

== Connection to the Original Series ==
[[Image:Cylon_centurion_model_0005.jpg|thumb|[[Armistice Officer]]'s paper work on the original Cylon Centurion model. ([[Miniseries]])]]

The readable text of the [[Armistice Officer|Armistice Officer's]] Cylon Specifications sheet shows:

:'' <center><b>CYLON SPECIFICATIONS</b></center>''
:'' <center><b>Cylon Centurian </b><ref>There is some debate among fans regarding the canonical spelling of this model's name. [[Wikipedia:Centurion]]s were professional officers of the Roman Army, and are widely acknowledged as the basis of the Cylon name. Some official material, such as the on-screen appearance of the Armistice Officer's datasheet and the packaging of the original Mattel action figures, used the spelling "Centurian." For the purposes of this wiki, the spelling "Centurion" is used throughout.</ref>[sic]<b> Model 0005</b></center>''
: ''<b>The Cylon:</b>

<blockquote>''A Cylon is a bipedal robot. They are self-aware, and usually quite logical. They are not especially fast, but they are quite strong. They are artificial in nature, and are larger than a human, around 6' 6" (2m), although this varies with their type. Cylon eyes glow red, and pulse back and forth. A Cylon is powered by internal powercells which allow it to function without outside aid for around nine to ten [[yahren]]s.<ref>A [[Continuity errors (RDM)|continuity error or gaffe]] appears in the Armistice Officer's documents with the use of the word "yahren" (an Original Series measure of a year).</ref>''</blockquote>

==Notes==
[[Image:Centuion Display.jpg|thumb|Original series Cylon armor on display in the ''Galactica'' museum during the Miniseries.]]
*Centurions in "[[Razor]]" and the [[Razor Flashbacks]] move with greater agility and speed than their Original Series counterparts, and utilize [[Weapons in the Re-imagined Series#Handheld weapons|projectile weapon]]s instead of a [[laser pistol]] or [[laser rifle]].

*A built-in switchblade knife is part of the left hand/forearm. The blade is approximately 8 inches long and is used in close combat ([[Razor Flashbacks]]).

*In a scene in the [[Miniseries]], some children can be seen running around in costumes which are patterned after this model.

*The typical catchphrase of the Cylons in both series is the iconic statement "[[By your command]]."

==Behind the scenes==
The Centurion models for "[[Razor]]" were designed by [[Pierre Drolet]], who had, among other things, previously designed the [[Viper Mark II]], which is also a homage to the Original Series. Drolet said: "I always thought it was a great design. My goal was not to redesign it from scratch, but to work with the original and make subtle additions."

The armor of a Cylon Centurion from the Original Series can be seen in the museum aboard ''Galactica'' during the Miniseries. This is later retconned in "Daybreak, Part II" to reflect the redesigned Centurion from "Razor". Still, this redesigned museum version possesses some details carried over from the original design not present in the "living" Centurions.

Canon is only that 0005 is some kind of designation associated with the design displayed on the specification sheet, but we don't know that the number means "every model that sort of looks like the oBSG Cylon, regardless of how many smaller or larger changes are made by the VFX people". That would be fanfic, which is why I asked for that article to be renamed. For all we know, "Razor" might've featured 0007 and 0008, "Blood & Chrome" 0003 and so forth. That is why the number shouldn't be used unless we're discussing the specification sheet from the miniseries. --[[User:Graf Iblis|Graf Iblis]] 16:46, 18 December 2012 (EST)

Cylon War-era Centurion

2012-12-18T21:30:56Z

Graf Iblis: Incorrectly implies that "Centurion" mostly refers to war-era models

[[Image:Cent 005.jpg|thumb|thumb|Cylon Centurion during the First Cylon War.]]

The '''Cylon War-era Centurion''' is the quintessential [[Cylons (RDM)|Cylon]] form during the [[Cylon War]]. They are the next evolutionary step following the prototypical [[U-87 Cyber Combat Unit]] and the predecessors to (and creators of) the [[Humanoid Cylon|humanoid Cylon]] form.

==History==
The Cylon War-era Centurions (henceforth referred to as "Centurions") are the next evolutionary step - or modification - of existing Cylon models created by [[Graystone Industries]] of [[Caprica City]] ([[CAP]]: [[Caprica pilot|Pilot]], "[[Apotheosis (episode)|Apotheosis]]"). Resembling the prototypical [[U-87 Cyber Combat Unit]] chassis, Centurions are distinguished by their iconic chrome armor and sometimes likened to "walking chrome toasters" ([[TRS]]: [[Miniseries]], "[[Razor]]").

[[Image:Galactica Museum, "Daybreak, Part II".jpg|thumb|left|The armor of a Centurion in ''Galactica'''s museum.]]

Appearing in the years during which [[robot]]s are used by humanity to make life easier on the [[Twelve Colonies of Kobol|Twelve Colonies]], Centurions are closely related to the Cylons provided by Graystone Industries to the Caprican Ministry of Defense for use as simple soldiers ([[CAP]]: [[Caprica pilot|Pilot]], "[[Unvanquished]]").

Not long after their introduction to Colonial society as cannon fodder and laborers, the Cylons develop their own culture and religion worshiping the monotheistic [[God (RDM)|God]] followed by some humans aligned with the [[Soldiers of the One]] cult. Shortly thereafter, the Cylons inexplicably turn on their human masters, initiating the conflict known as the [[Cylon War]] ([[CAP]]: "[[Apotheosis (episode)|Apotheosis]]"). Alongside other Cylon models - including the military and [[Civilian Cylon|commercial]] types - the Centurions become a mainstay in the Cylons' war against humanity ([[TRS]]: "[[Razor]]", ''[[Blood and Chrome]]'').

===War with Humanity===
The Cylon War is staged in various theaters including [[Caprica (RDM)|Caprica]] and [[Tauron (RDM)|Tauron]] and other outlying Colonial [[Ice planet|world]]s. Centurions are present at these locations, fighting hand to hand against the Colonial Military and civilian fighters, as well as piloting [[Raider (RDM)#Cylon War-era raider|Raider]]s and commanding [[Basestar (RDM)#Cylon War-era basestar|basestar]]s in battle against the [[Colonial Fleet (RDM)|Colonial Fleet]] in space ([[TRS]]: "[[Razor]]", ''[[Blood and Chrome]]'').

[[Image:Cylon Centurions on Tuaron, "Razor".jpg|thumb|Centurions fire weapons on Tauron during the Cylon War.]]

Despite maintaining troops on Colonial worlds, the Cylons establish their own territory adjacent to Colonial space but frequently attack human targets (''[[Blood and Chrome]]'').

During their fight with humanity, the Centurions also begin conducting experiments on prisoners. Performing brutal operations on live victims, the Centurions strive to create fully biological [[humanoid Cylon]]s. Their experiments result in the development of the [[Hybrid]]s - an evolutionary "dead end" - the [[First Hybrid|first]] of which is created shortly before the cessation of hostilities ([[TRS]]: "[[Razor]]").

Unable to create organic life that can survive without technology, the Centurions agree to end the war in exchange for help from the [[Final Five]] – survivors of the [[Earth (RDM)|Thirteenth Colony]] who possess [[Resurrection (RDM)|resurrection technology]]. The Centurions sign the [[Cimtar (RDM)|Cimtar Peace Accord]] with humanity and withdraw to their territory with The Five. Located somewhere beyond the designated [[Armistice Line]], the Centurions and Final Five construct [[The Colony]] where they develop eight humanoid models, instilling in them monotheistic beliefs ([[TRS]]: "[[No Exit]]", "[[The Plan]]").

===The Guardians===
[[Image:Centurion pair.jpg|thumb|Guardian Cylons protect their Hybrid.]]

The Guardians are a group of Cylon-War era Centurions that pilot a [[Guardian basestar|single basestar]], containing the first Cylon Hybrid, into deep space following the Armistice. Utilizing decades old Raiders and weaponry, the Guardians operate separately from the rest of the Cylon civilization, becoming something of a Cylon legend.

These Centurions guard the original Hybrid, still alive over 40 years after its creation. Seeking to further their evolution and continue the experiments begun during the first Cylon War, the Guardians capture a civilian science team from the surviving [[The Fleet (RDM)|Fleet]] following the Fall of the Twelve Colonies. This triggers a [[Battle of the Guardian basestar|battle]] between the Guardian baseship and the [[Pegasus (RDM)|battlestar ''Pegasus'']], under the command of [[Lee Adama]]. During the battle, an assault team led by Major [[Kendra Shaw]] boards the basestar and rescues the science team, detonating a [[Weapons in the Re-imagined Series#Nuclear weapons|nuclear weapon]] that destroys the ship and kills the Hybrid ([[TRS]]: "[[Razor]]").

=== The Colony ===
[[Image:Centurions vs. Centurions, "Daybreak, Part II".jpg|thumb|right|Cylon War-era models battle modern Centurions.]]

Despite the development of the [[Cylon Centurion|Modern Centurion]] by the humanoid Cylons, some of the original Centurions remain in operation aboard the Cylon Colony. Serving alongside their modern counterparts, these Centurions are instrumental during the [[Battle of the Colony]], when remaining Colonial forces launch an all out offensive to retrieve the half-Cylon, half-Human child [[Hera Agathon|Hera]].

Armed with advanced weaponry, these Centurions engage in combat against rebel Cylon Centurions, dubbed "Red Stripes" by the crew of ''[[Galactica (RDM)|Galactica]]''. The Centurions also act as shock troops, boarding the ''Galactica'' at platoon strength. Ultimately, though, the Cylon boarding parties are repelled and the remaining Centurions are presumably destroyed when the Colony itself is knocked into a black hole ([[TRS]]: [[Miniseries]], "[[Daybreak, Part II]]").

==Design==
[[Image:Cylon War-era Raider cockpit, "Razor".jpg|thumb|left|Centurions (including a gold-colored variation) pilot a Cylon War-era Raider.]]

Likened to "walking chrome toasters" by the Colonials, the Cylon War-era Centurions still had their place in Cylon society far past the initial conflict. Iconic features such as the red, pulsating "eye" were carried into later generations of the Cylon Centurion and even into the modern, autonomous [[Raider (RDM)|Raider]]s ([[Miniseries]]). Still many of these models were scrapped before the second Cylon attack on the Colonies ([[Razor]]).

The Cylon War-era Centurions were, like their predecessors, bipedal [[w:android|androids]], with an average height of 6'6"<ref name="armistice"/> and covered in silver-chrome plating. They carried backpack-like power cells and were protected by flexible rear armor which covers otherwise exposed internal mechanisms <ref>[[Adam "Mojo" Lebowitz]]: [http://darthmojo.wordpress.com/2008/05/12/bsg-vfx-anatomy-of-a-cylon/ Anatomy of a Cylon]</ref>. Physically stronger than humans, the Centurions were designed with sufficient dexterity and capability of using weapons and tools. Centurions communicated at least partially vocally, but were also capable of receiving radio signals internally ([[Razor]]).

Unlike their successors, these early Centurions did not possess built-in projectile weapons, but were armed with retractable blades, built into their forearms. There are indications that Centurions also used bladed weapons such as swords in at least some Cylon War conflicts<ref>In the [[Miniseries]], two children can be seen wearing Centurion masks and waving swords while at play. Additionally, [[William Adama]] has a [[Monclair]] painting depicting a battle in the Cylon War, in which swords are used by Centurions, in addition to a sword directly underneath. This may be a replica or an actual sword from the war.</ref>.)

===Variations===
[[Image:Cylon War-era Centurion fires weapon, "Daybreak, Part II".jpg|thumb|A Centurion warrior fires a weapon aboard ''Galactica''.]]

There are at least four variations of the Cylon War-era Centurion based upon function and placement within the hierarchy of early Cylon society. In addition to standard Centurion models, more compact "Warrior" versions and sturdier "Soldiers" have been observed. Centurion warriors were distinguished by more helmet-like heads and were heavily armored, possessing flexible coverings over the torso and upper arms and ammunition clips around their waists. These warrior versions were used in great numbers to defend the Colony during the final days of the second conflict. Gold-colored Centurions were also in service during the Cylon War, observed commanding Cylon raiders in combat.

===Demeanor===
[[Image:Razor Flashback 4.jpg|thumb|left|A Centurion aiming its gun in free fall.]]

The Colonial-designed Centurions used [[Silica pathways|artificial intelligence]], and were designed as sentient beings.<ref>[[William Adama]] and [[Sharon Agathon]] confirm this point in season 3 episodes that explain why the advanced successors to the war-era models are not sentient: To prevent an intra-Cylon uprising between the [[humanoid Cylon]]s and their creations.</ref> By the time the first war ended, they were already practitioners of a religion centered around what would come to be considered the "Cylon God" ([[No Exit]]).

[[Saul Tigh]], who possessed false memories of the First Cylon War, recalled the Cylon boarding of the ''[[Brenik]]'', and the apparent hatred the Centurions had for humanity - despite the physical inability of the Cylons to show emotion on their faces (deleted scene from "[[Scattered]]"). This reflection of animosity and intensity is also apparent in the stylized [[Monclair]] painting in [[William Adama]]'s quarters, depicting Cylon War-era Centurions battling Colonial forced utilizing relatively primitive weapons ([[Islanded In a Stream of Stars ]]).

== Connection to the Original Series ==
[[Image:Cylon_centurion_model_0005.jpg|thumb|[[Armistice Officer]]'s paper work on the original Cylon Centurion model. ([[Miniseries]])]]

The readable text of the [[Armistice Officer|Armistice Officer's]] Cylon Specifications sheet shows:

:'' <center><b>CYLON SPECIFICATIONS</b></center>''
:'' <center><b>Cylon Centurian </b><ref>There is some debate among fans regarding the canonical spelling of this model's name.

For the purposes of this wiki, the spelling "Centurion" is used throughout.</ref>[sic]<b> Model 0005</b></center>''
: ''<b>The Cylon:</b>

<blockquote>''A Cylon is a bipedal robot. They are self-aware, and usually quite logical. They are not especially fast, but they are quite strong.

==Notes==
[[Image:Centuion Display.jpg|thumb|Original series Cylon armor on display in the ''Galactica'' museum during the Miniseries.]]
*Centurions in "[[Razor]]" and the [[Razor Flashbacks]] move with greater agility and speed than their Original Series counterparts, and utilize [[Weapons in the Re-imagined Series#Handheld weapons|projectile weapon]]s instead of a [[laser pistol]] or [[laser rifle]].

*A built-in switchblade knife is part of the left hand/forearm. The blade is approximately 8 inches long and is used in close combat ([[Razor Flashbacks]]).

*In a scene in the [[Miniseries]], some children can be seen running around in costumes which are patterned after this model.

*The typical catchphrase of the Cylons in both series is the iconic statement "[[By your command]]."

==Behind the scenes==
The Centurion models for "[[Razor]]" were designed by [[Pierre Drolet]], who had, among other things, previously designed the [[Viper Mark II]], which is also a homage to the Original Series. Drolet said: "I always thought it was a great design. My goal was not to redesign it from scratch, but to work with the original and make subtle additions."

The armor of a Cylon Centurion from the Original Series can be seen in the museum aboard ''Galactica'' during the Miniseries. This is later retconned in "Daybreak, Part II" to reflect the redesigned Centurion from "Razor". Still, this redesigned museum version possesses some details carried over from the original design not present in the "living" Centurions.

Cylon War-era Centurion

Colonial calendar

2012-12-08T22:19:03Z

Graf Iblis:

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

A hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of terms such as "day", "month" or "year", there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method, as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the ''Caprica'' series and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers eventually worked out a method which is based on the Roman calendar. Dates in that style were also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which therefore revealed much of the basic calendar structure. However, since the series rarely took us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this would have taken him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Building upon the units described above, ''Caprica'' introduced its own system which is relatively consistent and widely used on various props.

=== Years ===

Recent years are two-digit numbers, almost always preceded by the letters YR. Several common formats are listed below:

*YR01
*YR 01
*yr01
*01YR

Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42. Years before YR0x are expressed as [[Colonial calendar#Here Be Dragons|YR9x]], while [[Colonial calendar#Unknown episodes|ancient dates]] can be longer than two digits and designated "byr". [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]."

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January
|-
| Februarius || [[The Caprican#Februarius|at least 27]] || February
|-
| Martius || [[The Caprican#Martius|at least 30]] || March
|-
| Aprilis || [[The Caprican#Aprilis|at least 24]] || April
|-
| Maius || [[Colonial calendar#Pyramid posters|at least 27]] || May
|-
| Iunius || [[Colonial calendar#Pyramid posters|at least 27]] || June
|-

|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || [[Colonial calendar#Unknown episodes|at least 26?]] || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).
[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Guides to artifacts dated at around "400 byr".]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica Museum Of Contemporary Art Poster Set.jpg|x20px]]

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week" ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]
*''The Caprican Comic Pages'' read by [[William "Willie" Adama]] are dated "JUNE 22, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Willies Funny Papers.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx]).
*Sam Adama ("Ross Bailey Framo") was born on Iunius 11, YR92 according to his falsified birth certificate. However, Framo's driver's license appears to give his date of birth as 08-11-? as opposed to 06-11-92YR. The 08 might be a leftover from Joseph's falsified driver's license ([http://caprica.propworx.com Propworx]). [[Image:Caprica Sams Caprican Passport and ID.jpg|x20px]]

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Gemenon Twins]] game are dated "IUNIUS 10, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Pyramid Buccaneers Tickets.jpg|x20px]]

====Unknown episodes====

*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The "FILE DATE" on [[Mar-Beth Willow]]'s GDD file is "12/26/yr42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Mar-Beth GDD Hero File.jpg|x20px]]

====Pyramid posters====

The [http://web.archive.org/web/20101011165818/http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html Profiles in History auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2012-12-08T22:00:58Z

Graf Iblis: /* The Calendar from Caprica */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

A hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of terms such as "day", "month" or "year", there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the ''Caprica'' series and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely took us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this would have taken him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Building upon the units described above, ''Caprica'' introduced its own system which is relatively
consistent and widely used on various props.

=== Years ===

Recent years are two-digit numbers, almost always preceded by the letters YR. Several common formats are listed below:

*YR01
*YR 01
*yr01
*01YR

Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42. Years before YR0x are expressed as [[Colonial calendar#Here Be Dragons|YR9x]], while [[Colonial calendar#Unknown episodes|ancient dates]] can be longer than two digits and designated "byr". [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]."

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).
[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Guides to artifacts dated at around "400 byr".]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica Museum Of Contemporary Art Poster Set.jpg|x20px]]

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week" ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]
*''The Caprican Comic Pages'' read by [[William "Willie" Adama]] are dated "JUNE 22, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Willies Funny Papers.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx]).
*Sam Adama ("Ross Bailey Framo") was born on Iunius 11, YR92 according to his falsified birth certificate. However, Framo's driver's license appears to give his date of birth as 08-11-? as opposed to 06-11-92YR. The 08 might be a leftover from Joseph's falsified driver's license ([http://caprica.propworx.com Propworx]). [[Image:Caprica Sams Caprican Passport and ID.jpg|x20px]]

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Gemenon Twins]] game are dated "IUNIUS 10, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Pyramid Buccaneers Tickets.jpg|x20px]]

====Unknown episodes====

*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The "FILE DATE" on [[Mar-Beth Willow]]'s GDD file is "12/26/yr42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Mar-Beth GDD Hero File.jpg|x20px]]

====Pyramid posters====

The [http://web.archive.org/web/20101011165818/http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html Profiles in History auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

'''Evelyn''' was [[Joseph Adama]]'s assistant and close friend in the years leading up to the [[First Cylon War]]. She was also the [[New Cap City]] persona known as '''Emmanuelle''', Adama's guide and partner in his search for the [[avatar]] of his deceased daughter, [[Tamara Adama]]. As time passes, she and Joseph Adama develop a relationship resulting in Joseph's second marriage.

After the death of [[William "Willie" Adama]], she marries Joseph, with whom they have a son, [[William Adama|William "Bill" Adama]], who is named after both his grandfather and deceased half-brother.

==History==

When Joseph Adama was in law school, Evelyn bought Joseph a cigarette lighter engraved with his name. The lighter was passed on to William, who considers it a good luck charm ([[TRS]]: "[[The Hand of God (RDM)|The Hand of God]]," [[CAP]]: "[[Dirteaters]]").

Evelyn worked for Joseph's [[Caprica (RDM)|Caprican]] law practice, acting as a personal assistant, associate and sometimes investigator for several years. Despite having been repeatedly promised that she would never have do it again, Evelyn grudgingly acted as secretary from time to time, delivering Adama coffee. Primarily, Evelyn arranged Adama's affairs, making sure drops were made to Caprican judges in return for judicial favors ([[CAP]]: "[[The Reins of a Waterfall]]," "[[Know Thy Enemy]]").

In addition to their close working relationship, Evelyn and Joseph shared a close personal relationship that bordered on the romantic ([[CAP]]: "[[The Reins of a Waterfall]]," "[[Know Thy Enemy]]").

Following the loss of his daughter [[Tamara Adama|Tamara]] in the [[Metropolitan Levitation Mass Transit|MagLev]] bombing, Evelyn watched helpless as Joseph descend further into mourning and become consumed with his search for Tamara's [[Tamara-A|avatar]] in the [[Virtual World]] construct known as [[New Cap City]] ([[CAP]]: "[[Caprica pilot|Pilot]]," "[[End of Line]]").

===Emmanuelle===
[[Image:Emmanuelle.jpg|thumb|"Emmanuelle" in New Cap City.]]
In order to intervene in Adama's growing obsession, Evelyn created a [[avatar|persona]] for herself that would allow her to keep watch over Joseph in New Cap City. Calling herself Emmanuelle, Evelyn chose a new physical appearance, and a harder, more streetwise identity ([[CAP]]: "[[The Imperfections of Memory]]).

Introducing herself as an associate of [[Tad Thorean|Tad "Herecles" Thorean]], "Emmanuelle" offered to act as Joseph's guide, helping him to search for Tamara's avatar. Helping Adama chose a better wardrobe in which to infiltrate New Cap City, Emmanuelle lead Joseph to the virtual nightclub ''Mysteries'' and introduced him to [[amp]], a performance-enhancing (though highly addictive) hack. Using amp, Joseph eliminates the crowd and guards at ''Mysteries'' in order to interrogate the owner, [[Cerberus]], as to the whereabouts of his daughter ([[CAP]]: "[[Ghosts in the Machine]]").

===End of Line===
[[Image:Evelyn and Joseph, 1x09.jpg|thumb|Evelyn comforts a grieving Joseph Adama.]]
Still coming up with few results, Evelyn as Emmanuelle continued to observe Joseph's downward spiral and his burgeoning addiction to amp. Realizing the search and her help were doing more harm than good, Emmanuelle devised a plan to lure the Tamara avatar to the New Cap City version of her [[Little Tauron]] apartment. There, Emmanuelle explained the damage that had been done to Tamara's father ([[CAP]]: "[[End of Line]]").

Leading Joseph to his apartment in New Cap City, Emmanuelle was present as Tamara-A shot herself in the chest, then turned the gun on her father - faking her own death and ejecting Joseph from the game ([[CAP]]: "[[End of Line]]").

In the real world, as Joseph reeled from losing his daughter all over again, Evelyn was there to comfort him ([[CAP]]: "[[End of Line]]").

===Life Goes On===
Following the apparently permanent loss of Tamara, Evelyn and Joseph began a romantic relationship. While she continued to keep his professional life running, Joseph's mother-in-law, [[Ruth]], believed that Evelyn was good for Adama's personal life and arranged for the two to have some time alone. As the two worked on paperwork relating to the recent [[Ha'la'tha]] alliance with [[Graystone Industries]], Evelyn and Joseph gave in to their passions and made love in Adama's apartment ([[CAP]]: "[[False Labor]]").

After the [[Guatrau]] discovers Sam and Joseph's efforts to smuggle [[U-87 Cyber Combat Unit]]s to the Tauron resistance, he orders them killed. After Ruth thwarts an assassination attempt by a Ha'la'tha soldier, Evelyn, Joseph, Sam and [[Willie Adama]] begin their flight into hiding. During an attempt to secure funds to do this from Sam's former place of business, they are intercepted by Ha'la'tha soldiers with orders to kill the Adama brothers. Feeling that they needed help, Willie impulsively dashes from the car to help, and Evelyn is unable to stop him. Willie's impulsive action results in his own death ([[CAP]]: "[[Here Be Dragons]]").

Within a year of the incident, Evelyn and Joseph marry and name their only son in memoriam of Joseph's first son and father: [[William Adama]] ([[CAP]]: "[[Apotheosis (episode)|Apotheosis]]").

==Notes==
* Evelyn's surname before marriage is never used.

* The character of "Evelyn" is quietly introduced in the ''[[Battlestar Galactica (TRS)|Battlestar Galactica]]'' episode "[[Hero]]." The name is derived from Admiral [[William Adama]]'s dossier prepared by [[Billy Keikeya]] prior to the decommissioning ceremony, and it gives his mother's name as "Evelyn" and her profession as accountant. This data appears in the [[Series bible#William Adama|Re-Imagined Series Bible.]]

* Evelyn had a brother who lived on Tauron and hunted foxes using dogs; her son William occasionally visited him in the summers. ([[CAP]]: "[[Here Be Dragons]]," [[TRS]]: "[[Sometimes a Great Notion]]")

* In an exclusive with the online fan publication ''The Caprica Times'', ''Caprica'' showrunner [[Kevin Murphy]] revealed that the character who became Evelyn was originally named Justine, and this name was used when Season 1.0 was filmed. After the writers decided that Willie Adama would be killed off, the Season 1.0 episodes in which she appeared were edited to change her name to Evelyn, as this was the name of Bill Adama's mother in the ''Battlestar Galactica'' "Hero" documentation. As a result, no character's lips can be seen to speak the name Evelyn in Season 1.0<ref>[http://www.capricatimes.com/the-caprica-times-exclusive-interview-kevin-murphy ''The Caprica Times'' Exclusive Interview: Kevin Murphy]</ref>.

Graf Iblis: /* Pyramid posters */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

A hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of terms such as "day", "month" or "year", there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the ''Caprica'' series and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely took us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this would have taken him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' introduced its own system which is relatively
consistent and widely used on various props.

=== Years ===

Recent years are two-digit numbers, almost always preceded by the letters YR. Several common formats are listed below:

*YR01
*YR 01
*yr01
*01YR

Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42. Years before YR0x are expressed as [[Colonial calendar#Here Be Dragons|YR9x]], while [[Colonial calendar#Unknown episodes|ancient dates]] can be longer than two digits and designated "byr". [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]."

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January
|-

|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || [[Colonial calendar#Unknown episodes|at least 26?]] || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).
[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Guides to artifacts dated at around "400 byr".]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica Museum Of Contemporary Art Poster Set.jpg|x20px]]

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week" ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]
*''The Caprican Comic Pages'' read by [[William "Willie" Adama]] are dated "JUNE 22, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Willies Funny Papers.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx]).
*Sam Adama ("Ross Bailey Framo") was born on Iunius 11, YR92 according to his falsified birth certificate. However, Framo's driver's license appears to give his date of birth as 08-11-? as opposed to 06-11-92YR. The 08 might be a leftover from Joseph's falsified driver's license ([http://caprica.propworx.com Propworx]). [[Image:Caprica Sams Caprican Passport and ID.jpg|x20px]]

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Gemenon Twins]] game are dated "IUNIUS 10, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Pyramid Buccaneers Tickets.jpg|x20px]]

====Unknown episodes====

*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The "FILE DATE" on [[Mar-Beth Willow]]'s GDD file is "12/26/yr42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Mar-Beth GDD Hero File.jpg|x20px]]

====Pyramid posters====

The [http://web.archive.org/web/20101011165818/http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html Profiles in History auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2012-04-30T03:51:37Z

Graf Iblis: /* The Calendar from Caprica */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

A hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of terms such as "day", "month" or "year", there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the ''Caprica'' series and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely took us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this would have taken him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' introduced its own system which is relatively
consistent and widely used on various props.

=== Years ===

Recent years are two-digit numbers, almost always preceded by the letters YR. Several common formats are listed below:

*YR01
*YR 01
*yr01
*01YR

Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42. Years before YR0x are expressed as [[Colonial calendar#Here Be Dragons|YR9x]], while [[Colonial calendar#Unknown episodes|ancient dates]] can be longer than two digits and designated "byr". [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]."

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).
[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Guides to artifacts dated at around "400 byr".]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica Museum Of Contemporary Art Poster Set.jpg|x20px]]

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week" ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]
*''The Caprican Comic Pages'' read by [[William "Willie" Adama]] are dated "JUNE 22, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Willies Funny Papers.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx]).
*Sam Adama ("Ross Bailey Framo") was born on Iunius 11, YR92 according to his falsified birth certificate. However, Framo's driver's license appears to give his date of birth as 08-11-? as opposed to 06-11-92YR. The 08 might be a leftover from Joseph's falsified driver's license ([http://caprica.propworx.com Propworx]). [[Image:Caprica Sams Caprican Passport and ID.jpg|x20px]]

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Gemenon Twins]] game are dated "IUNIUS 10, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Pyramid Buccaneers Tickets.jpg|x20px]]

====Unknown episodes====

*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The "FILE DATE" on [[Mar-Beth Willow]]'s GDD file is "12/26/yr42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Mar-Beth GDD Hero File.jpg|x20px]]

====Pyramid posters====

The [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html Profiles in History auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37
*SEPTEMBER 11, YR37 [[Image:Pyramid_Playoffs_Poster_YR37.jpg|x20px]]

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2012-04-30T03:50:41Z

Graf Iblis: /* Units of Time */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

A hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of terms such as "day", "month" or "year", there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the ''Caprica'' series and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely took us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this would have taken him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

Recent years are two-digit numbers, almost always preceded by the letters YR. Several common formats are listed below:

*YR01
*YR 01
*yr01
*01YR

Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42. Years before YR0x are expressed as [[Colonial calendar#Here Be Dragons|YR9x]], while [[Colonial calendar#Unknown episodes|ancient dates]] can be longer than two digits and designated "byr". [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]."

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).
[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Guides to artifacts dated at around "400 byr".]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica Museum Of Contemporary Art Poster Set.jpg|x20px]]

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week" ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]
*''The Caprican Comic Pages'' read by [[William "Willie" Adama]] are dated "JUNE 22, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Willies Funny Papers.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx]).
*Sam Adama ("Ross Bailey Framo") was born on Iunius 11, YR92 according to his falsified birth certificate. However, Framo's driver's license appears to give his date of birth as 08-11-? as opposed to 06-11-92YR. The 08 might be a leftover from Joseph's falsified driver's license ([http://caprica.propworx.com Propworx]). [[Image:Caprica Sams Caprican Passport and ID.jpg|x20px]]

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Gemenon Twins]] game are dated "IUNIUS 10, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Pyramid Buccaneers Tickets.jpg|x20px]]

====Unknown episodes====

*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The "FILE DATE" on [[Mar-Beth Willow]]'s GDD file is "12/26/yr42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Mar-Beth GDD Hero File.jpg|x20px]]

====Pyramid posters====

The [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html Profiles in History auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2012-04-29T16:44:00Z

Graf Iblis:

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

A hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of terms such as "day", "month" or "year", there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the ''Caprica'' series and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely took us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

Recent years are two-digit numbers, almost always preceded by the letters YR. Several common formats are listed below:

*YR01
*YR 01
*yr01
*01YR

Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42. Years before YR0x are expressed as [[Colonial calendar#Here Be Dragons|YR9x]], while [[Colonial calendar#Unknown episodes|ancient dates]] can be longer than two digits and designated "byr". [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]."

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January
|-
| Februarius || [[The Caprican#Februarius|at least 27]] || February
|-
| Martius || [[The Caprican#Martius|at least 30]] || March
|-
| Aprilis || [[The Caprican#Aprilis|at least 24]] || April
|-
| Maius || [[Colonial calendar#Pyramid posters|at least 27]] || May
|-
| Iunius || [[Colonial calendar#Pyramid posters|at least 27]] || June

|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || [[Colonial calendar#Unknown episodes|at least 26?]] || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).
[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Guides to artifacts dated at around "400 byr".]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica Museum Of Contemporary Art Poster Set.jpg|x20px]]

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week" ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]
*''The Caprican Comic Pages'' read by [[William "Willie" Adama]] are dated "JUNE 22, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Willies Funny Papers.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx]).
*Sam Adama ("Ross Bailey Framo") was born on Iunius 11, YR92 according to his falsified birth certificate. However, Framo's driver's license appears to give his date of birth as 08-11-? as opposed to 06-11-92YR. The 08 might be a leftover from Joseph's falsified driver's license ([http://caprica.propworx.com Propworx]). [[Image:Caprica Sams Caprican Passport and ID.jpg|x20px]]

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Gemenon Twins]] game are dated "IUNIUS 10, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Pyramid Buccaneers Tickets.jpg|x20px]]

====Unknown episodes====

*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The "FILE DATE" on [[Mar-Beth Willow]]'s GDD file is "12/26/yr42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Mar-Beth GDD Hero File.jpg|x20px]]

====Pyramid posters====

The [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html Profiles in History auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-02-19T21:50:44Z

Graf Iblis: /* Years */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

Recent years are two-digit numbers, almost always preceded by the letters YR. Several common formats are listed below:

*YR01
*YR 01
*yr01
*01YR

Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42. Years before YR0x are expressed as [[Colonial calendar#Here Be Dragons|YR9x]], while [[Colonial calendar#Unknown episodes|ancient dates]] can be longer than two digits and designated "byr". [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]."

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January
|-
| Februarius || [[The Caprican#Februarius|at least 27]] || February
|-
| Martius || [[The Caprican#Martius|at least 30]] || March
|-
| Aprilis || [[The Caprican#Aprilis|at least 24]] || April
|-
| Maius || [[Colonial calendar#Pyramid posters|at least 27]] || May
|-
| Iunius || [[Colonial calendar#Pyramid posters|at least 27]] || June
|-
| Quintilis || [[Colonial calendar#Pyramid posters|at least 25]] || July
|-
| Sextilis || [[Colonial calendar#The Imperfections of Memory|at least 14]] || August
|-
| September || [[Colonial calendar#Here Be Dragons|at least 23]] || September
|-
| October || [[The Caprican#October|at least 29]] || October
|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || [[Colonial calendar#Unknown episodes|at least 26?]] || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica Museum Of Contemporary Art Poster Set.jpg|x20px]]

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx]).

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx]).
*Sam Adama ("Ross Bailey Framo") was born on Iunius 11, YR92 according to his falsified birth certificate. However, Framo's driver's license appears to give his date of birth as 08-11-? as opposed to 06-11-92YR. The 08 might be a leftover from Joseph's falsified driver's license ([http://caprica.propworx.com Propworx]). [[Image:Caprica Sams Caprican Passport and ID.jpg|x20px]]

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx]).
*The "FILE DATE" on [[Mar-Beth Willow]]'s GDD file is "12/26/yr42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Mar-Beth GDD Hero File.jpg|x20px]]

====Pyramid posters====

The [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html Profiles in History auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-02-03T22:14:08Z

Graf Iblis:

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is a two-digit number which is usually preceded by the letters YR. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

Recent years [[Colonial calendar#Here Be Dragons|before YR00]] are expressed as YR99 and lower, while [[Colonial calendar#Unknown episodes|ancient dates]] can be greater than 99 and designated "byr". [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January
|-
| Februarius || [[The Caprican#Februarius|at least 27]] || February
|-
| Martius || [[The Caprican#Martius|at least 30]] || March
|-
| Aprilis || [[The Caprican#Aprilis|at least 24]] || April
|-
| Maius || [[Colonial calendar#Pyramid posters|at least 27]] || May
|-
| Iunius || [[Colonial calendar#Pyramid posters|at least 27]] || June
|-
| Quintilis || [[Colonial calendar#Pyramid posters|at least 25]] || July
|-
| Sextilis || [[Colonial calendar#The Imperfections of Memory|at least 14]] || August
|-
| September || [[Colonial calendar#Here Be Dragons|at least 23]] || September
|-
| October || [[The Caprican#October|at least 29]] || October
|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || [[Colonial calendar#Unknown episodes|at least 26?]] || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]], [http://caprica.propworx.com/ Propworx]). [[Image:Caprica Museum Of Contemporary Art Poster Set.jpg|x20px]]

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]
*''The Caprican Comic Pages'' read by [[William "Willie" Adama]] are dated "JUNE 22, YR42" ([http://caprica.propworx.com/ Propworx]). [[Image:Caprica Willies Funny Papers.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx]).
*Sam Adama ("Ross Bailey Framo") was born on Iunius 11, YR92 according to his falsified birth certificate. However, Framo's driver's license appears to give his date of birth as 08-11-? as opposed to 06-11-92YR. The 08 might be a leftover from Joseph's falsified driver's license ([http://caprica.propworx.com Propworx]). [[Image:Caprica Sams Caprican Passport and ID.jpg|x20px]]

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx]).

In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-30T21:18:54Z

Graf Iblis: /* Years */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is a two-digit number which is usually preceded by the letters YR. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

Recent years [[Colonial calendar#Here Be Dragons|before YR00]] are expressed as YR99 and lower, while [[Colonial calendar#Unknown episodes|ancient dates]] can be greater than 99 and designated "byr". [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January
|-
| Februarius || [[The Caprican#Februarius|at least 27]] || February
|-
| Martius || [[The Caprican#Martius|at least 30]] || March
|-
| Aprilis || [[The Caprican#Aprilis|at least 24]] || April
|-
| Maius || [[Colonial calendar#Pyramid posters|at least 27]] || May
|-
| Iunius || [[Colonial calendar#Pyramid posters|at least 27]] || June
|-
| Quintilis || [[Colonial calendar#Pyramid posters|at least 25]] || July
|-
| Sextilis || [[Colonial calendar#The Imperfections of Memory|at least 14]] || August
|-
| September || [[Colonial calendar#Here Be Dragons|at least 23]] || September
|-
| October || [[The Caprican#October|at least 29]] || October
|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || [[Colonial calendar#Unknown episodes|at least 26?]] || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Museum Of Contemporary Art Poster Set.jpg|x20px]]

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]
*''The Caprican Comic Pages'' read by [[William "Willie" Adama]] are dated "JUNE 22, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Willies Funny Papers.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).
*Sam Adama ("Ross Bailey Framo") was born on Iunius 11, YR92 according to his falsified birth certificate. However, Framo's driver's license appears to give his date of birth as 08-11-? as opposed to 06-11-92YR. The 08 might be a leftover from Joseph's falsified driver's license ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica Sams Caprican Passport and ID.jpg|x20px]]

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Gemenon Twins]] game are dated "IUNIUS 10, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Pyramid Buccaneers Tickets.jpg|x20px]]

====Unknown episodes====

[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Guides to artifacts dated at around "400 byr".]]
*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx auction]).
*The "FILE DATE" on [[Mar-Beth Willow]]'s GDD file is "12/26/yr42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Mar-Beth GDD Hero File.jpg|x20px]]

====Pyramid posters====

The [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html Profiles in History auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-30T21:17:57Z

Graf Iblis: /* Years */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is a two-digit number which is usually preceded by the letters YR. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

Recent years [[Colonial calendar#Here Be Dragons|before YR00]] are expressed as YR99 and lower, while [[Colonial calendar#unknown episodes|ancient dates]] can be greater than 99 and designated "byr". [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January
|-
| Februarius || [[The Caprican#Februarius|at least 27]] || February
|-
| Martius || [[The Caprican#Martius|at least 30]] || March
|-
| Aprilis || [[The Caprican#Aprilis|at least 24]] || April
|-
| Maius || [[Colonial calendar#Pyramid posters|at least 27]] || May
|-
| Iunius || [[Colonial calendar#Pyramid posters|at least 27]] || June
|-

|-
| September || [[Colonial calendar#Here Be Dragons|at least 23]] || September
|-
| October || [[The Caprican#October|at least 29]] || October
|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || [[Colonial calendar#Unknown episodes|at least 26?]] || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Museum Of Contemporary Art Poster Set.jpg|x20px]]

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]
*''The Caprican Comic Pages'' read by [[William "Willie" Adama]] are dated "JUNE 22, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Willies Funny Papers.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).
*Sam Adama ("Ross Bailey Framo") was born on Iunius 11, YR92 according to his falsified birth certificate. However, Framo's driver's license appears to give his date of birth as 08-11-? as opposed to 06-11-92YR. The 08 might be a leftover from Joseph's falsified driver's license ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica Sams Caprican Passport and ID.jpg|x20px]]

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Gemenon Twins]] game are dated "IUNIUS 10, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Pyramid Buccaneers Tickets.jpg|x20px]]

====Unknown episodes====

[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Guides to artifacts dated at around "400 byr".]]
*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx auction]).
*The "FILE DATE" on [[Mar-Beth Willow]]'s GDD file is "12/26/yr42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Mar-Beth GDD Hero File.jpg|x20px]]

====Pyramid posters====

The [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html Profiles in History auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-30T21:00:46Z

Graf Iblis: /* Apotheosis */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is a two-digit number which is usually preceded by the letters YR. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

Recent years [[Colonial calendar#Here Be Dragons|before YR00]] are expressed as YR99 and lower. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January
|-
| Februarius || [[The Caprican#Februarius|at least 27]] || February
|-
| Martius || [[The Caprican#Martius|at least 30]] || March
|-
| Aprilis || [[The Caprican#Aprilis|at least 24]] || April
|-
| Maius || [[Colonial calendar#Pyramid posters|at least 27]] || May

|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || [[Colonial calendar#Unknown episodes|at least 26?]] || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Museum Of Contemporary Art Poster Set.jpg|x20px]]

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]
*''The Caprican Comic Pages'' read by [[William "Willie" Adama]] are dated "JUNE 22, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Willies Funny Papers.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).
*Sam Adama ("Ross Bailey Framo") was born on Iunius 11, YR92 according to his falsified birth certificate. However, Framo's driver's license appears to give his date of birth as 08-11-? as opposed to 06-11-92YR. The 08 might be a leftover from Joseph's falsified driver's license ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica Sams Caprican Passport and ID.jpg|x20px]]

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Gemenon Twins]] game are dated "IUNIUS 10, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Pyramid Buccaneers Tickets.jpg|x20px]]

====Unknown episodes====

[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Guides to artifacts dated at around "400 byr".]]
*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx auction]).
*The "FILE DATE" on [[Mar-Beth Willow]]'s GDD file is "12/26/yr42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Mar-Beth GDD Hero File.jpg|x20px]]

====Pyramid posters====

The [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html Profiles in History auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Graf Iblis: /* The Calendar from Caprica */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is a two-digit number which is usually preceded by the letters YR. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

Recent years [[Colonial calendar#Here Be Dragons|before YR00]] are expressed as YR99 and lower. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January
|-
| Februarius || [[The Caprican#Februarius|at least 27]] || February
|-
| Martius || [[The Caprican#Martius|at least 30]] || March
|-
| Aprilis || [[The Caprican#Aprilis|at least 24]] || April
|-
| Maius || [[Colonial calendar#Pyramid posters|at least 27]] || May

|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || [[Colonial calendar#Unknown episodes|at least 26?]] || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Museum Of Contemporary Art Poster Set.jpg|x20px]]

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]
*''The Caprican Comic Pages'' read by [[William "Willie" Adama]] are dated "JUNE 22, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Willies Funny Papers.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).
*Sam Adama ("Ross Bailey Framo") was born on Iunius 11, YR92 according to his falsified birth certificate. However, Framo's driver's license appears to give his date of birth as 08-11-? as opposed to 06-11-92YR. The 08 might be a leftover from Joseph's falsified driver's license ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica Sams Caprican Passport and ID.jpg|x20px]]

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Guides to artifacts dated at around "400 byr".]]
*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx auction]).
*The "FILE DATE" on [[Mar-Beth Willow]]'s GDD file is "12/26/yr42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Mar-Beth GDD Hero File.jpg|x20px]]

====Pyramid posters====

The [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html Profiles in History auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37
*SEPTEMBER 11, YR37 [[Image:Pyramid_Playoffs_Poster_YR37.jpg|x20px]]

*Iunius 12, YR37 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR37.jpg|x20px]]

*MARTIUS 19, YR39
*MARTIUS 27, YR39
*MAIUS 22, YR39
*MAIUS 27, YR39
*IUNIUS 5, YR39
*IUNIUS 27, YR39 [[Image:Pyramid_Playoffs_Poster_YR39.jpg|x20px]]

*Quintilis 25, YR39 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR39.jpg|x20px]]

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-30T20:48:40Z

Graf Iblis: /* Pyramid posters */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is a two-digit number which is usually preceded by the letters YR. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

Recent years [[Colonial calendar#Here Be Dragons|before YR00]] are expressed as YR99 and lower. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January
|-
| Februarius || [[The Caprican#Februarius|at least 27]] || February
|-
| Martius || [[The Caprican#Martius|at least 30]] || March
|-
| Aprilis || [[The Caprican#Aprilis|at least 24]] || April
|-

|-
| October || [[The Caprican#October|at least 29]] || October
|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || unknown || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Museum Of Contemporary Art Poster Set.jpg|x20px]]

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]
*''The Caprican Comic Pages'' read by [[William "Willie" Adama]] are dated "JUNE 22, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Willies Funny Papers.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).
*Sam Adama ("Ross Bailey Framo") was born on Iunius 11, YR92 according to his falsified birth certificate. However, Framo's driver's license appears to give his date of birth as 08-11-? as opposed to 06-11-92YR. The 08 might be a leftover from Joseph's falsified driver's license ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica Sams Caprican Passport and ID.jpg|x20px]]

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Guides to artifacts dated at around "400 byr".]]
*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx auction]).
*The "FILE DATE" on [[Mar-Beth Willow]]'s GDD file is "12/26/yr42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Mar-Beth GDD Hero File.jpg|x20px]]

====Pyramid posters====

The [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html Profiles in History auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-30T20:45:24Z

Graf Iblis: /* Unknown episodes */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is a two-digit number which is usually preceded by the letters YR. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

Recent years [[Colonial calendar#Here Be Dragons|before YR00]] are expressed as YR99 and lower. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January

|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || unknown || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Museum Of Contemporary Art Poster Set.jpg|x20px]]

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]
*''The Caprican Comic Pages'' read by [[William "Willie" Adama]] are dated "JUNE 22, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Willies Funny Papers.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).
*Sam Adama ("Ross Bailey Framo") was born on Iunius 11, YR92 according to his falsified birth certificate. However, Framo's driver's license appears to give his date of birth as 08-11-? as opposed to 06-11-92YR. The 08 might be a leftover from Joseph's falsified driver's license ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica Sams Caprican Passport and ID.jpg|x20px]]

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Guides to artifacts dated at around "400 byr".]]
*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx auction]).
*The "FILE DATE" on [[Mar-Beth Willow]]'s GDD file is "12/26/yr42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Mar-Beth GDD Hero File.jpg|x20px]]

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-30T20:32:54Z

Graf Iblis: /* False Labor */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is a two-digit number which is usually preceded by the letters YR. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

Recent years [[Colonial calendar#Here Be Dragons|before YR00]] are expressed as YR99 and lower. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Museum Of Contemporary Art Poster Set.jpg|x20px]]

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]
*''The Caprican Comic Pages'' read by [[William "Willie" Adama]] are dated "JUNE 22, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Willies Funny Papers.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).
*Sam Adama ("Ross Bailey Framo") was born on Iunius 11, YR92 according to his falsified birth certificate. However, Framo's driver's license appears to give his date of birth as 08-11-? as opposed to 06-11-92YR. The 08 might be a leftover from Joseph's falsified driver's license ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica Sams Caprican Passport and ID.jpg|x20px]]

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Guides to artifacts dated at around "400 byr".]]
*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx auction]).

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37
*SEPTEMBER 11, YR37

*Iunius 12, YR37 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR37.jpg|x20px]]

*MARTIUS 19, YR39
*MARTIUS 27, YR39
*MAIUS 22, YR39
*MAIUS 27, YR39
*IUNIUS 5, YR39
*IUNIUS 27, YR39

*Quintilis 25, YR39 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR39.jpg|x20px]]

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-30T20:18:56Z

Graf Iblis: /* Evidence from the series */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is a two-digit number which is usually preceded by the letters YR. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

Recent years [[Colonial calendar#Here Be Dragons|before YR00]] are expressed as YR99 and lower. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"

|-
| December? || unknown || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica Museum Of Contemporary Art Poster Set.jpg|x20px]]

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).
*Sam Adama ("Ross Bailey Framo") was born on Iunius 11, YR92 according to his falsified birth certificate. However, Framo's driver's license appears to give his date of birth as 08-11-? as opposed to 06-11-92YR. The 08 might be a leftover from Joseph's falsified driver's license ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica Sams Caprican Passport and ID.jpg|x20px]]

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Guides to artifacts dated at around "400 byr".]]
*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx auction]).

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-30T20:09:37Z

Graf Iblis: /* Here Be Dragons */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is a two-digit number which is usually preceded by the letters YR. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

Recent years [[Colonial calendar#Here Be Dragons|before YR00]] are expressed as YR99 and lower. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January
|-
| Februarius || [[The Caprican#Februarius|at least 27]] || February
|-
| Martius || [[The Caprican#Martius|at least 30]] || March
|-
| Aprilis || [[The Caprican#Aprilis|at least 24]] || April
|-
| Maius || [[Colonial calendar#Pyramid posters|at least 27]] || May
|-
| Iunius || [[Colonial calendar#Pyramid posters|at least 27]] || June
|-
| Quintilis || [[Colonial calendar#Pyramid posters|at least 25]] || July
|-
| Sextilis || [[Colonial calendar#The Imperfections of Memory|at least 14]] || August
|-
| September || [[Colonial calendar#Here Be Dragons|at least 23]] || September
|-
| October || [[The Caprican#October|at least 29]] || October
|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || unknown || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:

*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).
*Sam Adama ("Ross Bailey Framo") was born on Iunius 11, YR92 according to his falsified birth certificate. However, Framo's driver's license appears to give his date of birth as 08-11-? as opposed to 06-11-92YR. The 08 might be a leftover from Joseph's falsified driver's license ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica Sams Caprican Passport and ID.jpg|x20px]]

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Guides to artifacts dated at around "400 byr".]]
*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx auction]).

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

The Caprican

2011-01-29T12:41:24Z

Graf Iblis: /* Features as of last update */

[[Image:The Caprican logo.jpg|thumb|"And since things move at the speed of light in our city by the sea, blink and you'll miss something. That's where ''The Caprican'' comes in."]]
'''''The Caprican''''' was a daily periodical in existence by [[Colonial calendar#The Calendar from Caprica|YR42]], 58 years before the [[Fall of the Twelve Colonies]]. It ran news, entertainment, cultural, financial, and sports articles, as well as editorial columns and a section entitled "Playing the Field" (a reference to [[Pyramid (RDM)|Pyramid]]), where readers could write in to the paper for advice on love, dating, and marriage.

News articles are color-coded with black headings, Sports with orange, Opinion with purple, Lifestyle with green, Entertainment with red, and Politics with blue.

== Syfy Blog ==

''The Caprican'' is available as an online companion to the events of [[Caprica (series)|''Caprica'']], releasing stories that pertain to the plot both before and after episodes air, as well as giving background on culture seen in the series. It is available for viewing on the web as well as an App for Apple iPhone and iPod Touch. The blog appeared shortly before the series went on the air and the initial publishing run continued as late as a month after Season 1.0. The hiatus that followed ended just before Season 1.5 began, but the pause had been explained in-universe on July 27:

:... the truth is that certain interests in the higher echelons of [[Caprica City]] society took some issue with a few of the things we'd published in the past few months. We won't go into the gory details, but we were unfortunately forced to cease and desist while the guys with the briefcases sorted things out ... We've received word that the red tape is beginning to clear, and so we'll be returning to action in the very near future ...

No articles have been published since the series was cancelled. The article titles, fictional dates and real-world dates of publication in 2010 are listed below. The fictional dates were calculated apparently by adding a variable number of days to the dates of publication. For example, the articles published between March 2 and April 30 use dates of YR42 which are three days later than the corresponding publication dates, so March 2 became Martius 5 and April 30 became Maius 3.

The Caprican

2011-01-29T12:36:06Z

Graf Iblis: /* Syfy Blog */

[[Image:The Caprican logo.jpg|thumb|"And since things move at the speed of light in our city by the sea, blink and you'll miss something. That's where ''The Caprican'' comes in."]]
'''''The Caprican''''' was a daily periodical in existence by [[Colonial calendar#The Calendar from Caprica|YR42]], 58 years before the [[Fall of the Twelve Colonies]]. It ran news, entertainment, cultural, financial, and sports articles, as well as editorial columns and a section entitled "Playing the Field" (a reference to [[Pyramid (RDM)|Pyramid]]), where readers could write in to the paper for advice on love, dating, and marriage.

News articles are color-coded with black headings, Sports with orange, Opinion with purple, Lifestyle with green, Entertainment with red, and Politics with blue.

== Syfy Blog ==

''The Caprican'' is available as an online companion to the events of [[Caprica (series)|''Caprica'']], releasing stories that pertain to the plot both before and after episodes air, as well as giving background on culture seen in the series. It is available for viewing on the web as well as an App for Apple iPhone and iPod Touch. The blog appeared shortly before the series went on the air and the initial publishing run continued as late as a month after Season 1.0. The hiatus that followed ended just before Season 1.5 began, but the pause had been explained in-universe on July 27:

:... the truth is that certain interests in the higher echelons of [[Caprica City]] society took some issue with a few of the things we'd published in the past few months. We won't go into the gory details, but we were unfortunately forced to cease and desist while the guys with the briefcases sorted things out ... We've received word that the red tape is beginning to clear, and so we'll be returning to action in the very near future ...

No articles have been published since the series was cancelled. The article titles, fictional dates and real-world dates of publication in 2010 are listed below. The fictional dates were calculated apparently by adding a variable number of days to the dates of publication. For example, the articles published between March 2 and April 30 use dates of YR42 which are three days later than the corresponding publication dates, so March 2 became Martius 5 and April 30 became Maius 3.

Colonial calendar

2011-01-28T20:34:59Z

Graf Iblis: /* Gravedancing */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is a two-digit number which is usually preceded by the letters YR. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01

Recent years [[Colonial calendar#Here Be Dragons|before YR00]] are expressed as YR99 and lower. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]
*Sandhano Schultz's badge from the same talk show is marked "EXP.09 YR 45" ([http://caprica.propworx.com Propworx auction]). [[Image:Caprica_Sandhano_Schultz_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Guides to artifacts dated at around "400 byr".]]
*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx auction]).

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37
*SEPTEMBER 11, YR37

*Iunius 12, YR37 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR37.jpg|x20px]]

*MARTIUS 19, YR39

*MAIUS 22, YR39
*MAIUS 27, YR39
*IUNIUS 5, YR39
*IUNIUS 27, YR39

*Quintilis 25, YR39 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR39.jpg|x20px]]

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-24T22:20:10Z

Graf Iblis: /* Unknown episodes */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is a two-digit number which is usually preceded by the letters YR. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

Recent years [[Colonial calendar#Here Be Dragons|before YR00]] are expressed as YR99 and lower. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January

|-
| October || [[The Caprican#October|at least 29]] || October
|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || unknown || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Guides to artifacts dated at around "400 byr".]]
*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx auction]).

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37
*SEPTEMBER 11, YR37

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-24T22:12:39Z

Graf Iblis: /* Unknown episodes */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is a two-digit number which is usually preceded by the letters YR. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

Recent years [[Colonial calendar#Here Be Dragons|before YR00]] are expressed as YR99 and lower. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January
|-
| Februarius || [[The Caprican#Februarius|at least 27]] || February
|-
| Martius || [[The Caprican#Martius|at least 30]] || March
|-
| Aprilis || [[The Caprican#Aprilis|at least 24]] || April
|-
| Maius || [[Colonial calendar#Pyramid posters|at least 27]] || May
|-
| Iunius || [[Colonial calendar#Pyramid posters|at least 27]] || June
|-
| Quintilis || [[Colonial calendar#Pyramid posters|at least 25]] || July
|-
| Sextilis || [[Colonial calendar#The Imperfections of Memory|at least 14]] || August
|-
| September || [[Colonial calendar#Here Be Dragons|at least 23]] || September
|-
| October || [[The Caprican#October|at least 29]] || October
|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || unknown || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Artifacts dated at around "400 byr".]]
*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol ([http://caprica.propworx.com/ Propworx auction]).

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-24T22:08:05Z

Graf Iblis: /* Unknown episodes */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is a two-digit number which is usually preceded by the letters YR. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

Recent years [[Colonial calendar#Here Be Dragons|before YR00]] are expressed as YR99 and lower. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January
|-
| Februarius || [[The Caprican#Februarius|at least 27]] || February
|-
| Martius || [[The Caprican#Martius|at least 30]] || March
|-
| Aprilis || [[The Caprican#Aprilis|at least 24]] || April
|-
| Maius || [[Colonial calendar#Pyramid posters|at least 27]] || May
|-
| Iunius || [[Colonial calendar#Pyramid posters|at least 27]] || June
|-
| Quintilis || [[Colonial calendar#Pyramid posters|at least 25]] || July
|-
| Sextilis || [[Colonial calendar#The Imperfections of Memory|at least 14]] || August
|-
| September || [[Colonial calendar#Here Be Dragons|at least 23]] || September
|-
| October || [[The Caprican#October|at least 29]] || October
|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || unknown || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

[[Image:Caprica_Caprican_Museum_Pamphlets.jpg|thumb|Artifacts dated at around "400 byr".]]
*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]
*The ''Art Treasures of Kobol'' pamphlet by the Caprican Art Museum dates three artifacts at "Circa 400 byr". The "yr" and the exhibit run from "IUNIUS 15 THROUGH QUINTILIS 25" suggest that the year was intended to fit within the established calendar. If SergeGraystone's data is correct, the simplest explanation would be 400 years before the current era, which began 1,942 years ago with the exodus from Kobol.

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37
*SEPTEMBER 11, YR37

*Iunius 12, YR37 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR37.jpg|x20px]]

*MARTIUS 19, YR39
*MARTIUS 27, YR39
*MAIUS 22, YR39
*MAIUS 27, YR39
*IUNIUS 5, YR39
*IUNIUS 27, YR39

*Quintilis 25, YR39 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR39.jpg|x20px]]

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

'''Tomas Vergis''' is a [[Tauron (RDM)|Tauron]] computer scientist and competitor of [[Daniel Graystone]]. Like Daniel, he leads his own computer and robotics corporation, the [[Vergis Corporation]].

After [[Zoe Graystone|his daughter's]] death in a suicide bombing, Daniel, with the help of Tauron attorney [[Joseph Adama]], steal Vergis's technology, a [[meta-cognitive processor]] (MCP) in order to revive their daughters in robotic bodies, thus creating the first [[Cylons (RDM)|Cylons]]. Vergis does not take legal action against Daniel or his company, although rumors and suspicions about the theft circulate within the [[Caprica (RDM)|Caprican]] Ministry of Defense ([[CAP]]: ''[[Caprica pilot]]'').

Approximately a month and a half after the bombing, Vergis arrives on Caprica and personally confronts Daniel about the theft, informing him that two of his employees--close relatives and friends on Tauron--were murdered in the process. Soon afterward, he offers to buy the [[Caprica Buccaneers]] [[Pyramid (RDM)|pyramid]] team from Daniel, reminding him that his company is short on cash and that an infusion of liquidity from the team's sale would give them time to resolve problems with [[U-87]] development. The offer to buy the C-Bucs, however, is revealed to be the first step in a personal vendetta against Graystone for the theft and murders, to strip him of the things he loves and ultimately "tear up your dream."

During this trip, Vergis makes time for a public relations campaign, appearing as a guest on ''[[Backtalk with Baxter Sarno]]'' and surprising the audience with news that he will permanently relocate to Caprica and apply for Caprican citizenship ([[CAP]]: "[[Know Thy Enemy]]").

Some time later, Vergis visits [[Amanda Graystone]], and tells her about the crimes and her husband's involvement in them ([[CAP]]: "[[Ghosts in the Machine]]"). After initially denying it, the information [[End of Line|horrifies her and threatens both her marriage and her emotional stability]].

Recognizing that the U-87 relies upon stolen technology and that Graystone Industries will be unable to meet its deadline for delivery of one hundred thousand copies of the robot, Colonel [[Sasha Patel]] formally offers Vergis the contract for U-87 production, paving the way for him to become the corporation's CEO ([[CAP]]: "[[End of Line]]"). As the new public face of Graystone Industries, Vergis proudly boasts the now-successful mass production of U-87s. Behind the scenes, he continues to strip away Daniel's influence over the corporation by, among other things, ordering the destruction of the ruined prototype U-87 ([[CAP]]: "[[Unvanquished]]"). Vergis' successes are not enough to preserve his position as CEO. A blackmail campaign orchestrated by Daniel and the [[Ha'la'tha]] convinces the board of directors to vote unanimously against him in favor of Daniel ([[CAP]]: "[[Things We Lock Away]]").

Vergis quickly recognizes the hand of the Ha'la'tha in his overthrow, and knows that the crime syndicate will eventually kill him. He visits Daniel and asks for his help in ending his life at a time and manner of his own choosing. For a moment, Vergis seems to agree to Daniel's proposal of an alliance in resisting the Ha'la'tha, but when Daniel relaxes and steps closer to him, Vergis takes advantage of the moment, forces Daniel's hand onto the grip of a knife, and pushes the blade into his own chest ([[CAP]]: "[[Things We Lock Away]]"). It is unknown if the public is aware of his death.

==Notes==
*Although reported in various sites that Vergis would be played by [[Roger R. Cross]], he is absent in both the finished pilot and the accompanying deleted scenes. ''Spoiler TV'' published a casting call for Vergis indicating that the character was to be introduced in the episode "[[Know Thy Enemy]]", which later proved accurate.<ref>{{cite_web|url=http://www.spoilertv.com/2009/07/exclusive-caprica-episode-106-know-thy.html|title=Exclusive - Caprica - Episode 1.06 - Know Thy Enemy - Casting Call |date=July 28, 2009|accessdate=December 19, 2009|last=|first=|format=|language=English}}</ref> However, the casting of Roger Cross seem to have been legitimate as can be viewed on [http://www.rogercross.net/projects.htm Cross's official (albeit outdated) site]. There was even a still from the pilot featuring Vergis as portrayed by Cross displayed at Syfy's official ''Caprica'' gallery, but has since been removed.<ref>{{cite_web|url=http://community.livejournal.com/battlestar_blog/1890930.html|title=battlestar_blog: First picture of Luciana in Caprica|date=December 4, 2009|accessdate=December 19, 2009|last=|first=|format=|language=English}}</ref> <ref>{{cite_web|url=http://www.syfy.com/caprica/photos.php?sub=amanda_graystone|title=Amanda Graystone Photos |date=|accessdate=December 19, 2009|last=|first=|format=|language=English}}</ref>

Colonial calendar

2011-01-16T20:10:02Z

Graf Iblis: /* Years */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is a two-digit number which is usually preceded by the letters YR. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

Recent years [[Colonial calendar#Here Be Dragons|before YR00]] are expressed as YR99 and lower. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 stated] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January
|-
| Februarius || [[The Caprican#Februarius|at least 27]] || February
|-
| Martius || [[The Caprican#Martius|at least 30]] || March
|-
| Aprilis || [[The Caprican#Aprilis|at least 24]] || April
|-
| Maius || [[Colonial calendar#Pyramid posters|at least 27]] || May
|-
| Iunius || [[Colonial calendar#Pyramid posters|at least 27]] || June
|-
| Quintilis || [[Colonial calendar#Pyramid posters|at least 25]] || July
|-
| Sextilis || [[Colonial calendar#The Imperfections of Memory|at least 14]] || August
|-
| September || [[Colonial calendar#Here Be Dragons|at least 23]] || September
|-
| October || [[The Caprican#October|at least 29]] || October
|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || unknown || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37
*SEPTEMBER 11, YR37

*Iunius 12, YR37 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR37.jpg|x20px]]

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-16T19:47:19Z

Graf Iblis: /* Date format */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is usually composed of the letters YR and a two-digit number. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

YR99 and lower [[Colonial calendar#Here Be Dragons|precede]] YR00. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 added] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January
|-
| Februarius || [[The Caprican#Februarius|at least 27]] || February
|-
| Martius || [[The Caprican#Martius|at least 30]] || March
|-
| Aprilis || [[The Caprican#Aprilis|at least 24]] || April
|-
| Maius || [[Colonial calendar#Pyramid posters|at least 27]] || May

|-
| October || [[The Caprican#October|at least 29]] || October
|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || unknown || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. Some examples, in no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-16T19:40:17Z

Graf Iblis: /* Months */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is usually composed of the letters YR and a two-digit number. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

YR99 and lower [[Colonial calendar#Here Be Dragons|precede]] YR00. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 added] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! ''CAPRICA'' MONTH !! DAYS PER MONTH !! GREGORIAN MONTH
|-
| Ianuarius || [[The Caprican#Ianuarius|at least 23]] || January
|-
| Februarius || [[The Caprican#Februarius|at least 27]] || February
|-
| Martius || [[The Caprican#Martius|at least 30]] || March
|-
| Aprilis || [[The Caprican#Aprilis|at least 24]] || April
|-
| Maius || [[Colonial calendar#Pyramid posters|at least 27]] || May
|-
| Iunius || [[Colonial calendar#Pyramid posters|at least 27]] || June
|-
| Quintilis || [[Colonial calendar#Pyramid posters|at least 25]] || July
|-
| Sextilis || [[Colonial calendar#The Imperfections of Memory|at least 14]] || August
|-
| September || [[Colonial calendar#Here Be Dragons|at least 23]] || September
|-
| October || [[The Caprican#October|at least 29]] || October
|-
| November || [[The Caprican#November|at least 16]] || November
|-
| December? || unknown || December
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but there appear to be variations as well: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. In no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37
*SEPTEMBER 11, YR37

*Iunius 12, YR37 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR37.jpg|x20px]]

*MARTIUS 19, YR39
*MARTIUS 27, YR39
*MAIUS 22, YR39
*MAIUS 27, YR39
*IUNIUS 5, YR39
*IUNIUS 27, YR39

*Quintilis 25, YR39 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR39.jpg|x20px]]

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-15T17:38:23Z

Graf Iblis: /* Different Timekeeping Methods */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is usually composed of the letters YR and a two-digit number. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

YR99 and lower [[Colonial calendar#Here Be Dragons|precede]] YR00. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 added] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! GREGORIAN MONTH !! ''CAPRICA'' MONTH !! DAYS PER MONTH ON ''CAPRICA''
|-
| January || Ianuarius || [[The Caprican#Ianuarius|at least 23]]

|-
| March || Martius || [[The Caprican#Martius|at least 30]]

|-
| October || October || [[The Caprican#October|at least 29]]
|-
| November || November || [[The Caprican#November|at least 16]]
|-
| December || December? || unknown
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but we have also seen what appear to be alternate names: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. In no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37
*SEPTEMBER 11, YR37

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Other Calendars ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-15T17:36:43Z

Graf Iblis: /* Analysis of William Adama's Dossier */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is usually composed of the letters YR and a two-digit number. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

YR99 and lower [[Colonial calendar#Here Be Dragons|precede]] YR00. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 added] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but we have also seen what appear to be alternate names: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. In no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37
*SEPTEMBER 11, YR37

*Iunius 12, YR37 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR37.jpg|x20px]]

*MARTIUS 19, YR39
*MARTIUS 27, YR39
*MAIUS 22, YR39
*MAIUS 27, YR39
*IUNIUS 5, YR39
*IUNIUS 27, YR39

*Quintilis 25, YR39 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR39.jpg|x20px]]

==Analysis of William Adama's Dossier==
[[Image:Dossier.png|thumb|Adama's dossier.]]
In "[[Hero]]", [[William Adama]]'s dossier can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Different Timekeeping Methods ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Timeline (RDM)

2011-01-15T17:05:30Z

Graf Iblis: /* Recent Colonial History */

{{timeline series}}

This article plots the events which were shown or mentioned in the history of [[The Twelve Colonies (RDM)|the Twelve Colonies]] from the [[Re-imagined Series]] and [[Caprica (series)|Caprica]].

By convention, all dates are relative to the [[Fall of the Twelve Colonies]]. Events before the Fall are marked as "BCH", or "Before Cylon holocaust". Given the few and somewhat contradictory dates about the Colonials' ancient history and the exodus from Kobol, that part of the timeline is speculative.

The Cylon holocaust occurs more than 150,000 years ago.

==Ancient History==
:''See also: [[History of the Twelve Colonies]], [[Sacred_Scrolls#Analysis|Sacred Scrolls]]''
*'''Unspecified time period:''' Humans on the planet [[Kobol (RDM)|Kobol]] organize themselves into twelve tribes ([[Miniseries]]). According to [[Sacred Scrolls|at least one scripture]], they "live in utopia with the gods." The humans become sufficiently advanced to establish viable space travel and artificial, robotic life. Artificial life-forms, machine similar in nature to the later day Cylons, are created by the humans. A war against the machines occurs. At one point the machines evolve and take humanoid form, either before, during or after the war. This group of humanoid Cylons are later referred to in the Sacred Scrolls as the "[[Thirteenth Tribe (RDM)|Thirteenth Tribe]]," although said text does not specify that they were a tribe of Cylons ([[Sometimes a Great Notion]]).
*'''Over 17,000 years BCH:''' A supernova creates the [[Ionian nebula]].
*'''ca. 4,000 years BCH:''' The Thirteenth Tribe reportedly leaves Kobol and builds the [[The Temple of Five|Temple of Hopes]] on [[Algae planet|another planet]] <ref name="kobol">Tyrol says that "Our initial radiocarbon dating suggests that the temple's at least 4,000 years old, which lines up with the exodus of the Thirteenth Tribe." ([[The Eye of Jupiter]]). This is the oldest date noted in the series's timeline, but also conflicts with the prior date of Pythia and her works as described by [[Elosha]] in "[[Kobol's Last Gleaming, Part I]]", where she states that the exodus of '''all 13 tribes''' occurred approximately 2,000 years ago.</ref> This contradicts [[Ellen Tigh]]'s statement that the temple was built 3,000 years ago ([[No Exit]]). They pray for guidance and are shown the way to [[Earth (RDM)|Earth]], the planet they colonize.
*'''ca. 3,600 years BCH:''' [[Pythia]] records [[Sacred Scrolls#The Book of Pythia|her prophecies.]] Aside from reports of the landing on Earth and drawings of [[Temple of Aurora|temple]]s there, this book describes "the exile and rebirth of the human race" and a "dying leader" not making it to a "promised land," though how long before her writings that such events took place is not revealed.
*'''ca. 3,000 years BCH:''' A [[Lion's Head beacon|beacon]] is left at the [[Lion's Head Nebula]], later marking the way to Earth. At some undated point, someone travels from [[Earth (RDM)|Earth]] to Kobol, passing on information about Earth, including a map of its night sky <ref>Adama says that "According to Cottle, the [[Lymphocytic encephalitis|virus]] was an exact match to one reported over 3000 years ago, right around the time that the 13th colony left Kobol" ([[A Measure of Salvation]]). This contradicts the two other dates of 2,000 and 4,000 years. While the dating is uncertain, it is the only clue to the beacon's age. That someone traveled back to Kobol is speculation, but an explanation for how Earth's sky could be displayed there. If true, it is still unknown on which of these two voyages the beacon was left behind.</ref>
*'''ca. 3,000 years to 2,000 years BCH:''' The humanoid Cylons of the Thirteenth Tribe prosper and begin to reproduce sexually. The technology of "[[Resurrection (RDM)|organic memory transfer]]," or downloading, is abandoned.
**The Thirteenth Tribe produce their own mechanical Centurions to act as laborers for their civilization.
*'''ca. 2,000 years BCH:''' (''The order of events on Kobol and Earth is uncertain.'')
**[[Samuel Anders]], [[Tory Foster]], [[Ellen Tigh]], [[Saul Tigh]], and [[Galen Tyrol]], later collectively known as the "Final Five," are born on Earth.
**The Final Five work together in a research lab attempting to re-develop downloading technology. The effort is spearheaded by Galen Tyrol and Ellen Tigh.
**All five Cylons receive visions of beings nobody else can see warning them of an impending rebellion by Earth's Centurion population. The Final Five prepare a resurrection ship and leave it in orbit.
**The remaining Twelve Tribes leave Kobol and settle the [[Twelve Colonies (RDM)|Twelve Colonies]]<ref name="kobol"/>.
**Lord of Kobol "Athena" kills herself in despair over this. A [[Tomb of Athena|tomb]] is built for her containing a 3-D projection showing Earth and its Zodiac. The projection is activated by the Arrow of Apollo, which travels with the twelve tribes.
**The Centurion uprising occurs and the Thirteenth Tribe exterminates itself in a nuclear holocaust. Earth is left a nuclear wasteland. The Final Five die in the attack, and are resurrected on board their orbiting ship.
**The Final Five begin a journey back to Kobol to find the other twelve tribes and inform them of Earth's fate. They are aware of the cyclical nature of history and believe that the twelve tribes will create Cylons again. They want to warn them to treat them right. However, their ship is not equipped with a conventional FTL drive and journeys at relativistic sublight speeds.
*'''2,000 years to 52 years BCH:''' The Twelve Colonies grow and prosper. Each colony acts as a sovereign nation, complete with inter-colonial wars.
**The Final Five stop at the Temple of Hopes as they retrace their tribe's path.
**The Final Five arrive at Kobol, finding the planet abandoned. They continue on in pursuit of the twelve tribes, heading toward the colonies.

==Recent Colonial History==

''The most recent history could also be dated using the [[Colonial calendar#The Calendar from Caprica|calendar from ''Caprica'']], but the method wasn't used in the re-imagined series and remained in the background even on the new show. Furthermore, we don't know whether the calendar is specific to the planet Caprica or common to the twelve worlds.

*'''At least 200 years BCH:''' Humans develop an immunity to the virus causing [[Lymphocytic encephalitis]] ([[A Measure of Salvation]]). <ref>Doctor Cottle notes the time as "a couple hundred years ago", which is an indeterminate amount of time, but likely less than four or five hundred years.</ref>
*'''ca. 93 BCH:''' [[Tauron Civil War]] causes emigration of [[Joseph Adama|Joseph]] and [[Sam Adama]] to [[Caprica (RDM)|Caprica]] to live in an orphanage. Joseph later becomes a lawyer thanks to the education funded by the [[Ha'la'tha]] crime syndicate; Sam becomes an assassin for Ha'la'tha ([[Caprica pilot]]).
*'''69 years BCH:'''
**[[Saul Tigh]] supposedly born (defined by deleted scene in "[[Valley of Darkness]]" concerning the ''[[Brenik]]''). This is actually a fabrication by [[John Cavil]].
*'''58—52 years BCH:''' With the use of a meta-cognitive processor stolen from Tauron rival [[Tomas Vergis]], the Caprican tech CEO [[Daniel Graystone]] creates the first [[Cylons (RDM)|Cylons]] of the Twelve Colonies to aid in hard labor and warfare. A virtual copy of his dead monotheist daughter [[Zoe Graystone]]'s consciousness is downloaded into one ([[Caprica pilot]]). Humanity is unaware that they are repeating the actions of their ancestors on Kobol.
*'''ca. 58 BCH:'''
**[[William Adama]] born in [[Qualai]], [[Caprica (RDM)|Caprica]]. He is named for his deceased older brother. ([[Hero]], [[Apotheosis]]).
*'''52 years BCH:'''
**Cylon revolt starts the first [[Cylon War]] ([[Colonial Day]]).
**[[Articles of Colonization]] signed ([[Colonial Day]]).<ref>From Ronald D. Moore's [http://blog.scifi.com/battlestar/archives/2005/04/index.html#a000025 scifi.com blog post] of April 11, 2005: "Colonial Day occurs every year and it is the anniversary of the founding of the "federal" system of government which was a relatively recent event. Before that time, the Colonies functioned more or less on their own, possibly with various attempts at alliances or even complete Colonial government over the centuries since the exodus from Kobol, none of which were successful. When the first Cylons were created, individual Colonies still warred against one another and it wasn't until the Cylon rebellion that the 12 Colonies finally came together in a permanent way. Presumably, the Articles of Colonization were not made up out of whole cloth, however, and there may well be principles and ideas of justice that date back to the original colonists."</ref>
*'''51 years BCH:''' Colonial ship ''[[Brenik]]'' is lost after a boarding action by [[Cylon Centurion Model 0005|Cylon Centurions]] ([[Valley of Darkness]], deleted scene).
*'''ca. 50 years BCH:''' Battlestar ''[[Galactica (RDM)|Galactica]]'' enters service.
*'''42 years BCH:''' William Adama begins his service in the Colonial Fleet as a Viper pilot, near the end of the Cylon War ("Hero", [[Razor Flashbacks]]).
*'''40 years BCH:'''
**Mechanical Cylons begin experiments constructing humanoid forms of Cylon. They succeed in creating the [[First Hybrid]] and subsequent [[Hybrid]]s, but no fully humanoid forms.
**The Final Five arrive in the Colonial solar system in the waning days of the war.
**The Five meet the local Cylons and negotiate an end to the war. They will give the Cylons biological bodies complete with resurrection technology if the Cylons agree to end the war.
**[[Operation Raptor Talon]] conducted by the Colonial Fleet. Battlestar ''[[Columbia (RDM)|Columbia]]'' destroyed (Razor Flashbacks).
**Armistice ends the [[Cylon War]]. Cylons exile themselves from the Twelve Colonies ([[Miniseries]]). The First Hybrid and his [[Cylon Centurion Model 0005#Guardians|Guardians]] part company with the other Cylons.
**William Adama musters out of the Colonial Fleet ("[[Scattered]]", [[Sources:Adama's Dossier|Adama's dossier]]).
*'''37 BCH:''' William Adama enlists as merchant marine and serves aboard inter-colony freighters ("Scattered", Adama's dossier).
*'''37 to ca. 30 BCH:'''
** The Cylons establish a secret base known as [[The Colony]], built around and connected with the original ship of the Final Five. This is the place where research and development equipment belonging to the Final Five is stored.
**The Final Five create [[John Cavil]], the first of the new humanoid Cylons that are their "children," and designate him model Number One. They raise him for some time.
**John matures and assists the Final Five in the creation of seven other humanoid Cylon models. A resurrection system is built for the new models based on technology left over from the Thirteenth Tribe.
*'''ca. 30 BCH:'''

Colonial calendar

2011-01-15T16:33:12Z

Graf Iblis: /* Years */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is usually composed of the letters YR and a two-digit number. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. Some of the year formats are listed below (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

YR99 and lower [[Colonial calendar#Here Be Dragons|precede]] YR00. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 added] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! GREGORIAN MONTH !! ''CAPRICA'' MONTH !! DAYS PER MONTH ON ''CAPRICA''
|-
| January || Ianuarius || [[The Caprican#Ianuarius|at least 23]]
|-
| February || Februarius || [[The Caprican#Februarius|at least 27]]
|-
| March || Martius || [[The Caprican#Martius|at least 30]]
|-
| April || Aprilis || [[The Caprican#Aprilis|at least 24]]
|-
| May || Maius || [[Colonial calendar#Pyramid posters|at least 27]]
|-
| June || Iunius || [[Colonial calendar#Pyramid posters|at least 27]]
|-
| July || Quintilis || [[Colonial calendar#Pyramid posters|at least 25]]
|-
| August || Sextilis || [[Colonial calendar#The Imperfections of Memory|at least 14]]
|-
| September || September || [[Colonial calendar#Here Be Dragons|at least 23]]
|-
| October || October || [[The Caprican#October|at least 29]]
|-
| November || November || [[The Caprican#November|at least 16]]
|-
| December || December? || unknown
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but we have also seen what appear to be alternate names: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. In no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37
*SEPTEMBER 11, YR37

*Iunius 12, YR37 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR37.jpg|x20px]]

*MARTIUS 19, YR39
*MARTIUS 27, YR39
*MAIUS 22, YR39

*IUNIUS 5, YR39
*IUNIUS 27, YR39

*Quintilis 25, YR39 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR39.jpg|x20px]]

==Analysis of William Adama's Dossier==

In "[[Hero]]" [[William Adama]]'s [[:md:Image:Dossier.png|dossier]] can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Different Timekeeping Methods ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-15T13:59:30Z

Graf Iblis:

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is composed of YR and a two-digit number. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. The following formats have been seen (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

YR99 and lower [[Colonial calendar#Here Be Dragons|precede]] YR00. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 added] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! GREGORIAN MONTH !! ''CAPRICA'' MONTH !! DAYS PER MONTH ON ''CAPRICA''
|-
| January || Ianuarius || [[The Caprican#Ianuarius|at least 23]]
|-
| February || Februarius || [[The Caprican#Februarius|at least 27]]
|-
| March || Martius || [[The Caprican#Martius|at least 30]]
|-
| April || Aprilis || [[The Caprican#Aprilis|at least 24]]
|-
| May || Maius || [[Colonial calendar#Pyramid posters|at least 27]]
|-
| June || Iunius || [[Colonial calendar#Pyramid posters|at least 27]]
|-
| July || Quintilis || [[Colonial calendar#Pyramid posters|at least 25]]
|-
| August || Sextilis || [[Colonial calendar#The Imperfections of Memory|at least 14]]
|-
| September || September || [[Colonial calendar#Here Be Dragons|at least 23]]
|-
| October || October || [[The Caprican#October|at least 29]]
|-
| November || November || [[The Caprican#November|at least 16]]
|-
| December || December? || unknown
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but we have also seen what appear to be alternate names: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. In no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37
*SEPTEMBER 11, YR37

*Iunius 12, YR37 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR37.jpg|x20px]]

*MARTIUS 19, YR39
*MARTIUS 27, YR39
*MAIUS 22, YR39
*MAIUS 27, YR39
*IUNIUS 5, YR39
*IUNIUS 27, YR39

*Quintilis 25, YR39 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR39.jpg|x20px]]

==Analysis of William Adama's Dossier==

In "[[Hero]]" [[William Adama]]'s [[:md:Image:Dossier.png|dossier]] can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Different Timekeeping Methods ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Graf Iblis: /* The Calendar from Caprica */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced its own calendar system which is relatively
consistent and widely used on various props.

=== Years ===

The year is composed of YR and a two-digit number. Apart from its epilogue and flashbacks, ''Caprica'' is set in YR42 according to almost every source. The following formats have been seen (roughly in the order of frequency):

*YR01
*YR 01
*yr01
*01YR
*01

YR99 and lower [[Colonial calendar#Here Be Dragons|precede]] YR00. [[Serge#Links|SergeGraystone]] [http://twitter.com/SergeGraystone/status/14049746690 explained] that "YR means 'year' and 42 represents the last two digits of the year." When asked about the era, he [http://twitter.com/SergeGraystone/status/14206885187 added] that the present day is "1,942 years since the human exodus from [[Kobol (RDM)|Kobol]]." Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series.

=== Months ===

The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

{| class="messagebox"
|- class="infoboxheader"
! GREGORIAN MONTH !! ''CAPRICA'' MONTH !! DAYS PER MONTH ON ''CAPRICA''
|-
| January || Ianuarius || [[The Caprican#Ianuarius|at least 23]]
|-
| February || Februarius || [[The Caprican#Februarius|at least 27]]
|-
| March || Martius || [[The Caprican#Martius|at least 30]]
|-
| April || Aprilis || [[The Caprican#Aprilis|at least 24]]
|-
| May || Maius || [[Colonial calendar#Pyramid posters|at least 27]]
|-
| June || Iunius || [[Colonial calendar#Pyramid posters|at least 27]]
|-
| July || Quintilis || [[Colonial calendar#Pyramid posters|at least 25]]
|-
| August || Sextilis || [[Colonial calendar#The Imperfections of Memory|at least 14]]
|-
| September || September || [[Colonial calendar#Here Be Dragons|at least 23]]
|-
| October || October || [[The Caprican#October|at least 29]]
|-
| November || November || [[The Caprican#November|at least 16]]
|-
| December || December? || unknown
|}

The most frequent names are identical to those in the [[w:Roman calendar|Roman calendar]], but we have also seen what appear to be alternate names: Junius, June, Aprilus, Sextilius.

=== Date format ===

The date components can be formatted in many different ways. In no particular order:

*Sextilis 8, YR42
*8 Sextilis YR42
*08/08/yr42
*08-08-42YR
*08/08/42

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37
*SEPTEMBER 11, YR37

*Iunius 12, YR37 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR37.jpg|x20px]]

*MARTIUS 19, YR39
*MARTIUS 27, YR39
*MAIUS 22, YR39
*MAIUS 27, YR39
*IUNIUS 5, YR39
*IUNIUS 27, YR39

*Quintilis 25, YR39 ['YR' prefix with a smaller font size] [[Image:Pyramid_Finals_Poster_YR39.jpg|x20px]]

==Analysis of William Adama's Dossier==

In "[[Hero]]" [[William Adama]]'s [[:md:Image:Dossier.png|dossier]] can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Different Timekeeping Methods ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

Graf Iblis: /* Evidence from the series */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced a relatively prominent system in which the names of months are identical to those in the [[w:Roman calendar|Roman calendar]], while years are two-digit numbers almost invariably prefixed or suffixed with the letters 'YR'. The bulk of the series is set in YR42 according to a variety of sources, but the exact time within the year has been stated differently and therefore remains uncertain.

In response to a request for clarification, [[Serge#Links|SergeGraystone]] explained on his Twitter account that ''YR means "year" and 42 represents the last two digits of the year.''<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/14049746690 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-05-15}}</ref> When asked about the initial digits and the era, he replied that ''It has been 1,942 years since the human exodus from [[Kobol (RDM)|Kobol]].''<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/14206885187 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-05-17}}</ref> This interval had been stated on the Twitter account earlier, but only in connection with the age of the twelve worlds.<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/11953827897 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-04-10}}</ref> Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series. The calendar information could be accurate if the reply was based on the series bible or similar behind-the-scenes materials.

The same style of calendar is used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', although its timespans between events in the series are much longer than onscreen. Apparently, the blog's dates of YR42 were calculated by adding varying numbers of days to real-world posting dates, which are totally independent of story time. A comparison with the Roman calendar shows that Iunius (June) and Quintilis (July) were skipped during the initial three-month pause, which is consistent with the publication date of July 27 for the special article of Sextilis 4. September appears to have been skipped as well before regular publication continued.

Aside from showing Aprilis (in addition to Aprilus), Maius and Sextilis, the series has independently established Iunius (in addition to Junius). The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Unknown episodes====

*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37

==Analysis of William Adama's Dossier==

In "[[Hero]]" [[William Adama]]'s [[:md:Image:Dossier.png|dossier]] can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Different Timekeeping Methods ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-14T22:12:07Z

Graf Iblis: /* Evidence from the series */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced a relatively prominent system in which the names of months are identical to those in the [[w:Roman calendar|Roman calendar]], while years are two-digit numbers almost invariably prefixed or suffixed with the letters 'YR'. The bulk of the series is set in YR42 according to a variety of sources, but the exact time within the year has been stated differently and therefore remains uncertain.

In response to a request for clarification, [[Serge#Links|SergeGraystone]] explained on his Twitter account that ''YR means "year" and 42 represents the last two digits of the year.''<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/14049746690 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-05-15}}</ref> When asked about the initial digits and the era, he replied that ''It has been 1,942 years since the human exodus from [[Kobol (RDM)|Kobol]].''<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/14206885187 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-05-17}}</ref> This interval had been stated on the Twitter account earlier, but only in connection with the age of the twelve worlds.<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/11953827897 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-04-10}}</ref> Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series. The calendar information could be accurate if the reply was based on the series bible or similar behind-the-scenes materials.

The same style of calendar is used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', although its timespans between events in the series are much longer than onscreen. Apparently, the blog's dates of YR42 were calculated by adding varying numbers of days to real-world posting dates, which are totally independent of story time. A comparison with the Roman calendar shows that Iunius (June) and Quintilis (July) were skipped during the initial three-month pause, which is consistent with the publication date of July 27 for the special article of Sextilis 4. September appears to have been skipped as well before regular publication continued.

Aside from showing Aprilis (in addition to Aprilus), Maius and Sextilis, the series has independently established Iunius (in addition to Junius). The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

====Here Be Dragons====

*Joseph Adama ("Shay Ross Hilliard") was born on Sextilis 8, YR93 according to his falsified birth certificate, passport and driver's license. The latter uses the same format as Tad Thorean's, 08-08-93YR, confirming that Sextilis is indeed the eighth month. More importantly, YR93 doesn't contradict SergeGraystone's comment that YR is followed by the last two digits of the year. However, the driver's license was issued 04-01-43YR, which is inconsistent with the prevailing YR42 ([http://caprica.propworx.com/2011/01/12/video-featurette-joseph-adamas-falsified-passports-and-id/ Propworx auction]).

====Unknown episodes====

*A packet entitled ''U-87 Circuitry Specifications'' was "ISSUED 10 OCT." ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_U-87_Circuitry_Specifications_Packet.jpg|x20px]]

====Pyramid posters====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37

==Analysis of William Adama's Dossier==

In "[[Hero]]" [[William Adama]]'s [[:md:Image:Dossier.png|dossier]] can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Different Timekeeping Methods ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-14T19:07:43Z

Graf Iblis: /* Evidence from the series */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced a relatively prominent system in which the names of months are identical to those in the [[w:Roman calendar|Roman calendar]], while years are two-digit numbers almost invariably prefixed or suffixed with the letters 'YR'. The bulk of the series is set in YR42 according to a variety of sources, but the exact time within the year has been stated differently and therefore remains uncertain.

In response to a request for clarification, [[Serge#Links|SergeGraystone]] explained on his Twitter account that ''YR means "year" and 42 represents the last two digits of the year.''<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/14049746690 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-05-15}}</ref> When asked about the initial digits and the era, he replied that ''It has been 1,942 years since the human exodus from [[Kobol (RDM)|Kobol]].''<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/14206885187 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-05-17}}</ref> This interval had been stated on the Twitter account earlier, but only in connection with the age of the twelve worlds.<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/11953827897 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-04-10}}</ref> Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series. The calendar information could be accurate if the reply was based on the series bible or similar behind-the-scenes materials.

The same style of calendar is used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', although its timespans between events in the series are much longer than onscreen. Apparently, the blog's dates of YR42 were calculated by adding varying numbers of days to real-world posting dates, which are totally independent of story time. A comparison with the Roman calendar shows that Iunius (June) and Quintilis (July) were skipped during the initial three-month pause, which is consistent with the publication date of July 27 for the special article of Sextilis 4. September appears to have been skipped as well before regular publication continued.

Aside from showing Aprilis (in addition to Aprilus), Maius and Sextilis, the series has independently established Iunius (in addition to Junius). The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:

*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Apotheosis====

*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]). [[Image:Caprica Buccaneers Game Ticket Set.jpg|x20px]]

==Analysis of William Adama's Dossier==

In "[[Hero]]" [[William Adama]]'s [[:md:Image:Dossier.png|dossier]] can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Different Timekeeping Methods ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-14T18:53:17Z

Graf Iblis: /* Pyramid posters */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced a relatively prominent system in which the names of months are identical to those in the [[w:Roman calendar|Roman calendar]], while years are two-digit numbers almost invariably prefixed or suffixed with the letters 'YR'. The bulk of the series is set in YR42 according to a variety of sources, but the exact time within the year has been stated differently and therefore remains uncertain.

In response to a request for clarification, [[Serge#Links|SergeGraystone]] explained on his Twitter account that ''YR means "year" and 42 represents the last two digits of the year.''<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/14049746690 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-05-15}}</ref> When asked about the initial digits and the era, he replied that ''It has been 1,942 years since the human exodus from [[Kobol (RDM)|Kobol]].''<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/14206885187 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-05-17}}</ref> This interval had been stated on the Twitter account earlier, but only in connection with the age of the twelve worlds.<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/11953827897 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-04-10}}</ref> Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series. The calendar information could be accurate if the reply was based on the series bible or similar behind-the-scenes materials.

The same style of calendar is used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', although its timespans between events in the series are much longer than onscreen. Apparently, the blog's dates of YR42 were calculated by adding varying numbers of days to real-world posting dates, which are totally independent of story time. A comparison with the Roman calendar shows that Iunius (June) and Quintilis (July) were skipped during the initial three-month pause, which is consistent with the publication date of July 27 for the special article of Sextilis 4. September appears to have been skipped as well before regular publication continued.

Aside from showing Aprilis (in addition to Aprilus), Maius and Sextilis, the series has independently established Iunius (in addition to Junius). The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Apotheosis====


*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]).

==== Pyramid posters ====

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

==Analysis of William Adama's Dossier==

In "[[Hero]]" [[William Adama]]'s [[:md:Image:Dossier.png|dossier]] can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Different Timekeeping Methods ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-14T18:35:41Z

Graf Iblis: /* Rebirth */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced a relatively prominent system in which the names of months are identical to those in the [[w:Roman calendar|Roman calendar]], while years are two-digit numbers almost invariably prefixed or suffixed with the letters 'YR'. The bulk of the series is set in YR42 according to a variety of sources, but the exact time within the year has been stated differently and therefore remains uncertain.

In response to a request for clarification, [[Serge#Links|SergeGraystone]] explained on his Twitter account that ''YR means "year" and 42 represents the last two digits of the year.''<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/14049746690 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-05-15}}</ref> When asked about the initial digits and the era, he replied that ''It has been 1,942 years since the human exodus from [[Kobol (RDM)|Kobol]].''<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/14206885187 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-05-17}}</ref> This interval had been stated on the Twitter account earlier, but only in connection with the age of the twelve worlds.<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/11953827897 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-04-10}}</ref> Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series. The calendar information could be accurate if the reply was based on the series bible or similar behind-the-scenes materials.

The same style of calendar is used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', although its timespans between events in the series are much longer than onscreen. Apparently, the blog's dates of YR42 were calculated by adding varying numbers of days to real-world posting dates, which are totally independent of story time. A comparison with the Roman calendar shows that Iunius (June) and Quintilis (July) were skipped during the initial three-month pause, which is consistent with the publication date of July 27 for the special article of Sextilis 4. September appears to have been skipped as well before regular publication continued.

Aside from showing Aprilis (in addition to Aprilus), Maius and Sextilis, the series has independently established Iunius (in addition to Junius). The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====

*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Memorial_Event_Invitation.jpg|x20px]]

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Apotheosis====


*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]).

=== Pyramid posters ===

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37
*SEPTEMBER 11, YR37

==Analysis of William Adama's Dossier==

In "[[Hero]]" [[William Adama]]'s [[:md:Image:Dossier.png|dossier]] can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Different Timekeeping Methods ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

'''Gara Singh''' was the Director of the [[Caprica City]] bureau of the [[Caprica (RDM)|Caprican]] [[Global Defense Department]] in the years before the [[First Cylon War]].

==Investigating the STO==
Though Singh's GDD bureau had been saddled with mostly trivial cases, the bombing of the [[Metropolitan Levitation Mass Transit|Metropolitan Levitation Mass Transit System]] by monotheist [[Ben Stark]] and the resurgence of the [[Soldiers of the One]] terrorist group became Singh and his intestigators' primary focus ([[CAP]]: "[[The Reins of a Waterfall]]", "[[Gravedancing]]").

===Bombings===
Staying mostly on the sidelines as Agents [[Jordan Duram|Duram]] and [[Youngblood]] made inquiries into the bombing, Singh stepped in when he discovered a tape of the bomber, Stark, being interrogated by Youngblood one year before the bombing for possession of explosives. Singh suggested the tape be destroyed and Duram and Youngblood step up their game, inspiring a major break in the case ([[CAP]]: "[[The Reins of a Waterfall]]").

As the STO began bombing Holocafes throughout Caprica City, Singh was initially hesitant to attribute the crimes to a resurgence of the monotheist terrorists. However, when the [[Inter-Colonial Court]] on [[Libran]] handed down a warrant allowing the search of the [[Athena Academy]] - where Ben Stark and his suspected accomplice [[Zoe Graystone]] attended - Singh reluctantly allowed Agent Duram to proceed, telling him, though, to keep it "tasteful".

:''In scenes deleted from the episode "[[Know Thy Enemy]]", Agent Duram secures high tech equipment for the GDD office that would allow quick identification of potential suspects by searching the entire "Caprican Mesh". As a test group, Duram used members of the GDD, including his partner Youngblood and Director Singh, both of whom came up clean.

:''The storyline continued into scenes later omitted from "[[The Imperfections of Memory]]" in which Duram and the GDD installed cameras at [[Atlas Arena]] to scan faces in the stadium and pinpoint any possible STO members. Throughout this investigation, Singh is hesitant about the sidestepping of "certain liberties" apparently so easy for Agent Duram. Capturing and detaining a suspect, Duram expresses his disgust for the monotheist movement and Singh reins him.

===STO Murders===
Following the murder of two members of the STO who were also former students at Athena Academy, Agent Duram stepped up his investigation into the school's headmistress, Sister [[Clarice Willow]]. Having been alerted of accusations made to Willow by her lawyer, Director Singh once again interceded. Meeting with Duram away from the office, Singh admonished Duram for harassing Willow, telling him of that the [[Athena, Lord of Kobol|Athenian]] cleric could not be the monotheist terror leader Duram believed she was. Singh also emphasized that everyone at the GDD was invested in solving the murders ([[CAP]]: "[[Retribution]]").

===Revelations===
With growing suspicion that the STO had infiltrated the GDD, Agent Duram misdirected Director Singh with information falsely implicating [[Mar-Beth Willow]] - Clarice Willow's wife - as a confidential informant. Upon the sudden disappearance and apparent murder of Mar-Beth, Singh revealed himself to be the mole, funneling information about the investigation into the STO to Clarice Willow's cell under the alias "[[Alvo]]". As Alvo, Singh had also stolen evidence gathered from Zoe Graystone's belongings and given it Willow, a key element in her pursuit of [[Apotheosis]]. Despite this information, Duram declined to turn Singh in, lacking concrete evidence ([[CAP]]: "[[Blowback]]").

Aware of the threat Duram now posed to his position in the GDD, Singh altered video surveillance footage of a meeting with Duram, to make it appear as though the agent had become a rogue. Alerting Internal Affairs, Singh took Duram's badge and gun and removed him from the force, handing his caseload over to Agent Youngblood ([[CAP]]: "[[The Dirteaters]]").

Colonial calendar

2011-01-12T20:06:39Z

Graf Iblis: /* The Reins of a Waterfall */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced a relatively prominent system in which the names of months are identical to those in the [[w:Roman calendar|Roman calendar]], while years are two-digit numbers almost invariably prefixed or suffixed with the letters 'YR'. The bulk of the series is set in YR42 according to a variety of sources, but the exact time within the year has been stated differently and therefore remains uncertain.

In response to a request for clarification, [[Serge#Links|SergeGraystone]] explained on his Twitter account that ''YR means "year" and 42 represents the last two digits of the year.''<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/14049746690 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-05-15}}</ref> When asked about the initial digits and the era, he replied that ''It has been 1,942 years since the human exodus from [[Kobol (RDM)|Kobol]].''<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/14206885187 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-05-17}}</ref> This interval had been stated on the Twitter account earlier, but only in connection with the age of the twelve worlds.<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/11953827897 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-04-10}}</ref> Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series. The calendar information could be accurate if the reply was based on the series bible or similar behind-the-scenes materials.

The same style of calendar is used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', although its timespans between events in the series are much longer than onscreen. Apparently, the blog's dates of YR42 were calculated by adding varying numbers of days to real-world posting dates, which are totally independent of story time. A comparison with the Roman calendar shows that Iunius (June) and Quintilis (July) were skipped during the initial three-month pause, which is consistent with the publication date of July 27 for the special article of Sextilis 4. September appears to have been skipped as well before regular publication continued.

Aside from showing Aprilis (in addition to Aprilus), Maius and Sextilis, the series has independently established Iunius (in addition to Junius). The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====


*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]]).

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall]], [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Apotheosis====


*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]).

=== Pyramid posters ===

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37
*SEPTEMBER 11, YR37

==Analysis of William Adama's Dossier==

In "[[Hero]]" [[William Adama]]'s [[:md:Image:Dossier.png|dossier]] can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Different Timekeeping Methods ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.

Colonial calendar

2011-01-12T20:06:17Z

Graf Iblis: /* The Reins of a Waterfall */

:''This article presents timekeeping in the [[Battlestar Galactica (RDM)|re-imagined series]] and [[Caprica (series)|''Caprica'']]. For the specific chronology of events, see [[Timeline (RDM)]].''

The hypothetical '''Colonial calendar''' would be common to the Twelve Colonies, but aside from their use of units such as days, months and years, there is little information about a system from which the units would theoretically derive. We don't even know whether all the colonies use one method as opposed to individual, colony-based calendars.

Specific dates were usually avoided in the re-imagined series; the most detailed depiction of an actual calendar comes from the dossier of William Adama's career in the episode "[[Hero]]" (see [[Colonial calendar#Analysis of William Adama's Dossier|below]]). Dated props such as memos, awards, letters and similar items were photographed for various auctions, revealing styles of dates ranging from seemingly random alphanumerics to inconsistent year numbers. The diversity of dates strongly suggests that no definite system had been established for the re-imagined series.

On the other hand, the aired episodes of ''Caprica'' and the associated materials contain prominent and much more consistent references on the same kinds of items, indicating that the producers have settled on a system which is based on the Roman calendar. The method is also used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', which has revealed much of the basic calendar structure. However, since the series rarely takes us to other colonies, it remains unclear whether the calendar is specific to the planet [[Caprica (RDM)|Caprica]] or common to the twelve worlds.

==Units of Time==

The units used to express timespans in the re-imagined series and ''Caprica'' appear to be identical to those of the Gregorian calendar, with 24-hour days and approximately 365-day years. The best example of this is in "[[Tigh Me Up, Tigh Me Down]]," where Baltar says that each of his tests takes 11 hours. As there are 47,905 tests, amounting to 526,955 hours' worth of tests, this will take him 21,956 days or 60.1534 years (as confirmed by [[Number Six#Baltar's Messenger Six|Baltar's Messenger Six]]).

[[Image:Stormwatch.PNG|thumb|Weather forecast featuring all seven days of the week]]
Although the calculation uses an average year of 365 days, without taking into account leap years, it could be due to a mistake rather than a deliberate revision. A year comprising 52 weeks is revealed in "[[Rebirth]]" during the airing of a ''[[Cubits & Pieces]]'' clip. Further, days of the week are gradually introduced in this and later episodes: [[w:Saturday|Saturday]] ([[CAP]]: "[[Rebirth]]"), [[w:Monday|Monday]] ([[CAP]]: "[[Gravedancing]]") and [[w:Wednesday|Wednesday]] ([[CAP]]: "[[Ghosts in the Machine]]"). All seven days are finally shown onscreen as part of a weather forecast ([[CAP]]: "[[Retribution]]").

[[Ronald D. Moore]] addressed the units of time on his [http://web.archive.org/web/20080407195430/blogs.scifi.com/battlestar/2005/02/ blog]: "I dropped many other terms from the old show like '[[centon]]' (a unit of measurement) and '[[yahren]]' (year) because I felt they distracted from the mood I was trying to create and they sounded a bit silly to my ear." Nevertheless, the word ''yahren'' does appear in the [[Cylon Centurion Model 0005#Connection to the Original Series|Cylon specifications]] examined by the [[Armistice Officer]] ([[TRS]]: [[Miniseries, Night 1]]).

== The Calendar from ''Caprica'' ==

Maintaining consistency with the units described above, ''Caprica'' has introduced a relatively prominent system in which the names of months are identical to those in the [[w:Roman calendar|Roman calendar]], while years are two-digit numbers almost invariably prefixed or suffixed with the letters 'YR'. The bulk of the series is set in YR42 according to a variety of sources, but the exact time within the year has been stated differently and therefore remains uncertain.

In response to a request for clarification, [[Serge#Links|SergeGraystone]] explained on his Twitter account that ''YR means "year" and 42 represents the last two digits of the year.''<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/14049746690 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-05-15}}</ref> When asked about the initial digits and the era, he replied that ''It has been 1,942 years since the human exodus from [[Kobol (RDM)|Kobol]].''<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/14206885187 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-05-17}}</ref> This interval had been stated on the Twitter account earlier, but only in connection with the age of the twelve worlds.<ref>{{cite web|url=http://twitter.com/SergeGraystone/status/11953827897 |title=Serge Graystone (SergeGraystone) on Twitter |date=2010-04-10}}</ref> Adding the 58 years between the pilot and the ''Battlestar Galactica'' miniseries results in a timespan of precisely 2,000 years, consistent with approximate time references from the re-imagined series. The calendar information could be accurate if the reply was based on the series bible or similar behind-the-scenes materials.

The same style of calendar is used in the [[Syfy]] blog ''[[The Caprican#Out of Universe|The Caprican]]'', although its timespans between events in the series are much longer than onscreen. Apparently, the blog's dates of YR42 were calculated by adding varying numbers of days to real-world posting dates, which are totally independent of story time. A comparison with the Roman calendar shows that Iunius (June) and Quintilis (July) were skipped during the initial three-month pause, which is consistent with the publication date of July 27 for the special article of Sextilis 4. September appears to have been skipped as well before regular publication continued.

Aside from showing Aprilis (in addition to Aprilus), Maius and Sextilis, the series has independently established Iunius (in addition to Junius). The table below collates months and days per month from all sources, matching them to the Gregorian calendar.

=== Evidence from the series ===

====Revised ''Caprica'' pilot====

*A scrolling digital announcement in the [[Atlas Arena]] reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Caprica pilot#Differences between the DVD and TV Cut|Revised ''Caprica'' pilot]]).

====Rebirth====


*The [[Lev]] bombing memorial event was scheduled for "Junius 7th, Mid-Day" according to [[Joseph Adama]]'s invitation ([[Rebirth]]).

====The Reins of a Waterfall====

*The recording of [[Ben Stark]]'s interrogation is dated "APRILUS 9TH YR41". Agent [[Jordan Duram]] says that it was made a year ago.
*Moments later, Duram looks at what appears to be the current issue of ''Caprican Tribune'', which is dated "Aprilis 11, YR 42". Although illegible onscreen, "November 26" is given as the MagLev bombing date ([[The Reins of a Waterfall, [http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune_Hero_Newspaper.jpg|x20px]]

====Gravedancing====

*[[Daniel Graystone]] says he made a Solstice wish for free publicity, referencing [[Baxter Sarno]]'s previous coverage of the Graystone family ([[Gravedancing]]). Since ''The Caprican'' has placed the [http://showblogs.syfy.com/caprican/entertainment/argentum-bay-the-ultimate-vernal-break.php Vernal Break] in Martius, analogous to the vernal equinox in March on Earth, Daniel's line could be taken as supporting evidence for the Junius timeframe from "[[Rebirth]]". Solstices on Earth occur around June 21 and December 22.
*Ross Farmo's staff badge on ''[[Backtalk with Baxter Sarno]]'' contains the note "EXP. 08 YR 44". The badge apparently expires in Sextilis YR44 ([http://caprica.propworx.com/2011/01/11/how-about-some-backtalk-from-caprica/ Propworx auction]). [[Image:Caprica_Baxter_Sarno_Staff_Badge.jpg|x20px]]

====Know Thy Enemy====

*Joseph Adama asks [[Evelyn]] to identify [[Tad Thorean]] based on black-and-white photographs with timestamps, where the date component almost certainly reads "YR:42:02:22".
*Tad Thorean's date of birth is given as "06-04-27YR" on his driver's license, which also contains less readable dates of issue and expiration ([[Know Thy Enemy]]).

====The Imperfections of Memory====

*The [[Delphi Convalescent Institute]] logo includes the following text on their letter to [[Amanda Graystone]]: "Established YR 01". The date is also [http://showblogs.syfy.com/caprican/news/delphi-institute-loses-major-funding.php mentioned] in ''The Caprican''.
*Amanda shows [[Clarice Willow]] the museum poster advertising the ''Impressions'' exhibition. According to the text on the bottom, it lasts from "MAIUS 11 TO SEXTILIS 14, YR42" ([[The Imperfections of Memory]]). Sextilis was originally the sixth month in the Roman calendar and was later renamed Augustus in honor of Augustus Caesar.

====Ghosts in the Machine====

*[[Tamara Adama]]'s signature is found near a poster opposite the gun check-in booth in the virtual club visited by Joseph Adama and [[Emmanuelle]]. The poster promotes an event "Exclusive to The Eleusinian Theatre Throughout the month Of Maius" ([[Ghosts in the Machine]]).

====End of Line====

*The deadline for Daniel Graystone to deliver 100,000 robots was moved up to "the seventh", which is "next week". We don't know if this is a day of a month, but it could become significant should we obtain more information ([[End of Line]]). The episode also establishes the existence of a holiday named [[Eros Day]], which was first mentioned in articles of ''The Caprican'' posted in February 2010, a month before the episode aired, and is a clear parallel to St. Valentine's Day.

====Retribution====

*Daniel Graystone, Joseph and [[Sam Adama]] review [[Lillian Teller]]'s personnel file which contains "7 Iunius YR 38" as the "start" date, presumably for when she started as director. In addition, a less readable year is briefly shown in the previous employment section of the document ([[Retribution]]).

====Things We Lock Away====

*The [[U-87]] file reviewed by [[Tomas Vergis]] was "ISSUED 11 SEXTILIUS" ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]). [[Image:Caprica_Vergis_Hero_U-87_File.jpg|x20px]]

====False Labor====

[[Image:Caprica_Duram's_Hero_Files.jpg|thumb|Duram's files.]]
*Duram's files contain a number of dates which aren't fully legible at this point. From the document on Clarice Willow:
**"PRINT DATE" (?) "09/26/yr42" (?)
**"FILE DATE" (?) "09/27/yr42" (?)
**"BORN" (?) "01-28-YR04" (?) (her age is given as 37)
**"Year Grad" (university?) "29YR" (?)
*An included photo appears to point out the place where Hippolyta (?) Androgeus' ([[Hippolyta]]'s?) corpse was found. The numbers "23/09/42" are associated with the circled location. Although 'YR' is missing, the figures are consistent with the first two dates in Willow's file ([http://caprica.propworx.com/2011/01/05/so-much-for-a-paperless-society/ Propworx auction]).
*An edition of ''Caprican Tribune'' was published on "JUNE 28, YR42" ([http://caprica.propworx.com/ Propworx auction]). [[Image:Caprica_Caprican_Tribune.jpg|x20px]]

====Blowback====

*Various boxes in the [[Global Defense Department]] evidence room are labeled "YR41" or "YR42" ([[Blowback]]).

====Apotheosis====


*Daniel pronounces his access code as "Wye-Ar-25-Zeta-Theta-Epsilon", where the Greek letters spell out ΖΘΕ. If YR25 is [[Zoe Graystone]]'s year of birth, she would've celebrated her seventeenth birthday in YR42.
*A scrolling digital announcement in the Atlas Arena reads "BE HERE FOR THE NEXT HOME GAME ON IUNIUS 27TH!" ([[Apotheosis]]). Since the exact same text was also used in the pilot and we've seen several games in the meantime, it probably shouldn't be taken literally.
*Tickets to the [[Caprica Buccaneers]] vs. [[Pyramid_(RDM)#Pre-Cylon_War|Delphi Legion]] game are dated "SEXTILIS 11, YR42" ([http://caprica.propworx.com/2011/01/04/caprica-buccaneers-fan-paraphernalia/ Propworx auction]).

=== Pyramid posters ===

[[Image:Pyramid_Playoffs_Poster_YR37.jpg|thumb|YR37 pyramid playoffs.]]
[[Image:Pyramid_Playoffs_Poster_YR39.jpg|thumb|YR39 pyramid playoffs.]]
An [http://www.profilesinhistory.com/items/hollywood-memorabilia-auction-42/four-pyramid-playoffs-posters-from-eric-stoltz-daniel-graystones-private-game-box-in-caprica.html auction] of four posters from Daniel's private game box revealed a number of playoff dates, confirming the months of Quintilis and September. In some of the layouts, the 'YR' prefix is written with a smaller font size than the rest of the date, indicating a possible stylistic alternative.

*APRILIS 6, YR37
*APRILIS 11, YR37
*QUINTILIS 3, YR37
*QUINTILIS 22, YR37
*SEPTEMBER 4, YR37
*SEPTEMBER 11, YR37

==Analysis of William Adama's Dossier==

In "[[Hero]]" [[William Adama]]'s [[:md:Image:Dossier.png|dossier]] can be clearly seen. While this document is fairly accurate in terms of Adama's personal history, the calendar scheme used in the document seems to be flawed, particularly in lieu of previously established methods of timekeeping demonstrated in the series.

Here are a list of dates from Adama's past that Adama's dossier contains:

:H5/21290 Birth of William Adama
:D6/21311 First commission, Battlestar Galactica, fighter squadron
:E4/21312 Commendation for shooting down Cylon fighter in first combat mission.
:D5/21314 Mustered out of service post-armistice
:R6/21317 Served as Deck Hand in merchant fleet and as common […] aboard inter-colony tramp freighters
:D1/21331 Recomissioned to Fleet
:D6/21337 Major: Battlestar ''[[Atlantia (RDM)|Atlantia]]''
:R8/21341 Executive Officer: Battlestar ''[[Columbia (RDM)|Columbia]]''
:C2/21345 Commander: Battlestar ''[[Valkyrie]]''
:C2/21348 Commander: Battlestar ''Galactica''

This provides some interesting information. The fields in the format X#/##### appear to be dates, with the five-digit string following the solidus apparently corresponding to the year.

The following can be deduced from this document:

* This episode marks the 45th anniversary of Adama's commissioning, which puts it in the year 21356 and makes Adama 66 years old. On the other hand, he was born at least several months after the [[Caprica pilot]], which is set in 58 BCH ([[Apotheosis]]).
* Adama spent three years in between being mustered out and finding a job on a tramp freighter. We may speculate that it was during this time that his relationship with first wife [[Carolanne Adama]] deteriorated.
* Adama spent a total of 14 years serving in the merchant fleet.
* Adama met Tigh roughly 30 years ago ([[Torn]]). That would be 21326, which correctly puts it in the middle of Adama's merchant fleet service.
* Adama was a major by the time he arranged for Tigh to be reinstated in the fleet ([[Scattered]]), which means that at least six years passed in between Adama's recomissioning and Tigh's.
* Ronald Moore stated in his [[Podcast:Scattered|podcast for "Scattered"]] that the flashback scenes in [[Scattered|that episode]] took place 20 years before that episode, or in 21334. In fact, they appear to span at least an eleven-year period between 21326 (Adama and Tigh's first meeting) to 21337 (Adama's promotion to Major).
* The first [[Colonial Day (holiday)|Colonial Day]], marking the unification of the Colonies, was probably in 21302. The one celebrated in "[[Colonial Day]]" was the 52nd, and it is now two years later.
* ''Galactica'' herself is at least 45 years old. Other battlestar's minimum ages prior to the Fall: ''Atlantia'' at least 13, ''Columbia'' at least 11, and ''Valkyrie'' at least 8.

Additionally, an error occurs in "Hero". Dialogue from this episode claims that Adama served on ''Valkyrie'' one year prior to the [[Fall of the Twelve Colonies]], putting the date of Lt. [[Daniel Novacek|Daniel "Bulldog" Novacek]]'s capture at 21352-53. However, Adama's command of ''Valkyrie'' ended in 21348, which means that Adama commanded ''Galactica'' for eight years. It has already been established in dialogue from the [[Miniseries]], "[[Act of Contrition]]", and "[[The Farm]]".

=== Inference about calendar structure ===

If the five-digit string following the solidus is in fact the year, as seems inescapable based on the above, the letter-digit sequence before it must indicate the position in the year. There are 260 unique letter-digit sequences of that format, which may indicate a shorter year in the calendar, essentially a year of twenty-six ten-day weeks. However, what has been revealed about Colonial timekeeping is too incomplete to draw any conclusions.

However, if the above is to be inferred, a striking inaccuracy occurs because of this service record. Prior episodes have firmly established that the Colonial year is analogous to one Earth year of 365 days. In "[[Tigh Me Up, Tigh Me Down]]", the [[Cylon detector]] takes 11 hours to thoroughly test each blood sample. As there are 47,905 tests (526,955 hours) this will take him 21,956 days, which Six then computes will take approximately 60 years, the same as it would here. The timespans further established in "[[Lay Down Your Burdens, Part II]]", "[[Battlestar Galactica: The Resistance]]", and "[[Occupation]]" also support this comparison.

On the other hand, the Colonial numerical system may start with the numbers zero through 99, then continue with A1 through Z9, followed by AA, AB and so on. This would mean that the first day of the year is 1 and the last day, the 365th, is represented as AF.

It is astonishing to learn that the Colonials have -- or believe they have -- over 21,000 years of recorded history. By comparison, Pythia was said to have recorded her prophecies 3,600 years ago ([[The Hand of God (RDM)|The Hand of God]]) and the Great Exodus from [[Kobol (RDM)|Kobol]] took place just 2,000 years ago. On [[Earth (RDM)|Earth]], Human civilization is only about 6,000 years old.

== Different Timekeeping Methods ==

The system used in the dossier is only the most prominent example of dates in the re-imagined series. A closer analysis of other items reveals a number of different methods. It is unclear whether these were actual calendar proposals or random alphanumerics which were never intended for closer inspection.

*The note "SEVENTH MILLENNIUM OF TIME" appears on [http://www.battlestarprops.com/category/props/page/6/ paper cubits]. It comes from [[Adar (TOS)|President Adar]]'s toast in the [[Saga of a Star World|original series pilot]]: "As we approach the seventh millennium of time, the human race at last will find peace, thanks to you."
*[[Lee Adama]]'s date of birth is "432:979:021" according to his [http://www.battlestarprops.com/all-about-lee/ service record].
*William Adama was "to report to Aerilon High Command, Base 12 at 038:847:857" in his [http://www.battlestarprops.com/adamas-reinstatement-letter/ letter of reinstatement] in the Colonial Fleet. His shuttle was scheduled to leave for [[Aerilon]] "at 024:639:374".
*The [http://archive.propworx.com/1002/75 incident report] on the murder of [[Jack Fisk]] is dated "134-2367". The text contains references which appear to be dates: "On 25372- sometime after a meeting with President [[Laura Roslin]] ... Commander Jack Fisk returned to his quarters ... At approximately 24367-47 Officer [[Louis Hoshi|Hoshi]], after mustering his officers for their daily briefing, proceeded to Commander Fisk's quarters ..."
*Gaius Baltar's [http://www.battlestarprops.com/new-caprica-colonization-executive-order/ executive order] concerning settlement on [[New Caprica]] became law "this 23rd day of 04859".
*Baltar's [http://archive.propworx.com/1004/37 Proclamation of Illegal Arms] is dated "R767-87", and the exact same date also appears on the [http://archive.propworx.com/1004/41 Acquisition of Firearms for the New Caprica Police Academy] memo.
*Adama's [http://www.flickr.com/photos/48889053444@N01/3207207593 resignation letter] at the end of the [[Hero]] appears to be dated in an entirely different format compared to the system used in his dossier. While difficult to read clearly, it appears to be dated "27/S9/9F23". On the other hand this may not be a date but some form of document ID number.
*In addition, [[:md:Image:Execution Order Signature.png|the execution order]] written by the [[Cylon Occupation Authority]] and signed by then-President Gaius Baltar is dated "this second day of 3454-91" ([[Occupation]]). This may be a date on the Cylon Calendar but this would not explain why the Cylons wanted this "official" document to use their timekeeping system instead of that used by the Colonials.
*[[Kara Thrace]]'s [[:md:Image:Kara Thrace Record 1.jpg|disciplinary record]] in "[[Maelstrom]]" notes that a proceeding was "held on 22/E4/3F3". This appears to be a date, but there is no confirmation.
*The [http://www.battlestarprops.com/medal-of-valor/ medal of valor] given to [[Socrata Thrace]] uses a day number and alphanumerics to specify the current date ("this ...th day of ..."), whereas Socrata's period of service is expressed using two sets of alphanumerics. The exact numbers and letters are currently unreadable.
*A store sign in [[New Cap City]] reads "QUALITY JEWELRY SINCE 1952" ([[The Imperfections of Memory]]). It is unclear whether the year is related to the calendar from ''Caprica'', especially if SergeGraystone's 1,942-year era is correct.
