Season 1

Note: Roslin states that the chair will remain open for nominations for 72 hours on the morning of Day 47, but the next episode clearly takes place the day after the victory party, and is stated to take place on Day 50. Perhaps the Quorum moved to close the nomination period early after the nomination of a strong candidate.

Season two timeline discontinuity

Main article: Season two timeline discontinuity

Based on various evidence, the end of "Resistance" can be very firmly dated to Day 54. This puts Cally's release at Day 84, and in turn means that as of "Flight of the Phoenix", Roslin was not expected to live past day 114. Corroborating this, Sharon Valerii does not appear visibly pregnant in "Pegasus".

However, in the following episode, Admiral Cain states offhandedly that it has been about six months since the fall of the colonies. This is further corroborated in "Epiphanies", which we learn takes place 189 days after the holocaust (a full 75 days longer than Roslin's most favorable prognosis). Additionally, Valerii now appears to be well into her second trimester, and elections have been put off by 75 days from their first-season projections.

There is apparently no way to reconcile this discrepancy. Even under the most liberal assumptions, the first half of the second season timeline cannot accommodate more than about three additional days.

Consequently, there is a 75-day discontinuity between the fist and second halves of season two. The second half of the season is dated from the firm dates given in "Resurrection Ship, Part I" and "Epiphanies", but be aware that dates throughout the remainder of season 2 are likely to contradict those from earlier in the series.

Season 2.5

Dates not specific to episodes

• c. Day ~140: Cylon Raiders attack the freighter Greenleaf (Sacrifice).

Resurrection Ship, Part I

• Day ~175 - The standoff between the two battlestars ends in an uneasy truce, and a tense summit aboard Colonial One, after Lt. Thrace returns from an unauthorized surveillance mission to the Cylon fleet, where she gains critical evidence on a Cylon ship. Dr. Baltar is able to determine from Gina that this is the Resurrection Ship that cylons need to resurrect so far from the Cylon homeworld.

Resurrection Ship, Part II

• Day ~177 - The Battlestars Galactica and Pegasus together engage the Cylon fleet in the Battle of the Resurrection Ship, where they achieve an overwhelming victory with relatively light casualties, destroying not only the Resurrection Ship, but at least one other Cylon base star. The Blackbird is destroyed in the battle, although Lee Adama manages to eject successfully. At least one Raptor is also lost in the battle. Admiral Cain is killed by Gina, after Baltar helps her escape captivity. He then proceeds to hide her in the fleet.

Epiphanies

• Day 189 - President Roslin near death; orders death of Cylon fetus. A Cylon peace movement begins to pose as a threat to the Fleet. The Cylon fetus is eventually spared, when Dr. Baltar determines how to use Cylon fetal stem cells to treat Roslin's cancer. Dr. Baltar smuggles the nuclear weapon that he was provided with for work on his Cylon detector to the Cylon peace movement aboard Cloud Nine.

Black Market

• Day ??? - Commander Fisk is murdered aboard the Battlestar Pegasus. Lee Adama begins an investigation into the matter.

Attacks on the operation continue by the ace Cylon raider known as Scar, making it the source of a heated competition between Lt. Katraine and Cpt. Thrace.

Sacrifice

• c. Day 210 - Three men and a woman named Sesha Abinell lay siege to bar onboard Cloud 9, taking the guests hostage, and sealing the area off from the rest of the ship. Abinell's husband was killed aboard the Greenleaf when the Cylons attacked it ten weeks ago, and she decides to exact vengeance. Lee Adama is wounded as a result of a failed rescue attempt by Kara Thrace

Backdated from "The Captain's Hand" and "Lay Down Your Burdens, Part I"

The Captain's Hand

• c. Day 236 - Kara Thrace assigned to Pegasus as flight instructor.
• Day ?? - Almost one month after the events of "Sacrifice", Lee Adama has been promoted to Major and temporarily assigned to Pegasus. Rya Kibby arrives on Galactica seeking a clandestine abortion from Dr. Cottle and requests asylum.
• c. Day 240 - Pegasus Commander Barry Garner dies during the Battle of the Binary Star System. Adama is promoted to Commander and given command of Pegasus, with Thrace replacing him as CAG of Galactica. In response to heavy lobbying from Gemenon delegate Sarah Porter over the Kibby incident, Roslin places a moratorium on abortion. In protest, Vice President Gaius Baltar announces his candidacy for president in the upcoming election.

Backdated from "Lay Down Your Burdens, Part I".

Downloaded

• Day 270 (Zero Hour + 9 months) - Hera born. This episode claims that the previous episode "Resistance" took place "10 weeks before" Day 270. However, 10x7 = 70 and 270 - 70 = 200, this would put Cally's shooting of Galactica-Boomer after "Epiphanies" which was stated to take place on Day 189. Even a very liberal estimate could not possibly place "Resistance" more than a week or two after "Kobol's Last Gleaming, Part II", when it was stated on screen that it was Day 51. This reference to "10 weeks" is a mistake, which will be corrected in the DVD and international releases of "Downloaded".

Lay Down Your Burdens, Part I

• c. Day 256 - Galen Tyrol begins a series of recurring suicidal nightmares.
• c. Day 269 - Presidential debates begin. Kara Thrace, Felix Gaeta and Lee Adama brief pilots on Caprica SAR mission on Pegasus. Tyrol attacks Cally after being woken from a nightmare.
• c. Day 270 - Media reports on first debates. SAR team departs; Margaret "Racetrack" Edmondson and crew accidentally discover a habitable planet and return to the Fleet. Tyrol begins counseling with Brother Cavil.
• c. Day 280 - Final presidential debate. SAR team arrives at Caprica and meets with Samuel Anders's Resistance.
• c. Day 283 - Polls open (projected).

Tom Zarek states that the fleet has been "cooped up in metal boxes for nine months" the morning after the debates. This date is roughly taken as Day 270, with an implied give-or-take of a couple weeks. The surrounding events noted above can, however, be placed relative to this point with a good degree of certainty based on episode dialogue.

Lay Down Your Burdens, Part II

• Day 281 - Thrace's SAR team and Anders' resistance are pinned down by a Cylon sneak attack. They are under siege for 18 hours, the next morning they awake to find the Cylons have completely abandoned Caprica.
• Day 282 - The SAR mission returns to Galactica, Cavil is discovered to be a Cylon when a second copy steps off a Raptor.
• Day 283 - The polls open, Baltar wins. Tory Foster conspires with Col. Tigh and Dualla to rig the vote results to keep Roslin in power. Their plan is found out by Lt. Gaeta and Admiral Adama convinces Roslin to let the people's will prevail and let Baltar become president.
• Day 284 - Baltar is inaugurated President. A distraught and emotionally bankrupt Gina detonates the nuclear warhead given to her by Baltar and destroys Cloud 9 and several other near-by ships.
• c. Day 285 - Adama visits President Baltar aboard Colonial One and questions him about the Cloud 9 disaster. A defiant Baltar rebukes all his questions and accusations.
• Between c. Day 285 and 660 - The fleet settles on New Caprica. Kara Thrace and Samuel Anders marry. Galen Tyrol and Cally marry, Cally becomes pregnant, Tyrol becomes a union head. Dualla transfers to Pegasus. Most of Galactica and Pegasus crews retire from active military duty. Dualla becomes Lee Adama's Tactical Officer on Pegasus. Felix Gaeta retires from military duty and becomes President Baltar's aide, Karl Agathon replaces him in the CIC. Former President Laura Roslin becomes a school teacher on New Caprica, Maya, Hera's adoptive mother, is her teacher's assistant. Lee Adama and Kara Thrace have fallen out of favour with one another, while Thrace and Col. Tigh appear to have mended fences.
• c. Day 660 - Admiral Adama discharges Col. Tigh from his duties aboard Galactica. Tyrol and Cally organize a general labor strike in protest of Baltar's poor leadership as President. Cylon forces occupy New Caprica.

Prior to Season 3.0

Battlestar Galactica: The Resistance

• Day 727 - Evening: - It has been 67 days since the Cylons occupied New Caprica. Tyrol and Tigh have been organizing a budding resistance movement, but they find recruiting new soldiers is becoming dangerous and difficult. New Capricans are shot on the spot if weapons are found in their tents. The Cylons are also setting up a human police force to take over for the Cylon Centurions, who are doing most of the police work.

• Day 728?: - Due to personal reasons Duck has refused to work with the resistance, much to the ire of Tyrol. A ritual for protection of the crops from blight is said in the temple. As the priestess leaves, Jean Barolay abruptly shifts the conversation to the movement of the weapons stash into the temple; Jammer strongly objects, but he is overruled by Tigh.

Future Events

• Day 86 + 1 month (c. Day 116): Roslin's maximum life expectancy as of Day 86 (Flight of the Phoenix)
• Day 54 + 3 months (c. Day 144): Samuel Anders's Caprica Resistance's anti-radiation med supply projected to run out (Resistance).
  • Anders' group survives in "Downloaded", c. Day 270. They could have simply found more stockpiles of anti-radiation meds in the intervening time period.
• Day 12 + 7 Months (c. Day 222): Elections due for President of the Twelve Colonies (Bastille Day).
  • As of "Downloaded", c. Day 270, the elections are near but have not yet arrived.
    • The elections come and go. Baltar is elected President (Lay Down Your Burdens, Part I and Part II).
• Day 50 + 6 Months (c. Day 230): Roslin's maximum life expectancy as of Day 50 (Kobol's Last Gleaming, Part I).
  • Roslin promised to get the fleet to Earth before her death (c. Day 230) (Fragged).
    • As of Day 660 Roslin is still alive and the fleet has not made it to Earth yet (Lay Down Your Burdens, Part II).
• Day 24 + 9 Months (c. Day 294): "Caprica" Sharon Valerii's daughter born. (see Notes below)
  • Hera, daughter of Helo and "Caprica" Sharon Valerii was born premature c. Day 270 (Downloaded).
• Day 36 + 3 years (c. Day 1131): Fleet runs out of tylium fuel that was resupplied from the Cylon asteroid mine; assuming that no other sources have been found before this date. (The Hand of God)
• Day 260 (approx) + 18 years (c. Day 6,830) Time at which, if the Survivor count keeps up its current rate of decline and never increases, the human race will simply go extinct, according to Baltar's estimate in "The Captain's Hand".
  • Due to the destruction of Cloud 9 and surrounding ships in "Lay Down Your Burdens, Part II", this figure has been drastically altered.

Notes

• The above day listings use a simplistic calendar system with 30 day months and no leap years. The colonial calendar may be more sophisticated.
• The date of Valerii and Agathon's child is speculated, assuming that the Cylon agents share the same gestation period that humans do, and that the birth of their hybrid daughter is not premature.
  • Date of Hera's birth is now confirmed at Day 270.
• Later episodes in "Season 2.5" such as "Resurrection Ship, Part I" and "Epiphanies" state clearly that "Pegasus" and the episodes immediately following it take place six months after the Cylon Attack. Ron D. Moore did state that it took Tyrol "weeks" to construct the Blackbird and a large amount of time passes in this episode as a result. BattlestarWiki originally assumed this meant at most 2-4 weeks. However, the only plausible way that Pegasus and Resurrection Ship, Part I can take place six months after the attack is if "Flight of the Phoenix" actually lasted three months from beginning to end. Roslin was told in this episode that her cancer had accelerated, and she had only one month to live. As Cally's "welcome back" party happened earlier in the episode, when she was released from the brig around Day 86, a considerable period of time (several weeks at least) pass between these two scenes.
