Part of the series on Timelines of the Battlestar Galactica series

Original Series Separate Continuities Richard Hatch's Continuation Other Comic Books and Novelizations Galactica 1980 Re-imagined Series Caprica Season 1 Season 2 Season 3 Season 4

The timeline below chronicles the events depicted in the Original Series, as well as the events that occurred in the various separate continuity sources.

The timeline for the Berkley novelizations does include elements from the spin-off series Galactica 1980, because of the Galactica Discovers Earth novelization.

The timeline is given in yahrens, the Colonial term for "years." The date around which the timeline revolves is 7322, the only date given in the series, and one from the Colonial calendar. This was the yahren when the Cylons attacked Umbra on Caprica, as mentioned in "The Man with Nine Lives".

Maximum Press comics

In War of Eden 2, Rob Liefeld noted that Maximum Press follows the established canon of the Original Series, eschewing Galactica 1980. Therefore, the timeline of the Original Series' episodes is included here, interspersed with data from the comics. It is later noted in the timeline printed in Starbuck 1 admits to using the Encyclopedia Galactica reference.

The acronym "CY" is for the term "Colonial Yahren", which appears in the Maximum Press comics.
