Timeline of galactic history/Legends

Fans of the Star Wars universe keep track of the dates of key events with a dating system (or calendar) centered around the Battle of Yavin featured in A New Hope. BBY stands for Before Battle of Yavin, and ABY stands for After Battle of Yavin. (Occasionally, the defeat of the Empire at the Battle of Endor [4 years after Yavin] has been used as an alternate starting year, but has generally been phased out in favor of the current standard system).

(Note: In-universe, this dating system is used almost exclusively by the Rebel Alliance/New Republic. The earlier Galactic Empire preferred to date events from the Great Resynchronization of 35 BBY, or from the Emperor's ascension to the throne (19 BBY). The Galactic Republic dated years from the Ruusan Reformation of 1,000 BBY.)

A galactic standard year, based on the length of a year on the Coruscant Standard Calendar, is 368 standard days, one standard day being a day of equal length as a day on Coruscant (twenty-four hours). (A Newtonian rather than General relativity space-time is presupposed, so that over a given interval a single duration of time passes at all locations equally.)
