Galactic Timeline for Star Wars: The Old Republic. The Galactic Calendar is the in-universe calendar system adopted by the Galactic Senate following the Treaty of Coruscant (BTC/ATC).
Note: Most Information was obtained from Wookiepedia.
The Current Year is 3630 BBY / 23 ATC
>> Dates and events listed after 13 ATC are based on speculation+ five years for Knights of the Fallen Empire.<<
Further Evidence to Current Year
According to the novel The Old Republic: Annihilation, the Treaty of Coruscant collapsed in 3642 BBY, and Star Wars: The Old Republic: Knights of the Fallen Empire states that Choza Raabat disappeared two years before that, or 3644 BBY. The game also establishes that Raabat's disappearance occurred twelve years before the events of Fallen Empire, so Fallen Empire must take place in 3632 BBY, and Chapter I—which takes place five years prior to the rest of the expansion—in 3637 BBY.
The Galactic Standard Calendar is the standard calendar system used to reference all of Star Wars. It's based on the Battle of Yavin(BBY/ABY) from Star Wars Episode IV: A New Hope and the destruction of the first Death Star during the Galactic Civil War.
