SAGA- Shadow Republic
By the calendar of the Star Wars trilogy the events of this campaign take place in the year 3940 BBY (Before the Battle of Yavin). Since the battle of Yavin hasn’t happened yet, the Calendar for the game goes by the Coruscant Standard Calendar, which began in the year of the founding of the Republic.
The Republic was founded 25,013 years before the Battle of Yavin. Since the founding of the Republic the calendar has been reset several times to commemorate major events. Most recently the calendar was reset at the end of the Great Sith War, which happened in 3996, 54 years ago. The current calendar date is therefore 54 GSW.
