Endor Day served as a day of remembrance for the New Republic. It took place each year on the anniversary of the Battle of Endor in 4 ABY, honoring the triumph of the Alliance to Restore the Republic against the Galactic Empire.
As an easter egg, Star Wars Battlefront: Renegade Squadron features unique accolades for achieving top scores on leaderboards during actual holidays. Wookiee Life Day is represented as Christmas, while Endor Day is represented as the Fourth of July.
