The Star Wars universe and these events are clearly defined in time. You only have to look during the game, the time references and the notion of passing time are not absent.
However, in addition to the already official events, a number of authors have added their fictions to this list, which are also part of the chronology of the universe. If the Star Wars reference date is the Battle of Yavin IV (and the destruction of the first Death Star) as year 0, for this timeline we will take 0 as the year of the signing of the Treaty of Coruscant ( because being much closer, the latter taking place 3653 years before the battle of Yavin).
