Star Wars Expanded Universe


The Star Wars expanded universe (formerly branded as the Star Wars Expanded Universe or SWEU) encompasses all authorized media and officially licensed Star Wars fictional material. The expanded universe includes books, comic books, video games, toys, television films and other assorted media. Any media directly produced by Lucasfilm is considered official Star Wars canon: the Star Wars films, the Clone Wars TV series and the Rebels series.

In April 2014, Lucasfilm announced that all previously released expanded universe content would be declared non-canon and rebranded as Star Wars Legends. A new company division, Lucasfilm Story Group, would ensure from then on that all forthcoming comics, books, games and other media were non-contradictory to the films, other canon media and each other. Given they are part of a similar story, however, content and characters based on Legends works may appear in the new "storytelling approach".

Unlike the films, which are set over a span of over 66 years, the "Legends" branded expanded universe takes place over 37,139 years in the Star Wars "Legends" universe. The earliest work involving the expanded universe chronologically is the Dawn of the Jedi comic series, whose earliest events take place 37,000 years before the films. The latest content on the timeline is the Legacy comic series, which is set at most 138 years after Return of the Jedi.

The Galactic Standard Calendar was the standard measurement of time in the Star Wars galaxy. It centered around the Coruscant tropical year. The Coruscant solar cycle was 368 days long; with a day consisting 360 NET degrees (or 24 standard UTC hours). Numerous epochs were used to determine calendar eras. The most recent of these calendar eras used the Battle of Yavin (i.e. the destruction of the first Death Star) as its epoch, or "year zero": BBY (Before the Battle of Yavin), and ABY (After the Battle of Yavin).
