Notes and references[]

  1. Secrets of the Sisar Run, p. 22
  2. SWAJsmall.jpg "Galaxywide NewsNets" – Star Wars Adventure Journal 7
  3. The Essential Guide to Warfare and The New Essential Chronology establish the endpoints of this era as 19 BBY and 4 ABY.
  4. SWTOR mini.png Galactic History on The Old Republic's official website (article) (backup link) dates the Tho Yor Arrival, as described in Star Wars: Dawn of the Jedi 0, to the year BTC 32,800 of the calendar based on the date of the signing of the Treaty of Coruscant. Since the difference between that calendar and the Galactic Standard Calendar—based on the date of the Battle of Yavin—was 3,653 years per the reasoning here, the Tho Yor Arrival must have taken place in the year 36,453 BBY of the latter dating system. Therefore, the difference between the Galactic Standard Calendar and the dating system based on the Tho Yor Arrival that is featured in Dawn of the Jedi: Into the Void must be 36,453 years.
  5. Star Wars: The Old Republic Encyclopedia places the Treaty of Coruscant, which served as the zero point of a calendar adopted by the Galactic Senate following the conclusion of the Great Galactic War per SWTOR mini.png Galactic History on The Old Republic's official website (article) (backup link), in the year 3653 BBY of the Galactic Standard Calendar, which was based around the date of the Battle of Yavin. Thus, the difference between the two dating systems is 3,653 years.
  6. The New Essential Chronology establishes that the zero point of the calendar introduced by Tarsus Valorum was the Ruusan Reformation. The book places that event in the year of 1000 BBY of the Galactic Standard Calendar—which was based around the date of the Battle of Yavin—therefore establishing a difference of one thousand years between the two dating systems.
  7. The Essential Atlas places the Battle of Yavin, the zero point in the Galactic Standard Calendar per The New Essential Chronology, in 35:3 under the Great ReSynchronization dating system. The Essential Atlas also places the Battle of Selaggis on 43:2:28 and the Battle of Dathomir on 43:3:21. The Essential Guide to Warfare and The Essential Atlas both place the Battle of Dathomir in the year 8 ABY of the Galactic Standard Calendar. The Essential Guide to Warfare also places the Battle of Selaggis in 7 ABY, confirming the placement of the division between each Galactic Standard Calendar year as the third month in the Great ReSynchronization year. Thus, there is a two-month gap between the two dating systems, with the first two months of a GrS year being the last two of the preceding Galactic Standard Calendar year, and there is a total difference of 35 years and 2 months between the two systems.

  15. 15.0 15.1 SWAJsmall.jpg "Galaxywide NewsNets" – Star Wars Adventure Journal 3 dates the dissolution of the Imperial Senate to 35:3:5, which is the same day as the deaths of Owen and Beru Lars, according to Star Wars: Episode IV A New Hope. The Life and Legend of Obi-Wan Kenobi establishes that Luke Skywalker and Obi-Wan Kenobi spend the night in the Tatooine city of Bestine following the Lars murders, before embarking upon the rescue of Princess Leia the next day, during which the destruction of Alderaan also occurs, according to the Star Wars radio drama. Therefore, Leia Organa's rescue and the destruction of Alderaan take place on 35:3:6.
  16. Based on combined information from multiple sources, the events of Star Wars: Episode IV A New Hope can be determined to span five days: Given that The Essential Atlas establishes that the events of A New Hope begin on 35:3:3, the Battle of Yavin therefore takes place on 35:3:7.
