Notes and references[]

  1. Secrets of the Sisar Run, p. 22
  2. The Essential Guide to Warfare and The New Essential Chronology establish the endpoints of this era as 19 BBY and 4 ABY.
  3. 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.
  4. 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.
  5. 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.
  6. 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.

  13. 13.0 13.1 13.2 The New Essential Guide to Characters places this event when Wedge Antilles was 17 years old.

  15. The Truce at Bakura Sourcebook places this event two years after the Dominant's commission, that occurred "almost a decade" before the Battle of Endor.
  16. In Chapter 18 of Children of the Jedi, Leia states that Irek "had to have been at least four years old" when Leia first encountered Roganda before the Battle of Yavin. This was referenced in The Emperor's Pawns, which states that Irek was eight years old at the Battle of Endor in 4 ABY. However, this reference was ignored by later sources, such as The Essential Guide to Characters and the Jedi Academy Training Manual which sets Irek's age at 14 in Children of the Jedi, which would place his birthdate as 2 BBY. For the purposes of this article, the original 4 BBY date is used.
