90,000 BBY, or 90,000 Before the Battle of Yavin, was a year of the Galactic Standard Calendar that fell within the Pre-Republic era. It was said that the Galactic City on the planet Coruscant stood as a many tiered settlement as early as 90,000 BBY. Thousands of years later, by the time of the Clone Wars, the planet-spanning settlement had grown to 5,127 levels stretching kilometers from the surface.
Behind the scenes
The 1994 novel The Courtship of Princess Leia by Dave Wolverton was the first source to establish that several of the levels of the Galactic City were more than ninety thousand years old by the time of the novel's events, which are set in 8 ABY. The 2009 reference book The Essential Atlas, authored by Daniel Wallace and Jason Fry, subsequently explicitly introduced the year 90,000 BBY in the context of the history of Coruscant's planet-wide city.

- The New Essential Chronology establishes that the Pre-Republic era preceded the foundation of the Galactic Republic, which Star Wars: The Old Republic Encyclopedia dates to 25,053 BBY.
- 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. dates the
- 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 , 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.
- 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.
- 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.
