okay, so

the battle of yavin was 1,000 years after the ruusan reformation. 22 BBY (before battle of yavin), the start of the clone wars, is 978 ARR (after ruusan reformation). 0 BBY is 7977 CRC (coruscant reckoning calendar)

in 968 ARR (32 BBY, 7945 CRC) the clones are commissioned by jedi master sifo-dyas, who’s later murdered by count dooku.

10 years later at the start of the clone wars (978 ARR, 22 BBY, 7955 CRC) obi-wan kenobi is elected to the jedi high council, anakin skywalker is knighted and assigned ahsoka tano as a padawan (at nineteen!!!!!!! he’s like barely five years older than her, genuinely wtaf). obi-wan is now a high general, putting him in charge of the third systems army, the seventh sky corps, and the 212th attack battalion more specifically. this is also likely when cody gets promoted to marshal commander.

the war ends for years later, 981 ARR 19 BBY 7958 CRC. order 66 is executed, anakin skywalker falls to the dark side and massacres the jedi temple of coruscant, padme amidala gives birth to twins fathered by anakin skywalker, leia is entrusted to bail organa while luke is sent to live with anakin’s step-brother on tatooine, obi-wan kenobi and the rest of the remaining jedi order go into hiding.

19 years later, 1000 ARR 0 BBY 7977 CRC, the original series happens, yippee.
