Timeline of galactic history/Legends

The most used calendar in the galaxy, introduced during the time of the New Republic, is centered around the Battle of Yavin as the staring year. BBY stands for Before the Battle of Yavin, and ABY stands for After the Battle of Yavin. A galactic standard year, based on the length of a year on the Coruscant Standard Calendar, is 368 standard days, one standard day being a day of equal length as a day on Coruscant (twenty-four hours). As the existence of the hyperdrive allows space travellers to bypass the laws of the theory of relativity, a single duration of time passes at all locations equally over a given interval.

This dating system is used almost exclusively by the Rebel Alliance, the New Republic, and the Galactic Alliance. The earlier Galactic Empire preferred to date events from the Great Resynchronization of 35 BBY, or from the Emperor's ascension to the throne (19 BBY). The Galactic Republic dated years from the Ruusan Reformation of 1,000 BBY.

Time Measurement
In the The Galaxy:


 * 368 days = 1 year
 * 60 minutes = 1 hour
 * 24 hours = 1 day
 * 5 days = 1 week
 * 7 weeks = 1 month
 * 35 days = 1 month
 * 10 months + 3 festival weeks + 3 holiday days = 1 year

The Tapani Sector's Year

 * By the Tapani Sector's domestic calendar, which is Galactic Standard with local names, the year flows as follows:
 * Month 1: Elona
 * Month 2: Kelona
 * Holiday 1: Tapani Day
 * Month 3: Selona
 * Festival Week 1: Expansion Week
 * Month 4: Telona
 * Month 5: Nelona
 * Holiday 2: Productivity Day
 * Month 6: Helona
 * Festival Week 2: Shelova Week
 * Month 7: Melona
 * Month 8: Yelona
 * Holiday 3: Harvest Day
 * Month 9: Relona (The Freeworlds Region of the Tapani Sector also recognizes Relona 10 - 15 as Independence Week.)
 * Month 10: Welona
 * Festival Week 3: Winter Fete

The Galactic Year

 * From the above information, we can extrapolate that the year, whether Tapani-named or not, in the Star Wars galaxy flows as follows:
 * 2 months
 * 1 holiday
 * 1 month
 * 1 festival week
 * 2 months
 * 1 holiday
 * 1 month
 * 1 festival week
 * 2 months
 * 1 holiday
 * 2 months
 * 1 festival week

The week

 * The week flows as follows:
 * Day 1: Atunda
 * Day 2: Katunda
 * Day 3: Satunda
 * Day 4: Datunda
 * Day 5: Natunda
