Standard year

A standard year, also known more simply as a year or formally as Galactic Standard Year, was a standard measurement of time in the galaxy. The term year often referred to a single revolution of a planet around its star, the duration of which varied between planets; the standard year was specifically a Coruscant year, which was the galactic standard. The Coruscant solar cycle was 368 days long with a day consisting of 24 standard hours.

The length of a planetary year was determined by the orbital radius and speed of the planet. Satellite planets—moons orbiting a gas giant—were almost always tide-locked to the gas giant they orbited, and may have had days several dozen hours long (as long as it took the satellite to orbit the gas giant). The local year of a satellite depended on the orbit of the gas giant and may have been several standard years long.

A standard year had been originally defined as 10 standard months + 3 festival weeks + 3 holidays = 368 standard days, defining the Galactic Standard Calendar. However, calendar reforms had eventually changed the Galactic Standard Calendar to a 12-month/368-day calendar.
