- "If these new droids do work out, I want to transmit my application to the Academy this year."
"You mean the next semester before the harvest?"
"Sure, there's more than enough droids."
"Harvest is when I need you the most. Only one more season. This year we'll make enough on the harvest so I'll be able to hire more hands. And then you can go to the Academy next year. You must understand I need you here, Luke."
"But it's a whole 'nother year."
- ―Luke Skywalker and Owen Lars
A standard year, also known more simply as a year or formally as Galactic Standard Year, was a measurement of time on the Galactic Standard Calendar, consisting of 368 standard days, with twelve months of at least 30 days each. 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 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.
Behind the scenes
Star Wars: The Roleplaying Game originally established a year that contained ten standard months (of seven standard weeks consisting of five days) plus three Fete Weeks and three more holidays, though this was overridden in favor of a 12-month dating system in later sources.
