Standard year

"For almost three standard years, this war has raged. We can barely even count the numbers of the fallen."

- Jedi Master Plo Koon laments the Clone Wars

A standard year, also known simply as a year or a cycle, was a measurement of time.

On Coruscant, a year was made up of twelve months spanning 365 days of 24 hours each, with no leap years. The galaxy used a standardized dating system based off of the galactic capital Coruscant. By the time of the New Republic, the Galactic calendar would use the Battle of Yavin as the epicenter on which to date years.

On certain planets, including Lothal, a year was divided into four seasons (spring, summer, autumn, and winter) characterized by specific meteorological or climatic conditions. The planet Lothal based its yearly calendar on a system known as Lothal Years. A being's age was usually expressed in years. The passage of a thousand years was referred to as a millennium.

Behind the scenes
In Pablo Hidalgo's internal chronology, standard months are named "January" through "December," and standard years counted so that the Battle of Yavin is dated "May 1977."
