- "There are days, and there are days."
- ―Teroj Kee
A standard day was a unit of time. Like other "standard" time units, it was based on the cycles of the planet Coruscant, which served as the galactic capital. As such, a standard day was divided into 24 standard hours, and 365 standard days made up a standard year.
Within a day, a specific point in time could be expressed in terms of hours and minutes. In written form, there was no separator between the hours and minutes (e.g. 1630 meaning 16 hours and 30 minutes).
