Standard day

A day was a unit of time on the Galactic Standard Calendar. One day was the amount of time it took for a planet to make one complete rotation on its polar axis. Twenty-four standardized hours was considered to be a standard day.

The length of a day varied between planets. The length of day for most terrestrial planets not subjected to tidal locking was in the range of 18 to 36 standard hours. Tide-locked planets did not have days. Satellite planets - moons orbiting a gas giant - were almost always tide-locked to the gas giant they orbited. Satellites may have days several dozen hours long (as long as it takes the satellite to orbit the gas giant).

During Roan Novachez's time at the Jedi academy on Coruscant, the days of the week were organized as Monoday, Duoday, Triday, Quadday, Pentaday, Hexaday and Heptaday.
