A local day or local rotation was a period of time. As a unit, local days were larger than divisions and fragments. The galactic standard units of time measurement, such as the standard hour, the standard day, and the standard year, were based on the local time periods of the galactic capital, the planet Coruscant. A Coruscant day was made up of 24 hours, and a Coruscant years was made up of 365 days.
One year on the planet Hoth was 549 local days, with one day consisting of 23 standard hours; one Hoth year corresponded to 526 standard days.

The planet Jakku had a year with 315 local days, where one local day was 26.8 standard hours; one Jakku year was 352 standard days long.
While one year on the planet Cato Neimoidia consisted of 278 local days, with one day consisting of 25 standard hours, one year on the planet Dantooine consisted of 378 local days, with one day consisting of 25 standard hours. The planets Neimoidia and Malastare both had local years that consisted of 221 local days, with each day making up 29 standard hours. A year on the planet Onderon was made up of 405 local days, with one day consisting of 28 standard hours. One Rodia year had 305 local days, with each day being made up of 29 standard hours.
Having driven back a Galactic Republic task force during the Clone Wars' Battle of Christophsis between the Republic and the Confederacy of Independent Systems, Confederacy tactical droid TI-99 reported his estimate that the natives' resistance on the planet Christophsis would collapse within the span of half a rotation to his superior, Admiral Trench. On the planet Vallt, one local day contained at least 18 divisions. On that planet, Assis was kept under a restraining bolt for more than 27 local days after being captured by Valltii soldiers.
