A "rotation" in Star Wars refers to a planet's rotation on its axis, essentially meaning one local day on that planet. However, the exact length of a rotation can vary depending on the planet in question.
- The standard reference for a rotation is usually based on Coruscant, the Core World and former capital of the Republic and Empire, where one rotation equals 24 hours, similar to an Earth day. This is considered the Galactic Standard Time (GST)
- Other planets have different rotation lengths. For example, Tatooine has a rotation of about 23 hours and 30 minutes, slightly shorter than Coruscant's day
. Geonosis has a rotation of about 30 hours, and Mustafar's day lasts 36 hours
- When characters mention "rotations" without specifying a planet, it generally means the standard day based on Coruscant's rotation. But when referring to local time, a rotation means the local planet's day length, which can vary widely
In summary, a rotation is a full day on a planet, with the standard rotation being 24 hours on Coruscant, but it can differ significantly on other planets across the Star Wars galaxy
