How long is a day on Saturn?
Data as of July 2026
10 h 39 minone full spin
A day on Saturn lasts 10 h 39 min. That is 44% of an Earth day. Saturn has no solid surface, so its day is the time the planet takes to turn once.

Why Saturn's day is so short
Saturn has no surface to watch go round, so its day is timed from its magnetic field and, more recently, from ripples its interior raises in the rings. Estimates run from about 10 h 33 min to 10 h 39 min; this page uses NASA's figure of 10.66 hours.

Day length on every world
| World | Day (sunrise to sunrise) | One spin |
|---|---|---|
| Jupiter | 9 h 56 min | 9 h 56 min |
| Saturn | 10 h 39 min | 10 h 39 min |
| Neptune | 16 h 7 min | 16 h 7 min |
| Uranus | 17 h 14 min | 17 h 14 min (backwards) |
| Earth | 24 h 0 min | 23 h 56 min |
| Mars | 24 h 40 min | 24 h 37 min |
| Pluto | 6.4 Earth days | 6.4 Earth days (backwards) |
| Venus | 117 Earth days | 243 Earth days (backwards) |
| Mercury | 176 Earth days | 58.6 Earth days |
Earth's spin, against the stars, takes 23 h 56 min; the extra four minutes to a 24-hour day come from Earth moving along its orbit while it turns. On Saturn the same effect is too small to matter.
