The Moon rises about 50 minutes later each day

When does the Moon rise tomorrow?

The Moon rises about 50 minutes later each day, so tomorrow’s moonrise is about three-quarters of an hour after today’s.

Why it works

The Moon goes round the Earth in the same direction as the Earth turns, once in 27.3 days against the stars and 29.5 days against the Sun. Each day it has moved on about 13° and the Earth has to turn a little further to catch it up, which takes about 50 minutes. Full moon therefore rises at sunset, the last quarter near midnight, and a new moon at sunrise.
