Void-of-Course Moon

A “void-of-course” Moon is the stretch of time after the Moon has made its last major aspect to another planet in its current sign and before it moves into the next zodiac sign. It is a technical definition that follows from the Moon’s motion, not a prediction.

How it is defined

The Moon travels through all twelve signs in roughly 27–28 days, spending a little over two days in each sign. A void-of-course period begins at the Moon’s last exact major aspect within a sign and ends when the Moon enters the next sign (its ingress).

Editor’s note: a detailed, human-written explanation of how different traditions interpret the void-of-course Moon is coming soon. Please do not auto-generate astrological claims here.
