What is a void-of-course Moon?

Updated September 25, 2026

A void-of-course Moon is the period between the Moon's last major aspect in a sign and its entry into the next sign. It happens every couple of days and can last minutes or more than a day. Traditional astrologers suggest avoiding starting important things during it; in practice, it's an optional cue to do routine or reflective work.

How it's defined

Once the Moon makes its last conjunction, sextile, square, trine or opposition to a planet before changing signs, it's "void" until the ingress.

How some people use it

Admin, filing and inbox cleanup
Reviewing plans rather than launching
Rest

Keep it in proportion

There's no evidence launches fail during a void Moon. Deadlines and readiness should drive timing.
