A void-of-course Moon is the gap after its last major aspect before it changes signs. It is a low-traction window best used for review, rest, and small tasks.

The Moon is void of course after it makes its final major aspect in a sign and before it enters the next sign. The period can be short or last many hours.
Astrologers treat this window as low momentum. It is fine for finishing, reflecting, and routine tasks, but it is not the best time to start something you want to grow fast.
The void window always happens inside a specific sign.
When the Moon's final conjunction, sextile, square, trine, or opposition completes, the void begins.
The void ends when the Moon enters the next sign.
If you want house context, use your birth time and location.
Use the window for cleanup, closure, and soft resets.
