How a void-of-course Moon is calculated

The Moon is void after it completes its final major aspect in a sign and before it enters the next sign. The calendar finds those exact contacts and sign ingresses, then shows the interval between them in your time zone.

The method

Method: Lilly — within-sign conjunction, sextile, square, trine and opposition to the seven traditional planets. Uranus, Neptune, Pluto and the nodes do not end a void period. Taurus, Cancer, Sagittarius and Pisces are marked with Lilly's traditional mitigation.

What the period means

In horary and electional practice, a void Moon suggests that the situation may not develop further in the expected way. It is a condition to weigh, not a stand-alone verdict, and whether stillness helps or hinders depends on what you are trying to do.

What this calendar does and does not tell you

Common questions

What does void of course mean?

It means the Moon will complete no more major traditional aspect before leaving its current zodiac sign.

Do I need my birth chart?

No. These are sky-wide lunar periods, not natal-chart calculations.

Does my location change the void Moon?

No. The underlying moments are the same worldwide. Your time zone only changes the clock time and date shown.

Why are some signs marked as softened?

Lilly says a void Moon can still perform somewhat in Taurus, Cancer, Sagittarius and Pisces. The calendar keeps the same void interval and marks that traditional qualification separately.
