Void-of-course: meaning in astrology
The Moon is void-of-course after it makes its last major aspect to another planet in a sign and before it enters the next sign. The void can last a few minutes or more than a day. Western electional astrology traditionally advises against starting important things during it, on the idea that they lose direction.
It is a Western technique; Vedic muhurta uses tithi, nakshatra and other factors instead.

How we calculate
Is astrology a guarantee of what will happen?
No. These calculations locate celestial bodies; astrology is a reflection and timing tradition, not evidence of guaranteed health, financial or relationship outcomes.
How are these results calculated?
Positions come from Astronomy Engine, an open-source astronomy library, and are checked against Swiss Ephemeris in our methodology tests. Western readings use the tropical zodiac; Vedic readings subtract the Lahiri ayanamsa. Terms are defined in the glossary.
