Moon Sign Calculator

Enter your birth date and, if you know it, your birth time to find your Moon sign: the sign the Moon was travelling through when you were born. It is computed from real astronomy in your browser.

The Moon moves about 13 degrees a day, roughly half a sign, so an accurate birth time matters. Without one we use noon, and if the Moon changed signs that day your result could be the neighbouring sign.

How this works. Your Moon sign is calculated from real astronomy (the same engine used inside the Alya app), using the tropical zodiac. Your details stay in your browser and are only used to compute the position of the Moon. No birth place is needed here: the Moon's sign barely shifts with location, so this tool uses a neutral reference point and the effect on your result is tiny.

For entertainment and reflection. Astrology is a symbolic tradition, not a science. This result is grounded in the real position of the Moon, but its meaning is interpretive and is not medical, psychological, legal or financial advice.
