Moon sign calculator

Without an email subscription we store nothing on our server. Your browser remembers what you enter only in this tab, so you do not have to enter it again; it disappears when you close the tab.

How it works

The Moon spends about two and a half days in each sign, so on many days it changes sign. Without a birth time we show both possibilities and the exact moment of the change in your local time; with your birth time and place we give the exact sign and degree.

Dates are converted with the historical time zone of your birthplace, because the sign you get can depend on it.

The positions of the Sun, Moon and planets are calculated with astronomical precision for your moment and place of birth. The interpretation follows the Western astrological tradition: a centuries-old way of looking at the sky, not a scientific prediction.
