How this calculator works
It computes where the Moon stood along the zodiac at the moment you were born, as seen from the Earth, and names the sign that position falls in. The position comes from open-source astronomy code that runs on this page. Our editorial policy explains how the site’s numbers are made.
Why a birth time can matter
The Moon crosses a whole sign in roughly two and a half days, so it often changes sign at some point during a day. If your birthday was one of those days, a date alone cannot say which side of the change you were born on. The calculator then shows both possible signs and asks for a birth time and time zone.
If you give a time without a time zone, the calculator cannot know which moment you mean, so it treats the result as uncertain whenever the answer could differ between places.
Choosing the time zone
Pick the zone of the place where you were born, not where you live now. The list is your browser’s own list of time zones and it knows each zone’s past daylight-saving rules. There is no city search, and nothing you choose is sent anywhere.
What the Moon sign is used for
In astrology the Moon stands for feeling and habit, where the Sun stands for the core of a person. That is the traditional reading; it is a way to reflect, not a test result, and this page does not give relationship advice.
