Moon sign calculator: your sun, moon and rising

Your moon sign is the zodiac sign the Moon was in at the moment you were born. Enter your birth date, time and place in the calculator above and it will show it, along with your sun and rising signs.

The Moon moves through a whole sign in about two and a half days, so on some birthdays it changes sign partway through the day. The rising sign changes roughly every two hours, so it needs an exact time and place.

In Western astrology the sun sign describes your core identity, the moon sign your emotional needs, and the rising sign (ascendant) how you meet the world and how others first see you. Together they are often called your big three.

Positions are computed with the astronomy-engine library, which models the Sun and Moon to within a small fraction of a degree. Results use the tropical zodiac used in Western astrology. Vedic astrology uses the sidereal zodiac, so its signs usually differ.

Tick 'I don't know my birth time' and you will still get your sun sign, and your moon sign unless the Moon changed sign that day. A birth certificate or hospital record often lists the time.
