What is a Moon sign?

Your Moon sign marks where the Moon stood in the zodiac at the moment of your birth. In astrology it is read as a picture of your emotional needs, instincts and habits. For the longer explanation, see What your moon sign means.

Moon sign vs Sun sign

Your Sun sign is the one you give when someone asks "what are you?" It comes from your birth date alone and is read as your core identity and drive. Your Moon sign is read as what happens underneath: how you react, and what helps you feel settled.

The Sun stays in a sign for about a month. The Moon stays for about two and a half days. That is why two people with the same birthday can have different Moon signs, and why the calculator asks for the year and the time as well as the day.

Do I need my birth time?

It helps, but you can calculate without it.

The Moon spends about 2.5 days in each sign. On many dates it stays in one sign for the whole day, and the exact time makes no difference. It matters only on a date when the Moon crosses from one sign into the next.

If you do not know your birth time, tick "I don't know my birth time". The result uses a noon reference and is marked as unknown-time, hiding the Rising sign (Ascendant), Midheaven (MC), houses, exact degrees, and aspects. Because the calculator checks your entire local birth date for sign changes, if the Moon—or the Sun or another planet—changes sign on that day, it shows each possible sign rather than presenting a single noon sign as certain. A birth certificate or a family record is the best place to look for the time.

FAQ

How do you determine your Moon sign?

You need the position of the Moon at the moment you were born. The date and time give the moment, and the city tells the calculator which time zone to use. The calculator does the rest and shows the sign.

How long does the Moon stay in each sign?

About 2.5 days. A full trip around the zodiac takes roughly 27 days.

Will my Moon sign change over time?

No. The Moon moves every day, but your Moon sign is the one it held at your birth, and it stays the same for life.

Is this my Vedic Moon sign?

Not necessarily. This calculator uses the tropical zodiac. Vedic astrology, where the Moon sign is called rashi, uses the sidereal zodiac, and the sign it gives can differ from the one you get here.
