What is a moon sign?
While your sun sign reflects your core identity, your moon sign describes your emotional nature — your instincts, what makes you feel safe, and how you process feelings beneath the surface. It's one third of your astrological "Big Three" (Sun, Moon and Rising).
The Moon moves quickly — changing signs roughly every two and a half days — so two people born on the same date can easily have different moon signs. That's why you need your birth date, and ideally your birth time, to find it accurately rather than guessing from your sun sign.

Frequently asked questions
How do I find my moon sign?
Enter your date of birth, time of birth and birth city into the calculator above. We compute the Moon's exact position from astronomical ephemeris data and return your moon sign instantly — free and with nothing stored.
Do I need my exact birth time for my moon sign?
Usually no. The Moon changes signs every ~2.5 days, so for most birth times your moon sign is unambiguous. If you were born on a day the Moon changed signs, an exact time confirms which one — so it's worth entering if you know it.
What's the difference between my sun sign and moon sign?
Your sun sign is your core identity and ego; your moon sign is your emotional inner world — how you feel and what makes you feel secure. Many people relate more to their moon sign privately than their public sun sign.
Can two people born on the same day have different moon signs?
Yes. Because the Moon moves so quickly, people born hours apart on the same date can have different moon signs, which is part of why charts are so individual.
