Moon sign calculator
Your Moon sign is the zodiac sign the Moon was travelling through on the day you were born. Enter your birth date, and your time and place if you know them, to find it.
What your Moon sign means
In astrology the Moon stands for your inner life: how you feel, what you need to feel safe, the habits you fall back on when you are tired. Your Sun sign is who you aim to be; your Moon sign is closer to how you respond when nobody is watching.
Two people with the same Sun sign can have very different Moons, which is one reason a Sun-sign horoscope can feel too general.
Why the birth time matters (sometimes)
The Moon changes sign about every two and a half days, faster than any other body in the chart. Most birth dates give a clear answer. If the Moon changed sign on your birthday, the hour you were born decides which sign is yours.
This calculator uses your birth time and place when you give them, and tells you honestly when the Moon was near a sign change and the answer is uncertain.
How to use it
Read your Moon sign next to your Sun and Rising signs. The three together describe core identity, emotional needs and outward manner. Treat it as a way to reflect on yourself rather than a fixed label.
Frequently asked questions
How do I find my Moon sign?
Enter your date of birth in the calculator. Adding your birth time and place makes the answer exact on days when the Moon changed sign.
Is the Moon sign more important than the Sun sign?
Neither is more important. The Sun is your core identity and the Moon your emotional nature. Astrologers read them together.
Can my Moon sign be the same as my Sun sign?
Yes. Born on a New Moon, the two sit in the same sign, which many astrologers read as a very focused personality.
Is this calculator accurate?
It computes the Moon's position for your birth instant from astronomical formulas, and reports when the result is too close to a sign boundary to be sure.
