How to find your moon sign
A free AI astrology tool
When you say "I'm a [sign]," most people are referring to their sun sign. But astrology has another important sign called the "moon sign," which represents your emotions, inner self, and instinctive reactions. This article explains what the moon sign means, how it differs from the sun sign, and how to find it for free.
What is a moon sign?
A moon sign shows which sign the Moon was in at the moment you were born. The Sun takes about one month to move through a single sign, but the Moon moves to the next sign in about 2.5 days. Because of this, even people with the same birthday can have different moon signs if their birth times differ.

Frequently asked questions
Q. Can I find my moon sign even if I don't know my birth time?
Since the Moon moves through a sign in about 2.5 days, you can find your approximate moon sign from the date alone. However, if the Moon is near the boundary between signs, an accurate determination isn't possible without your birth time. When the birth time is unknown, aiAstro displays a result calculated at noon (12:00).
Q. What does it mean if my sun sign and moon sign are the same?
When your sun sign and moon sign are the same (common for people born around a new moon), that sign's traits appear very strongly. Your outer and inner selves align closely, and you tend to understand your own emotions easily.
Q. How accurate is the moon sign?
aiAstro uses an astronomical calculation engine to compute the Moon's position in real time. If your birth time is accurate, the moon sign determination is highly precise.
