Your moon sign is the zodiac sign the Moon was passing through when you were born. Where your sun sign is your core identity, your moon sign is your inner, emotional self — how you feel, comfort yourself, and love in private.

Do I need my birth time to find my moon sign?

Usually not. The Moon spends about two and a half days in each sign, so your birthday alone gives the right answer on most days. Only if you were born within a day of the Moon changing signs does the exact time settle it — add your birth time on your Big Three for certainty.

What is the difference between a moon sign and a sun sign?

Your sun sign (the famous one) is your core self and will; your moon sign is your emotional nature — the private you that comes out with the people closest to you. Most people feel their moon sign is the more accurate portrait of their inner life.

What your moon sign says about you

If the sun sign is the role you play in the daylight, the moon sign is who you are once the door closes. It governs your emotional weather — what soothes you, what you reach for when you're tired or hurt, how you show love to the handful of people you trust most. Two people can share a sun sign and feel like different species, and the moon is usually why.

Because the Moon moves quickly — roughly one sign every two and a half days — your moon sign is genuinely yours in a way a sun sign shared by a twelfth of the world isn't. It's the placement people tend to recognise the instant they read it.
