What is my Moon sign?
The Moon moves fast. Give the date, and the time if you have it, and the calculator names the sign and degree.
How to read it
What the result means
Reading your result
The Moon sign is how you feel and what you need to feel safe: the reactions that happen before the thinking does. Where the Sun is who you are becoming, the Moon is who you already are at three in the morning. Most people who feel their Sun sign does not fit are reading their Moon.
The result names your Moon sign and its degree, and shows the whole chart around it. The Moon's house, if you gave a birth time, says where in your life those needs play out: a fourth-house Moon needs home, a tenth-house Moon needs to be seen doing good work.
If the Moon was within a few degrees of a sign boundary on your birthday and you gave no time, the calculator will say it cannot place it rather than guess. The Moon moves about half a degree an hour, so even an approximate time is enough to settle it.

Common questions
Moon sign calculator, answered
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 most birth dates fall clearly inside one. About one birthday in six lands on a sign change; for those, the calculator asks for a time rather than guessing.
What does my Moon sign mean?
Your emotional nature: how you react, what you need to feel safe, and what you reach for under stress. It is the sign most people recognize themselves in once they learn it, and the one that matters most in close relationships.
Can my Moon sign and Sun sign be the same?
Yes. You were born near a new Moon, when the Moon and Sun share a sign. It tends to make the sign's traits unusually consistent between what you want and what you need.
Why do Moon sign calculators disagree?
Almost always the time zone or a birth near a sign change with no time given. This calculator resolves the historical time zone from your birth place and refuses to guess at a boundary, so a result here is one you can rely on.
