Find your Moon sign
A birth time improves precision near the moments when the Moon changes signs, but you can still calculate without one.
Calculation accuracy
What you need for an accurate Moon sign
The Moon moves through the zodiac much faster than the Sun, changing signs roughly every two and a half days. Your birth date and place are usually enough to identify it, but an exact time removes ambiguity on a sign-change day.
This calculator sends your details to the same ephemeris used by the full app and does not save them. If you choose to continue, the details are held only in this browser tab so signup can prefill your chart.

Leo Moon
Warmth, recognition, and creative self-expression feed you. Being appreciated helps you open rather than perform.

Harmony and mutual understanding calm your system. You often discover what you feel through trusted relationships.
Scorpio Moon
You feel with intensity and protect what is vulnerable. Loyalty, privacy, and emotional truth matter more than ease.
Sagittarius Moon
Perspective and freedom restore you. Honest conversation, movement, and a larger horizon keep feelings from closing in.

Moon sign calculator FAQ
What is a Moon sign?
Your Moon sign is the zodiac sign occupied by the Moon at your birth. In astrology it is associated with emotional needs, instinctive reactions, habits, memory, and the conditions that help you feel secure.
Can I calculate my Moon sign without a birth time?
Usually, yes. If the Moon stayed in one sign throughout your birth date, a missing time does not change the result. On a day when the Moon crossed into another sign, an exact birth time is needed to choose between the two possibilities.
Is my Moon sign the same as my zodiac sign?
Not necessarily. The zodiac sign people commonly name is their Sun sign. Your Moon can be in any of the twelve signs, so it is often different from your Sun sign.
How is the Moon sign calculated?
The calculator converts your local birth details into an exact moment, resolves the location's time zone, and checks the Moon's astronomical longitude for that moment against the twelve zodiac sign ranges.
Does the calculator save my birth details?
No. The anonymous calculation is not written to the app database. Your details are placed in session storage only if you choose to continue with the chart, and that browser-tab storage disappears when the tab closes.
