Find your Moon sign from your birth date, time and city — the zodiac sign the Moon was in when you were born. Moon Sign Calculator is part of WebToolNest's collection of free everyday utilities. It works instantly in your browser with no account and no installation.
What is a Moon sign?
Your Moon sign is the zodiac sign the Moon was in when you were born. While your Sun sign describes your identity, the Moon describes your emotional world — your moods, comfort needs and how you care for others. Many people relate to their Moon sign more than to their Sun sign.
Do I need my birth time?
Usually not. The Moon spends about two and a half days in each sign, so on most dates the whole day falls in one sign and the calculator gives a definite answer. If the Moon changed sign on your birthday, the tool warns you and shows both signs — then your birth time decides which one is yours.
Results use the tropical (Western) zodiac and the Moon's exact position from an astronomy library, adjusted for your birthplace's time zone on that date.
