Moon Sign Calculator

Enter your birth date using the date picker, then provide your birth time as accurately as possible. The Moon moves quickly through the zodiac, spending only about two and a half days in each sign, so even a few hours can make the difference between one Moon sign and the next. Select the timezone of the location where you were born so the calculator can convert your local birth time to UTC.

Click Calculate Moon Sign and the tool will display your lunar sign along with detailed information about your emotional traits, core needs, instincts, and compatibility with other Moon signs. If you do not know your exact birth time, noon is a reasonable default, but keep in mind that the result may be less accurate if you were born near a sign boundary.

What Is Your Moon Sign?

In astrology, the Moon sign represents your emotional inner world, subconscious patterns, and instinctive reactions. While your Sun sign describes your conscious identity and outward personality, the Moon sign reveals how you process feelings, what makes you feel safe, and how you nurture yourself and others. It is often described as your "private self" -- the part of you that only close friends and family see.

Sun Sign vs Moon Sign vs Rising Sign

Your Sun sign is determined by your birth date and governs your core identity, ego, and life purpose. Your Moon sign is determined by the Moon's exact position at your moment of birth and governs emotions, habits, and comfort. Your Rising sign (Ascendant) is the zodiac sign that was on the eastern horizon at the time and place of your birth, shaping how others first perceive you and your outward demeanor. Together, these three placements form the foundation of a natal chart and offer a well-rounded portrait of personality.

How the Moon Affects Emotions

The Moon completes one orbit around the Earth roughly every 27.3 days, passing through all twelve zodiac signs in that cycle. Astrologers believe that the sign the Moon occupies at any given time colors the collective emotional atmosphere, and the sign it occupied at your birth permanently shapes your emotional baseline. People with fire-sign Moons (Aries, Leo, Sagittarius) tend to react with passion and enthusiasm. Earth-sign Moons (Taurus, Virgo, Capricorn) seek stability and practical comfort. Air-sign Moons (Gemini, Libra, Aquarius) process feelings through logic and communication. Water-sign Moons (Cancer, Scorpio, Pisces) experience emotions deeply and intuitively.
