Moon sign calculator
Your Moon sign describes your emotional needs and instincts. It works from your birth date alone, and we’ll tell you if the time matters.
Why the Moon sign can change on your birthday
The Sun creeps about 1° a day and stays in a sign for a month. The Moon covers 12–15° a day, so it crosses a whole sign in about 2½ days. Pick a day in 2026 and scrub through its 24 hours.
Moon 14°14′ Gemini
Sun 11°05′ Capricorn. That day the Moon travelled 15.0° (the arc behind it) without leaving its sign, so everyone born that day shares the Moon sign.
Reading your Moon sign
The Moon is the fastest body in the chart and the one astrologers associate with the body’s rhythms, moods, memory and home. Your Moon sign is the answer to “what do I need to feel okay?”. It’s often the part of a chart people recognise most in themselves once they read it, because it describes reactions rather than ideals.
The Moon’s element is a quick first read: fire Moons (Aries, Leo, Sagittarius) need action and enthusiasm, earth Moons (Taurus, Virgo, Capricorn) need stability and tangible comfort, air Moons (Gemini, Libra, Aquarius) need to talk things through, and water Moons (Cancer, Scorpio, Pisces) need emotional closeness and time to feel.
Pair it with your Sun and Rising for the classic Big 3, or compare Moons with a partner on the synastry chart. Sun–Moon contacts between charts are one of the oldest compatibility markers.

Questions people ask
What is my moon sign?
It’s the zodiac sign the Moon was in when you were born. Enter your birth date, and ideally time and place, above. The calculator tells you whether the Moon changed sign that day.
Do I need my birth time for my moon sign?
Often not. The Moon spends about 2½ days in each sign, so on most dates it stays in one sign all day. On roughly one day in three it changes sign, and then your birth time decides it. The calculator tells you which case you are.
What does the moon sign mean?
In Western astrology the Moon describes your emotional nature: what makes you feel safe, how you react under stress, how you nurture and want to be nurtured, and your habits and instincts.
Is the moon sign the same as the moon phase?
No. The moon sign is the Moon’s position in the zodiac; the phase is the angle between the Sun and Moon (new, full, and so on). You can have a full Moon in any sign except the Sun’s own.
Which is more important, sun or moon sign?
Neither “wins”. The Sun is your conscious drive and identity; the Moon is the private, instinctive side, often more visible to people you live with than to acquaintances.
