Find Out Moon Sign: Moon Sign Calculator
In plain English Your moon sign is how you feel and what you need to feel safe.
To find out your moon sign, enter your birth date, birth time and birth city above. Your moon sign is the zodiac sign the Moon was in when you were born. It changes about every 2.5 days, so the date alone is enough unless the Moon switched signs on your birthday.
What your moon sign tells you
In plain Englishyour sun sign is how you show up, and your moon sign is how you feel underneath.
Astrologers use the Moon for mood, comfort and instinct. It describes what you reach for when you are tired, what a good night in looks like and what you need to hear after a bad day. The Sun, Moon and rising calculator puts it next to the other two parts of your Big Three.
How to find out your moon sign
In plain Englishyou need a date, and a time and place make it exact.
The Moon takes about 27 days to go around the zodiac, so it spends roughly two and a half days in each sign. To find your moon sign, the calculator turns your birth date and local time into the exact moment in UTC, reads the Moon’s position from an astronomy engine, and names the sign that position falls in. Most birthdays have one answer. About one birthday in five falls on a day the Moon changed signs, and then the time of birth decides.
Find moon sign by date of birth only
In plain Englishthe date is enough on most days, and the calculator tells you when it is not.
If you leave the time out, the calculator checks the whole day in your birth city. When the Moon stays in one sign, you get that sign. When it moves, you see both signs, with a short reading for each, so you can read both and keep the one that sounds like you. Adding a birth time from a birth certificate settles it.
The astrological moon sign in each of the twelve signs
In plain Englishthe sign changes how the Moon’s needs look from the outside.
A fire moon (Aries, Leo, Sagittarius) processes feelings by moving and talking. An earth moon (Taurus, Virgo, Capricorn) calms down through routine and physical comfort. An air moon (Gemini, Libra, Aquarius) steadies itself by putting feelings into words or into ideas. A water moon (Cancer, Scorpio, Pisces) feels everything first and explains it later. Open the Cancer page, or any other sign page, for the full description of that sign.
What to do with your moon sign
In plain Englishuse it as a note to yourself about what you need.
Astrologers split on how much a moon sign predicts, and there is no scientific evidence that it does. Treated as a prompt for self-reflection, it is useful: it asks what you need when you are stressed and whether the people close to you know that. If you are curious about someone else’s moon, the compatibility calculator and the synastry chart compare two charts, and what moon sign is today shows where the Moon is right now. For every planet and house, use the full birth chart calculator.
What each moon sign means
Questions people ask
- What is my moon sign?
- Your moon sign is the zodiac sign the Moon was in at the moment you were born. Enter your birth date, time and city in the calculator above and it names the sign, shows how far into it the Moon had moved and links to that sign's page.
- How to find out my moon sign?
- Use your birth date, your birth time if you have it, and your birth city. The city matters because the Moon crosses a sign boundary at one exact instant, and your local clock time decides which side of that line you were born on.
- Can I find my moon sign by date of birth only?
- Yes, most of the time. The Moon stays in one sign for about two and a half days, so the date alone gives one answer on roughly four days out of five. When the Moon changed sign on your birthday, the calculator shows both possibilities until you add a birth time.
- What is an astrological moon sign?
- An astrological moon sign is the Moon's position in the tropical zodiac at your birth. Astrologers read it as your emotional style: what calms you, what unsettles you and how you react before you think.
- What if I do not know my birth time?
- Tick the box that says you do not know your time. If the Moon stayed in one sign all day, you get one answer. If it changed sign that day, you see both signs and can use the descriptions to decide which fits you better.
- How is the moon sign different from the sun sign?
- The sun sign is the zodiac sign the Sun was in and changes about once a month. The moon sign is where the Moon was and changes about every two and a half days, so two people with the same birthday month often have different moon signs.
