Example reading
Input: Born 22 July 1990, 15:15, Los Angeles, USA
Result: Moon in Leo (about 10 degrees). With a Cancer Sun, this person is likely to feel things deeply and privately yet need to be appreciated for the care they give. Leo Moon needs warmth, play and visible affection to feel secure. Under stress it can turn dramatic or proud, so it helps to ask directly for the recognition you want instead of waiting to be noticed.
What your moon sign means
In astrology the Sun is who you are becoming and the Moon is how you feel along the way. Your moon sign describes your instinctive reactions, comfort habits, what you need in close relationships and how you soothe yourself when things get hard.
It is often the sign people recognize the most strongly once they look it up, because it shapes the private side of personality that friends see only when you are relaxed. Two people with the same Sun sign but different Moons often handle stress in very different ways.
Use it as a prompt for self-knowledge. Ask yourself what makes you feel at home, what you do when you are overwhelmed, and what you wish people understood without being told.

How the moon sign is calculated
The Moon is the fastest-moving body in a chart. It circles the zodiac in about 27 days, spending roughly two and a half days in each sign and moving around 13 degrees every 24 hours. That speed is why moon signs are less obvious than Sun signs.
TarotDew calculates the Moon's true position with the open-source astronomy-engine library, accurate to well under one degree, and converts your birth time using the historical time zone and daylight saving rules for your birthplace.
- Enter your birth date.
- Add your birth time and city if you know them, so the exact moment is used.
- Read your Moon sign and house, then check the table above for the quick summary.
When birth time changes your moon sign
Because the Moon changes sign every couple of days, on roughly four days out of ten it switches signs at some point during the 24 hours. If you were born on one of those days, the Moon sign can be one of two signs depending on the clock time.
Time zones add another wrinkle. A birth at 11 p.m. in New York is already the next day in London, and the Moon calculation follows the universal time moment, not the local date on the certificate. That is why a city and time give a safer answer than a date alone.
If your result lands within a few degrees of a sign boundary and you are unsure of your birth time, read both neighboring signs and see which one feels more like you. Your Sun sign never has this problem for most birthdays, which is why the Moon rewards a little extra effort.
What to do with your moon sign
- Build routines around its needs, such as quiet mornings for Pisces or movement for Aries.
- Share it with a partner or close friend so they understand how you recharge.
- Compare it with your Sun and Rising sign in a full birth chart to see how the three work together.
- Check your daily horoscope and daily tarot card, which TarotDew can personalize with your Sun and Moon sign when you enter a birthday.

Frequently asked questions
What is a moon sign?
A moon sign is the zodiac sign the Moon occupied at your birth. In astrology it represents your emotional nature, instincts, comfort needs and private habits. It is often described as your inner self, in contrast to the Sun sign, which reflects your core identity and outward goals.
Do I need my birth time to find my moon sign?
Your birth date is enough on most days, but the Moon changes sign every two to three days. If you were born on a day it switched signs, the exact time decides the answer. Adding your birth time and city gives the most accurate result.
How often does the Moon change signs?
The Moon spends about two and a half days in each sign and completes the full zodiac in roughly 27 days. That is faster than any other body in your chart, which is why your moon sign can differ from the sign of friends born the same week.
Is my moon sign more important than my sun sign?
Neither one outranks the other. The Sun describes identity and direction, while the Moon describes feelings and needs. Many people find their Moon sign describes them better in private and in close relationships, so it is worth reading both side by side.
Why does my moon sign not sound like me?
A sign description is a general pattern, and your Moon also interacts with planets and houses in your chart. A tight aspect, or a birth near a sign boundary, can change the picture. Check a full birth chart and try the neighboring sign if your birth time is uncertain.
Is the TarotDew moon sign calculator free?
Yes. It is free, unlimited and needs no account or sign-up, and the page has no ads. If you add a birthday on the daily tarot page, TarotDew can also mention your Sun and Moon sign in your daily message.
