What does your birth moon phase mean?
Your sun sign comes from where the sun sat on your birthday, but the moon was somewhere too, moving through her twenty nine and a half day cycle. The phase she was in, new, full, waxing or waning, is read as a softer, more private layer of your nature: your instincts, your inner rhythm and the way you grow. It is a lovely companion to your sun and moon signs, and a beautiful thing to know about yourself.
The eight birth moon phases
- New moon. A natural beginner and quiet visionary.
- Waxing crescent. A hopeful builder of dreams.
- First quarter. A doer who grows through action.
- Waxing gibbous. A refiner who perfects and improves.
- Full moon. Radiant, expressive and deeply feeling.
- Waning gibbous. A giver and a natural teacher.
- Last quarter. A releaser who clears the way.
- Waning crescent. An old soul, wise and restful.

A gentle note
The moon's one clear effect on Earth is the ocean tides. The idea that your birth phase shapes your character is a gentle tradition rather than science, so wear it lightly and take what feels true. It is a pretty mirror and a lovely thing to share, not a rule for who you are.
Birth moon phase FAQ
What moon phase was I born under?
Enter your date of birth above and the tool works out the exact phase, names it, shows how much of the moon was lit, and what that phase is traditionally said to mean for your nature.
What does it mean to be born under a full moon?
Being born under a full moon is traditionally read as radiant, expressive and emotionally open. Full moon people are often magnetic and deeply feeling, born, the tradition says, to illuminate.
Is the birth moon phase the same as my moon sign?
No. Your moon sign is the zodiac sign the moon was in, while your birth moon phase is how lit the moon was, new through full. They are two different, complementary pieces of your chart.
How accurate is the birth moon phase?
The astronomy is precise, worked out from the moon's position on your date. The personality meaning attached to each phase is a tradition rather than a measurement, so enjoy it as reflection, not fact.
