Moon Sign Calculator
Your Sun is who you’re becoming. Your Moon is what you need along the way. Find yours.
What your Moon sign tells you
In astrology, the Moon rules the inner weather: moods, instincts, memory, the body’s rhythms, and the private self you are at home with the door closed. Your Moon sign describes what makes you feel safe, what you reach for when you’re tired or hurt, and the kind of care that actually lands with you.
It’s often the placement people recognize themselves in most, because it’s the part of you that doesn’t perform. Two people with the same Sun sign can feel completely different to be close to, and the Moon is usually why.
Why your birth time can matter
The Moon is the fastest body in the sky. It crosses a whole sign in two to three days, so on most birthdays your Moon sign is the same from midnight to midnight. On the days it changes signs, the hour matters. If you don’t know your time, the calculator will tell you when that’s the case and show you both signs. Reading both guides is often the quickest way to know which one is yours.

Questions
What is my Moon sign?
Your Moon sign is the zodiac sign the Moon was in at the moment you were born. In astrology it describes your emotional life: what you need to feel safe, how you react when something hurts, and what comforts you.
Do I need my birth time to find my Moon sign?
Usually not, but sometimes it decides it. The Moon changes sign every two to three days, so on most birthdays it stays in one sign all day. If it changed signs on your birthday, this calculator tells you both possibilities, and your birth time settles it.
Why is my Moon sign different from my Sun sign?
The Sun spends about a month in each sign and the Moon only two or three days, so the two rarely match. Your Sun is what you’re building. Your Moon is what you need to keep going.
Is this Moon sign calculator accurate?
Yes. It uses astronomy-engine, a precise astronomical library, to find the Moon’s position for your birth moment in the tropical zodiac that Western astrology uses. With a birth time and city, the answer is exact to the degree.
Is my birth information saved?
No. The calculation happens in your browser. Your date, time and city are never sent to Feya or stored anywhere.
