Moon sign calculator
Your moon sign is the zodiac sign the Moon was in at the moment of your birth. If the Sun is your identity, the Moon is your inner world: how you feel, what comforts you, what you need to feel safe. The Moon changes sign every two and a half days, so the time helps. Calculate yours for free.
What your moon sign reveals
The Moon rules emotion, memory, habit and the instinct to care. Your moon sign describes your private emotional landscape —the one that surfaces in intimacy and reaches back to childhood—, often very different from the face your Sun sign shows.
Why the time matters
The Moon is the fastest body in the chart: it crosses a sign in just two and a half days. If you were born on a day it changed sign, only the exact time decides which one. With your time we fix it without ambiguity.
Sun, Moon and one more
Your moon sign is one of the three pieces that define your character, along with the Sun and the rising sign. Calculate your chart and you'll have all three, plus every planet, house and aspect.
Frequently asked questions
- What is the moon sign?
- It's the zodiac sign the Moon was in when you were born. It reflects your emotional world, your needs and how you seek comfort.
- Do I need the time to know my moon sign?
- Not always, but it helps: the Moon changes sign every two and a half days. If you were born on a changeover day, only the exact time settles it.
- How is it different from the Sun sign?
- The Sun sign is your conscious identity; the moon sign, your inner emotional life. Many people recognise themselves more in their Moon than their Sun.
- Can I calculate it for free?
- Yes. The calculation is free and runs in your browser with real ephemerides; we don't store your date or time.
- Why do other sites sometimes give a different moon sign?
- Usually because of the time or the time zone. We use the exact time and place, with the correct zone, to avoid that error.
