What Is a Moon Sign?

Your Moon sign is the zodiac sign the Moon was passing through at the exact time of your birth. Because the Moon moves quickly - changing signs every 2.5 days - it has a powerful influence on your emotional nature.

Think of it this way:

• Sun Sign = Your identity, ego, and personality.
• Rising Sign = How others see you.
• Moon Sign = Your feelings, emotional needs, and instincts.

For example:

• A Leo Moon may crave affection, creativity, and admiration.
• A Scorpio Moon may feel things intensely and need deep emotional bonds.
• A Pisces Moon may be intuitive, dreamy, and highly empathetic.

This makes your Moon sign one of the most important keys to understanding your true self.

Why Is Your Moon Sign Important?

Your Moon sign shapes the way you:

• Process emotions – How you react to challenges or joy.
• Form relationships – What makes you feel secure and loved.
• Nurture yourself – Your comfort zone and inner world.
• Connect spiritually – The Moon governs intuition and cycles.

This is why two people with the same Sun sign can be so different. A Cancer Sun with a Sagittarius Moon might seem more adventurous than emotional, while a Cancer Sun with a Taurus Moon may appear nurturing and grounded.

How to Use the Moon Sign Calculator

Using the calculator is simple:

1. Enter your birth date.
2. Add your birth time (the closer to exact, the better).
3. Choose your birth location from the list.
4. Select your time zone.
5. Click Calculate Moon Sign.

Your personalized Moon sign results will appear instantly, complete with interpretations and lunar details.

A Note on Accuracy

Because the Moon changes signs every 2.5 days, your birth time matters a lot. Even a few hours’ difference can shift your Moon sign. That’s why our calculator is a great starting point—but if you want a fully precise chart, a professional astrologer can confirm the exact details.
