Moon Sign Calculator
Enter your birth date, time and place to find your Moon sign — the zodiac sign the Moon was in when you were born.
About Moon Signs
Your Moon sign shows your emotional nature, inner needs, and how you respond instinctively. The Moon moves fast — roughly one sign every 2.5 days — so exact birth time and location matter.
How this tool works
- We compute the Moon’s ecliptic longitude for your birth moment, then map that longitude to one of the twelve zodiac signs.
- Because accurate positions require astronomical calculations, this page can use an external astronomy API (see note).

What Is a Moon Sign?
Your Moon Sign represents the position of the Moon at the exact moment of your birth. Unlike your Sun Sign, which shows your outward personality, your Moon Sign reveals your emotional world, inner feelings, and how you naturally react to life’s situations. It helps you understand what truly makes you feel comfortable, secure, and emotionally fulfilled.
Why Knowing Your Moon Sign Matters
The Moon Sign plays a key role in astrology because it governs your intuition, emotions, and relationships. By discovering your Moon Sign, you gain deeper insights into your emotional needs and how you connect with others. It can explain why you might react differently from people who share your same Sun Sign.
For example, two people with the same Sun Sign can behave very differently if their Moon Signs are not the same. The Moon Sign adds a personal layer that defines your emotional patterns and inner desires.
How the Moon Sign Calculator Works
Our Moon Sign Calculator uses your date, time, and place of birth to find the exact zodiac sign the Moon was in when you were born. The Moon changes signs roughly every 2.5 days, so even a few hours can make a big difference — that’s why entering accurate details is important.
Once you input your birth data, the calculator instantly determines your Moon Sign and provides insights into your emotional personality.
Benefits of Knowing Your Moon Sign
- Understand your emotional strengths and weaknesses
- Improve your relationships by knowing your emotional needs
- Make better life and career decisions based on emotional alignment
- Deepen your self-awareness and inner balance
Conclusion
The Moon Sign Calculator is a simple yet powerful tool that helps you understand the emotional side of your personality. Whether you’re exploring astrology for fun or personal growth, learning about your Moon Sign can bring clarity, healing, and emotional peace.
