Sun and Moon Sign Calculator
What is a Sun Sign?
Your Sun sign is the zodiac sign the Sun occupied at the time of your birth. It represents your:
- Core personality
- Ego and self-expression
- Life purpose and identity
For example, if you’re a Leo Sun, you naturally shine with confidence and creativity. If you’re a Capricorn Sun, you thrive on discipline and ambition.
What is a Moon Sign?
Your Moon sign is the zodiac sign where the Moon was during your birth. Unlike the Sun, which stays in one sign for about a month, the Moon changes signs every 2.5 days. That’s why your exact birth time can make a big difference in calculating it accurately.
Your Moon sign rules your:
- Emotional nature
- Instinctive reactions
- Inner needs and comfort zone
For example, a Cancer Moon feels emotions deeply and values family bonds, while a Gemini Moon processes feelings through communication and curiosity.

Sun-Moon Compatibility: Your Inner Dialogue
Your Sun and Moon signs don’t just stand alone—they interact with each other. This combination shows whether your inner world and outer expression are in harmony or tension.
- Fire Sun + Fire Moon → Passionate, bold, driven.
- Earth Sun + Water Moon → Grounded, nurturing, emotionally steady.
- Air Sun + Air Moon → Intellectual, curious, fast-moving.
- Fire Sun + Water Moon → Fiery outside but deeply sensitive within.
For example, a Sagittarius Sun + Cancer Moon person is adventurous on the outside but craves emotional security within.
Why Your Element Balance Matters
Your Sun and Moon both belong to one of the four classical elements:
- Fire (Aries, Leo, Sagittarius) → Passion, action, energy
- Earth (Taurus, Virgo, Capricorn) → Stability, practicality, structure
- Air (Gemini, Libra, Aquarius) → Ideas, communication, intellect
- Water (Cancer, Scorpio, Pisces) → Emotions, intuition, empathy
The calculator gives you a balance analysis, showing if you’re heavily weighted toward one element or balanced across all. This can explain why you act a certain way in relationships, work, or personal life.
