In astrology, the Moon sign and Sun sign are two key elements of a person’s natal chart. Here’s what they mean and how they differ:
What is a Moon Sign?
- The Moon sign represents the zodiac sign the Moon was in at the exact time of your birth.
- It reflects your emotional nature, subconscious mind, and inner self—the part of you that others may not easily see.
- It governs your:
- Feelings and instincts.
- Emotional reactions.
- Comforts and needs.
To calculate your Moon sign, the date, time, and location of your birth are needed because the Moon changes signs approximately every 2.5 days.
What is a Sun Sign?
- The Sun sign is the zodiac sign the Sun was in at the time of your birth.
- It represents your core personality, ego, and life purpose—the traits you consciously project to the world.
- The Sun sign is the most commonly known sign and is determined solely by your date of birth (e.g., Aries, Taurus, Gemini).
Key Differences
| Aspect | Moon Sign | Sun Sign |
| Symbolizes | Inner emotions, subconscious self | Core identity, outward personality |
| Visibility | Often hidden or subtle | Easily seen and expressed |
| Frequency of Change | Changes every 2.5 days | Changes approximately every 30 days |
| Influence | Emotional responses, instincts | Goals, ambitions, and overall character |
| Calculation | Requires birth date, time, and location | Requires birth date only |
An Example:
If your Sun sign is Leo, you might have a bold and confident outward personality. But if your Moon sign is Pisces, you may have a sensitive and intuitive inner world that isn’t immediately obvious to others.
Together, the Moon and Sun signs (along with the Rising/Ascendant sign) provide a more complete picture of your astrological personality.
