Astrology Ephemeris Calculator:
| From: | To: |
In astrology, your sun sign represents your core identity and ego, determined by the position of the sun at your time of birth. Your moon sign reflects your emotional nature and inner self, determined by the moon's position at birth.
The calculator uses astronomical ephemeris data to determine the precise positions of the sun and moon at your exact time and place of birth, then maps these positions to the zodiac signs they occupied at that moment.
Details: Understanding both your sun and moon signs provides deeper insight into your personality, emotional needs, and how you express yourself in the world. While the sun sign shows your basic nature, the moon sign reveals your emotional responses and unconscious patterns.
Tips: For accurate results, enter your exact birth date, time (as precise as possible), and birthplace. The more accurate your information, the more precise your astrological calculations will be.
Q1: Why do I need both birth time and place?
A: Astrological calculations depend on your exact geographical location and time of birth to determine the precise positions of celestial bodies in relation to your birthplace.
Q2: What if I don't know my exact birth time?
A: While an exact time is ideal, you can use noon as a default, though this may affect the accuracy of your moon sign calculation more than your sun sign.
Q3: How often do moon signs change?
A: The moon changes signs approximately every 2-3 days, moving through all 12 zodiac signs in about 28 days.
Q4: Are there other important astrological placements?
A: Yes, a complete astrological chart includes many planetary positions and aspects, but sun and moon signs are among the most fundamental components.
Q5: Is this calculator suitable for serious astrological study?
A: While this calculator provides basic information, professional astrologers use specialized software for more comprehensive chart calculations and interpretations.
