What is Moon Sign Calculator?
Your Moon sign represents your inner emotional world, instincts, and unconscious needs. While your Sun sign is how you appear to the world, your Moon sign is who you are in private.
This calculator uses the Julian Day Number astronomical formula to determine your Moon position at birth. The Moon moves approximately 13.17° per day through the zodiac, completing a full cycle every 27.3 days.
Note that the calculation has ±1 sign accuracy near cusp days. For precise results, consult a professional astrologer with your exact birth time.
