Free Moon Sign Calculator Online: Find Your Moon Sign Now
The Moon represents your inner emotional world, your instincts and deepest needs. Discover what the Moon's position at your birth reveals.
Complete Guide to the Moon Sign
The free Moon sign calculator on stars.expert finds the zodiac sign the Moon occupied at the moment of your birth and returns it together with the exact degree, phase and a short narrative interpretation. Your Moon sign describes the instinctive, emotional layer of your chart, what you feel before you think it, and in the tradition that runs from Dane Rudhyar to Stephen Arroyo it complements the Sun by revealing inner needs and habitual responses. The engine is the Swiss Ephemeris library maintained by Dieter Koch and Alois Treindl at Astrodienst, calibrated against NASA JPL DE441 with residuals under ±0.001 arcsecond compared with JPL Horizons. Because the Moon moves about 13 degrees per day and changes sign every two to three days, the date and place of birth are usually enough; the time of birth is helpful when you were born close to a sign change. The tool is free, requires no login or payment, and gives you the same observation-grade output that professional software such as Solar Fire or Morinus delivers, accessible to anyone curious about evidence-based astrology.
The Moon and Emotions
The Moon's position at birth reveals how you process emotions, what makes you feel safe, and how you care for others. It's your instinct, your automatic reaction to life events.
