Moon Sign Calculator
Know your time. Live it well.
Your moon sign reveals your emotional nature, instincts, and subconscious self — things your sun sign cannot show. The Moon changes signs every 2.5 days, making it far more personally specific than your sun sign. Your nakshatra (Vedic lunar mansion) refines this further to one of 27 precise cosmic positions.

Frequently Asked Questions
What is a moon sign?
Your moon sign is the zodiac sign the Moon was in at the exact moment you were born. While your sun sign (determined by your birth date) represents your conscious identity, your moon sign represents your emotional nature, instincts, and subconscious self. It is often considered more important than the sun sign for understanding personality and emotional needs.
How is my moon sign different from my sun sign?
Your sun sign changes roughly every 30 days (as the Sun moves through the zodiac). Your moon sign changes approximately every 2.5 days (as the Moon moves much faster). Your sun sign represents your conscious self and outer personality; your moon sign represents your emotional world, instincts, and how you feel inside.
What is a nakshatra?
A nakshatra is one of 27 lunar mansions used in Vedic (Indian) astrology. The Moon completes its cycle through all 27 nakshatras in approximately 27.3 days. Each nakshatra has its own ruling deity, quality, and meaning. Knowing your birth nakshatra gives much greater precision than your moon sign alone — it is considered fundamental in Jyotish (Vedic astrology) for reading personality, timing, and compatibility.
Is the moon sign calculator accurate?
This calculator uses a simplified approximation based on the Moon's average orbital period of 27.3 days. For precise astrological use (especially for Vedic calculations and marriage matching), you should calculate using your exact birth time and location, as the Moon can shift signs in the middle of a day.
