Free Moon Sign Calculator
Updated June 2026
Find your Moon sign — the zodiac sign the Moon was in at the moment of your birth.
Calculate your Moon sign — the zodiac sign the Moon occupied at the exact moment of your birth. The Moon moves through each sign approximately every 2.5 days, making it the fastest-moving body in the birth chart after the Sun.
What your Moon sign means
While your Sun sign reflects your conscious identity, your Moon sign reveals your emotional instincts, inner needs, and subconscious patterns. It shows how you respond instinctively to the world and what you need to feel emotionally secure.
Moon sign calculations use the tropical (Western) astrology system. Results are provided for entertainment and personal reflection only.
How the Moon Sign Calculator works
Provide your date of birth and, where relevant, your time and location. The Moon Sign Calculator uses this to compute your astrological data.
Your personalised result is calculated instantly using established astrological systems.
Review the interpretation provided. Revisit with different dates or parameters to compare readings.
