Moon Sign Calculator
Enter your birth date, time and place to find your moon sign. The moon sign governs your emotional world and intuition.
Astrology is not a scientific discipline; this tool is for entertainment and personal exploration. The calculation is based on astronomical formulas and gives approximate results.
What Is the Moon Sign and Why Is It Calculated?
The moon sign is the zodiac sign the Moon occupied at the moment of your birth. While the sun sign changes once a year, the Moon moves through a sign roughly every 2.5 days — so two people with the same sun sign can have completely different moon signs. According to astrology, the sun sign represents the identity you project outward, while the moon sign governs how you process emotions, what environment makes you feel safe, and your instinctive reactions.
Discovering your moon sign reveals the complementary emotional layer of your sun sign. A Sun Leo + Moon Virgo combination describes someone who appears charismatic on the outside but operates with precision and analytical thinking inside. Accurate calculation of the moon sign is important for this holistic perspective.
How Does the Moon Sign Calculator Work?
Required Inputs (Date, Time, Location)
- Birth date — day, month and year
- Birth time — if unknown, check the "I don't know my birth time" option
- Birth place — country and city; UTC offset is applied automatically
The Calculation Method Behind the Scenes
The tool calculates the Moon's ecliptic longitude via Julian Day Number using formulas from Jean Meeus's Astronomical Algorithms. The standard UTC offset of the selected city is applied; daylight saving time is not included. Since the Moon moves approximately 0.5° per hour, birth time and location are critical for an accurate result.

Tips for Interpreting Your Moon Sign Accurately
The moon sign result forms a meaningful whole only when evaluated alongside your sun and rising signs. Verify your birth time from your birth certificate — since the Moon can change signs between morning and night, even a small difference can yield a very different result. If you were born outside Turkey, select your birth city from the list; the UTC offset is applied automatically. For a definitive astrological interpretation, consulting an astrologer who knows both your moon and rising sign is recommended.
