Find your Sun sign and Moon sign — Western (tropical) astrology — from your date, time, and place of birth.
Sun sign is a calendar-date lookup. Moon sign uses a compact Moon-position formula (accurate to within a few arcminutes) — precise enough for Sun/Moon sign purposes, but not a substitute for a full professional birth chart reading.
Your Sun sign is a simple calendar-date lookup, but your Moon sign requires knowing your exact birth time and place, this tool calculates both using Western tropical astrology conventions.
Sun sign is a calendar-date lookup, since the Sun’s position along the zodiac at any given calendar date is essentially fixed year to year. Moon sign uses a compact Moon-position formula (accurate to within a few arcminutes), since the Moon moves through the zodiac roughly 13 times faster than the Sun, meaning your Moon sign depends on your specific birth time and location, not just your birth date.
The Sun’s zodiacal position on any given date is the same everywhere on Earth, which is why a Sun sign lookup only needs your birth date. The Moon, moving much faster through the zodiac, can change signs multiple times within a single day, so pinning down your Moon sign requires your exact birth time converted to the correct local time zone, which is why place of birth becomes necessary for that specific calculation.
The Sun’s position along the zodiac on a given calendar date is essentially the same everywhere on Earth, so a Sun sign lookup only needs your birth date, unlike the faster-moving Moon.
The Moon moves through the zodiac roughly 13 times faster than the Sun and can change zodiac signs multiple times within a single day, so an accurate Moon sign requires your precise birth time converted to the correct local time zone based on your birth location.
This tool uses Western (tropical) astrology conventions for both Sun and Moon sign, which differs from Vedic (sidereal) astrology’s Nakshatra and Rashi system.
