Western Moon Sign Calculator — Tropical, Not Vedic

Your moon sign is the zodiac sign the Moon occupied at the moment you were born. This calculator returns the Western version: the Moon's sign in the tropical zodiac (measured from the equinoxes), with the exact degree and the house the Moon occupies in the traditional whole-sign chart.

The planet is the same — both are the Moon's sign at your birth — but the coordinate system differs. This page computes the tropical zodiac (Western); a rashi is the Moon's sign in the sidereal zodiac, measured against the fixed stars with the Lahiri ayanamsa. Because the two zodiacs are currently offset by about 24 degrees and each sign spans 30 degrees, your Western moon sign can be one sign ahead of your rashi.

No. In Indian astrology 'moon sign' means the rashi — the Moon's sign in the sidereal zodiac (Lahiri ayanamsa), which is what Vedic charts, horoscope matching and most Indian horoscope apps use. This calculator is Western: it uses the tropical zodiac, so the result can differ from your rashi by about a sign. The Rashi Calculator on this site computes the Vedic version.

The Moon moves through the zodiac faster than any other classical planet — roughly one sign every two and a quarter days. If you were born on a day the Moon changed signs, the exact birth time and place decide which side of the boundary you fall on, so enter them as accurately as you can.

Often the date alone is enough, because the Moon stays in one sign for about two and a quarter days. The birth time matters when the Moon changed signs on your birth date, and it is required for the house shown in the result — the house is counted from your ascendant, which changes roughly every two hours.

No — it returns a single placement: the Moon's sign, degree and house. For the complete traditional Western chart — all seven classical planets, the four angles, sect, and the dignities and condition with their classical citations — use the Birth Chart Calculator.
