Free Vedic Astrology Tool
Your Rashi is your Vedic Moon sign — the sidereal zodiac sign the Moon occupied at the exact moment you were born. Unlike your Western sun sign, Rashi is calculated using the Moon's position and the Lahiri ayanamsa, and it's the foundation of Vedic astrology, daily rashifal readings, and nakshatra-based matchmaking. Enter your full birth details below to find your Rashi and Nakshatra instantly — free, with no signup.

In Vedic (sidereal) astrology, your Rashi is determined entirely by where the Moon was positioned in the zodiac at your exact birth moment — not the Sun, as in Western astrology. Because the Moon moves through the entire zodiac in about 27.3 days, spending roughly 2.25 days in each sign, your Rashi is a much more precise, personal marker than a sun sign that stays fixed for a full month.
Vedic astrology also uses a different reference frame than Western astrology: the sidereal zodiac, corrected for the slow precession of the Earth's axis using an offset called the ayanamsa (this calculator uses the widely-adopted Lahiri ayanamsa). This is why your Rashi often differs from your Western Moon sign by one sign — both are 'correct,' just measured against different starting points in the sky.
Alongside your Rashi, this calculator also reveals your Nakshatra — one of the 27 lunar mansions the Moon passes through, each spanning 13°20' of the zodiac and further divided into four padas (quarters). Your Nakshatra and its ruling planet are central to Vimshottari dasha calculations, muhurat (auspicious timing), and traditional Vedic matchmaking (Ashtakoot/guna matching).

We calculate the Moon's real ecliptic longitude at your exact birth moment using astronomical ephemeris data, then convert it from the tropical to the sidereal zodiac using the Lahiri ayanamsa.
The sidereal Moon position determines your Rashi (one of 12 signs) and Nakshatra (one of 27 lunar mansions), along with its pada and ruling planet.
Rashi is the Vedic (sidereal) zodiac sign occupied by the Moon at the moment of your birth. It's often called your 'Moon sign' and is considered the most important placement in Vedic astrology — more central than the Sun sign used in Western astrology.
Western astrology uses the tropical zodiac, based on the seasons, while Vedic astrology uses the sidereal zodiac, based on the actual position of stars. Over centuries, the slow precession of Earth's axis has created roughly a 24-degree gap (the ayanamsa) between the two systems, which is why the same birth moment can map to different signs in each system. Also note: Rashi is based on the Moon's position, while a Western 'zodiac sign' usually refers to the Sun's position — they measure different placements entirely.
A Nakshatra is one of 27 lunar mansions or constellations that the Moon passes through during its orbit, each spanning 13°20' of the zodiac. Your birth Nakshatra, along with its pada (quarter) and ruling planet, is used for Vimshottari dasha timing, choosing auspicious dates (muhurat), and traditional Vedic horoscope matching.
It helps but isn't required. The Moon moves about 13 degrees per day, so even without an exact time, your Rashi is almost always correctly identified using a noon-time approximation. An exact birth time matters more for Nakshatra pada precision near sign boundaries and for house-based chart details.
