Today's Nakshatra Calculator

A nakshatra is a lunar mansion - one of 27 equal divisions of the ecliptic, each spanning 13 degrees 20 minutes. A zodiac sign (Rashi) is one of 12 divisions of 30 degrees each. The key difference is that nakshatras are based on the Moon's daily position, while Rashis provide the broader solar-month framework. Every Rashi contains exactly 2¼ nakshatras. Nakshatras offer more nuanced, day-by-day insight than Rashis. In Vedic astrology, your birth nakshatra (Janma Nakshatra) - the nakshatra where your Moon was at birth - is considered even more significant than your Moon sign for personality analysis and timing calculations.

The Moon's nakshatra is calculated by dividing the Moon's sidereal longitude by the span of one nakshatra (13°20' = 13.333°). Nakshatra number = floor(Moon's sidereal longitude × 27 / 360). The Moon's sidereal longitude is obtained by converting its tropical (seasonal) longitude to sidereal by subtracting the Lahiri ayanamsa (approximately 23.85° in 2024, increasing by about 50.3 arcseconds per year). Our calculator performs this conversion automatically using Jean Meeus's precise lunar position algorithm.

Each nakshatra is divided into 4 equal quarters called padas (feet), each spanning 3 degrees 20 minutes. The padas correspond to the 4 signs of the Navamsa (D9) chart, cycling through Aries, Taurus, Gemini, Cancer for the first nakshatra, then Leo, Virgo, Libra, Scorpio for the second, and so on. Pada 1 corresponds to the Dharma (Aries) qualities, Pada 2 to Artha (Taurus), Pada 3 to Kama (Gemini), and Pada 4 to Moksha (Cancer) - though this shifts as you go through the nakshatras. In naming ceremonies (Namakarana), the pada determines the first syllable of the traditional Vedic name.

The most universally auspicious nakshatras for ceremonies are: Rohini (ruled by Moon - fertility, abundance, beauty), Uttara Phalguni (Sun - all-round prosperity), Uttara Ashadha (Sun - victory, invincibility), Uttara Bhadrapada (Saturn - depth, wisdom, stability), Pushya (Saturn - nourishment, the 'king of nakshatras'), Hasta (Moon - skill, craftsmanship), Shravana (Moon - learning, listening, Vishnu's nakshatra), and Revati (Mercury - completion, protection, journeys). Ancient texts rate Pushya as the best nakshatra for ceremonies because of its nourishing, stabilizing quality - except for marriages, where Pushya is traditionally avoided.

Gana (temperament group) is crucial in Vedic marriage compatibility (Ashtakoot matching). Deva (divine) gana nakshatras: gentle, idealistic, spiritual - Ashwini, Mrigashira, Punarvasu, Pushya, Hasta, Swati, Anuradha, Shravana, Shatabhisha, Revati. Manushya (human) gana nakshatras: balanced, practical - Bharani, Rohini, Ardra, Purva Phalguni, Uttara Phalguni, Purva Ashadha, Uttara Ashadha, Purva Bhadrapada, Uttara Bhadrapada. Rakshasa (demonic) gana nakshatras: intense, determined, unconventional - Krittika, Ashlesha, Magha, Chitra, Vishakha, Jyeshtha, Mula, Dhanishtha. For marriage, Deva-Deva is ideal; Manushya-Manushya is good; Deva-Manushya is acceptable; Rakshasa combinations require careful consideration.

Nadi is one of the 8 factors (Ashtakoot) used in Vedic marriage compatibility, and it carries the highest weight (8 points out of 36). The three nadis are Vata (air), Pitta (fire), and Kapha (water) - reflecting the Ayurvedic constitution. Each of the 27 nakshatras belongs to one of the three nadis. If a couple's Janma Nakshatras belong to the same Nadi, it is called Nadi Dosha - considered the most serious incompatibility, traditionally associated with health problems, separation, or the death of one partner. However, many exceptions and cancellations (Nadi Dosha parihara) exist, so a qualified astrologer should always be consulted.

The Moon remains in one nakshatra for approximately 24–25 hours on average. Since the Moon travels 360° in roughly 27.3 days, it covers about 13.2° per day - slightly less than one nakshatra span (13.33°). The exact duration varies because the Moon's orbit is elliptical: when near perigee (closest to Earth), the Moon moves faster and stays in a nakshatra for only about 21–22 hours; near apogee (farthest from Earth), it moves more slowly and can remain in a nakshatra for up to 26–27 hours. This is why the Janma Nakshatra - the nakshatra where the Moon was at the exact time of birth - requires precise birth time for accurate calculation.

Abhijit is an extra nakshatra sometimes counted in addition to the standard 27, making a total of 28. It spans approximately 6°40' to 10°53' in Capricorn (near Uttara Ashadha) and corresponds to the star Vega (Alpha Lyrae), one of the brightest stars in the sky. Abhijit is considered extremely auspicious - associated with Lord Brahma and invincibility. In Vedic mythology, it is said that Indra performed his most important ceremonies in Abhijit muhurat. However, in standard Jyotish practice (nakshatra system for horoscopes, dasha calculations, and compatibility), only 27 nakshatras are used. Abhijit is primarily referenced for muhurat (auspicious timing) selection.
