Jyotiṣa basics
The 27 nakshatras and why your birth star matters
The twelve signs are the zodiac's provinces. The nakshatras are its villages, and Vedic astrology has always preferred to know exactly which village the Moon was standing in when you were born.
The short answer
The sidereal zodiac divides into 27 nakshatras, each spanning 13 degrees 20 minutes, each split into four padas. Your janma nakshatra, or birth star, is the one the Moon occupied when you were born. It seeds your Vimshottari dasha timeline, supplies the naming syllable, sets your gana, and drives several tests of marriage matching.
A finer ruler than the signs
A sign is thirty degrees wide, and the Moon crosses one in a little over two days. That is too coarse for a tradition obsessed with timing. So Jyotiṣa lays a second, older ruler over the same circle, dividing it into 27 mansions the Moon visits in roughly one day each. Two people born three days apart share a Moon sign yet carry different birth stars, different dasha clocks, and by the tradition's lights, different temperaments.
What your birth star actually governs
- Your dasha clock. The lord of your janma nakshatra opens your Vimshottari sequence, and how far the Moon had walked through the star fixes the balance of that first period. Two charts differ in nothing so much as this.
- Your name, traditionally. Each pada carries a syllable, which is why a pandit at a naming ceremony asks for the birth star before suggesting anything.
- Your gana. Every nakshatra belongs to the deva, manushya, or rakshasa group, one of the heavier tests in marriage matching.
- Matching arithmetic. The Tara and Yoni kutas count and pair birth stars directly. The same star scores differently against different partners, which is why no fixed list of lucky stars survives contact with a real milan.
- Muhurta and daily practice. The Moon's current nakshatra colours the day's panchang, and certain rites wait for certain stars.

Common questions
How do I find my nakshatra?
It needs your birth date, time, and place, because it is the Moon's exact position that decides. Cast a free chart and the kundli names the star and pada in the panchang card.
What is a pada, exactly?
A quarter of a nakshatra, 3 degrees 20 minutes wide. Padas refine readings and supply the traditional naming syllable.
Which nakshatras suit each other for marriage?
It depends on the pairing, not the star alone. The Tara and Yoni tests score your two stars against each other, so run the milan rather than consulting a fixed list.
Is there really a 28th nakshatra?
Abhijit, used in muhurta work. It borrows its span from Uttara Ashadha and Shravana and stays out of the dasha scheme.
