The Moon moves roughly 13 degrees and 20 minutes across the sky each day, and Vedic astrology splits the zodiac into 27 equal slices of exactly that span. These slices are the nakshatras, or lunar mansions. Where the Moon sits at the moment of birth gives you your Janma (birth) nakshatra, which many practitioners treat as more personal than the Sun sign. This primer covers what the 27 nakshatras are, how they are structured, and what they are used for. AstroAsk has a full guide for each one if you want to go deeper.

Twelve signs of 30 degrees each give 360 degrees; divide that by 27 and you get 13 degrees 20 minutes per nakshatra. Each one carries a ruling planet, a presiding deity, and a symbol that hints at its nature. For example, the planetary rulers cycle through Ketu, Venus, Sun, Moon, Mars, Rahu, Jupiter, Saturn, and Mercury three times across the 27. The first nakshatra is Ashwini and the last is Revati. Because they are tied to the Moon rather than the Sun, your nakshatra can differ markedly in flavour from your Western Sun sign.
How nakshatras are used
Each nakshatra is split into four padas (quarters) of 3 degrees 20 minutes, which sharpen the reading and feed naming traditions and Navamsa analysis. Practical uses include personality and temperament profiling, choosing a baby name (the first syllable is often drawn from the birth pada), the Vimshottari dasha system that times life periods from the Moon nakshatra, and Ashtakoota matching for marriage compatibility. Electional astrology (muhurta) also leans on the day nakshatra to pick favourable timing.
Key takeaways
- There are 27 nakshatras, each spanning exactly 13 degrees 20 minutes of the zodiac.
- Your Janma nakshatra is set by the Moon position at birth, not the Sun.
- Every nakshatra has a ruling planet, a deity, a symbol, and four padas.
- Nakshatras drive naming, the Vimshottari dasha timeline, and marriage matching.
