Nakshatras: The 27 Divisions Behind Your Chart
Twelve signs are the coarse grid. Twenty-seven nakshatras are the one Indian astrology actually works in.
A finer division of the same sky
The zodiac is a circle of 360°. Divide it by twelve and you get the signs, each 30° wide. Divide the same circle by twenty-seven and you get the nakshatras, each about 13°20′.
They are older than the sign system in Indian use, and a great deal of Jyotish is built on them rather than on signs: your dasha sequence, much of compatibility matching, and the traditional timing of ceremonies.
Why the finer grid matters
Two people can share a Moon sign and have completely different Moon nakshatras, because each sign contains about two and a quarter of them. Nearly everything predictive in Jyotish keys off the nakshatra, not the sign.
Each nakshatra is further split into four padas of 3°20′, which is how the same nakshatra produces different readings depending on where in it a planet falls.
The one that matters most
When someone refers to “your nakshatra” without qualification, they almost always mean the nakshatra your Moon occupied at birth. That is the one that starts your Vimshottari dasha sequence and the one used in matching.
The Moon moves about thirteen degrees a day — roughly one nakshatra — so a birth date alone will not tell you. You need the chart.
Common questions
How many nakshatras are there?
Twenty-seven, each about 13°20′ of the zodiac, and each divided into four padas.
Is a nakshatra the same as a zodiac sign?
No. Signs divide the circle into twelve; nakshatras divide the same circle into twenty-seven. A sign contains a little over two nakshatras.
How do I find my nakshatra?
From your birth chart. The Moon covers roughly one nakshatra a day, so you need the date, time and place rather than just the date.
