Nakshatra calculator
Your janma nakshatra is the lunar mansion the Moon occupied at birth. Find it, with its pada and lord.
Nakshatra and pada
The zodiac is divided into 27 nakshatras of 13°20′ each, and every nakshatra into four padas of 3°20′. Your birth nakshatra and pada come from the Moon's exact longitude at birth.
The Moon moves through a nakshatra in about a day, so the birth time matters more here than for your rashi.
Why it matters
The lord of your birth nakshatra starts your Vimshottari dasha sequence, and how far the Moon had travelled through it sets how much of that first dasha was left at birth. Nakshatras are also the basis of kundli matching.
