How the nakshatra is located
The zodiac is divided into twenty-seven nakshatras of 13°20′ each, and yours is whichever one held the Moon at your birth — measured on the sidereal zodiac, with the Lahiri ayanamsa subtracted from the tropical longitude. Each nakshatra is quartered into four padas, so the pada narrows the position to 3°20′, and the ruling planet follows the nine-graha cycle beginning at Ketu.
