Calculation of Maha Dasha Since each nakshatra extends to 13°20’ (800’) of the arc of the zodiac, the number of years allotted will be equated. Hence we need to find out the elapsed longitude of the Moon in a particular star to find out the balance of dasha for the native. Hence equating the full extent of a star (800’) of arc to the full term granted to the lord of the nakshatra, we can work out the balance period equal to the balance of the star yet to be covered by the Moon. We will understand the concept by taking one example. A native is born on 18 Sep 2014 at 8:30 AM. First, find out the longitude of the Moon in a sign. In this case, Moon is posited with a longitude of 23°56’ in the Gemini sign. The nakshatras or stars belonging to the Gemini sign are Mrigasira, Ardra, and Punarvasu. The first 20 degrees are covered by Mrigasira & Ardra and the remaining 10° will be covered by 3 quarters (padas) of Punarvasu star. Therefore it is understood that the Moon is posited in P...
