The combined longitudes of the Sun and the Moon is called a Nithya Yoga. There are 27 Nithya Yogas based on the 27 constellations which tenant the Ecliptic in Hindu Astrology. The calculation of Nithya Yoga is simple. Add the longitude of the Moon to the longitude of the Sun, divide it by 13 degrees 20 minutes and you get the Nithya Yoga.
