Yogaयोग
Sun-Moon combination
One of 27 daily yogas computed from the combined longitude of the Sun and Moon. Each yoga spans 13°20' of combined motion and carries a traditional quality — from Vishkumbha (inauspicious) to Siddhi and Shubha (auspicious). Distinct from the yogas formed by planetary combinations in a birth chart.
The nitya yoga — the daily yoga of the panchanga — is one of 27, each given a name and a traditional quality, from the inauspicious Vishkumbha at the start of the cycle to favourable ones such as Siddhi and Shubha. It is a property of the day, not of a person.
A point worth stating plainly: this is not the same as the “yogas” of a birth chart — the planetary combinations such as Gajakesari or Raja yogas. They share a name (both mean “union”) but nothing else. The panchanga yoga is a single daily value derived purely from the Sun and Moon.
SahiKundli computes it from the sum of the sidereal longitudes of the Sun and Moon — where the tithi uses their difference. That combined longitude is divided into 27 bands of 13°20' each; the band occupied at sunrise is the day’s yoga, and its end time is found by bisection on the combined longitude, shown in the location’s timezone. The traditional quality is reported descriptively, as reference, not instruction.
