The nitya yoga is the fifth limb of the panchanga: twenty-seven named combinations of the Sun's and Moon's positions, each colouring the day auspicious, mixed, or harsh. It is unrelated to the birth-chart yogas that share the name. The word 'yoga' is used in two quite different ways in astrology, and this is the almanac one — a daily quality, not a chart combination. It is found by adding the Sun's and Moon's positions together and dividing the zodiac into twenty-seven equal parts, one named yoga for each day from Vishkambha to Vaidhriti. Most simply tint the day's mood, but a few — Vyatipata and Vaidhriti above all — are marked as harsh and set aside for anything new or important. Because it depends on both luminaries at once, the nitya yoga is a quick reading of how the Sun and Moon are getting along on a given day, and it takes its place beside the tithi, vara, karana and nakshatra as one of the five limbs that together make up the panchanga, the traditional daily almanac.
The twenty-seven yogas from Vishkambha to Vaidhriti derive from the SUM of the Sun's and Moon's longitudes in 13°20′ steps; Vyatipata and Vaidhriti head the list of those avoided for new undertakings.
