Vyatipata व्यतीपात

Add the sidereal longitudes of the Sun and the Moon, then divide the result into twenty-seven equal parts of 13°20' each. The part the sum falls in is the nitya yoga. Because the sum advances by roughly 14° a day — the Moon's daily motion plus the Sun's — a yoga lasts a little under a day.

Vyatipata occupies the span from 213.33° to 226.67° of that cycle. Like every anga, it can begin and end at any hour, which is why our panchang shows the transition time rather than a bare label.

Vyatipata is one of the nine yogas the muhurta texts treat as afflicted. For most of them only the opening portion is considered seriously bad, and the remainder is workable — Vyatipata and Vaidhriti are the two exceptions, where auspicious work is usually deferred for the whole duration. Where the timing cannot move, practitioners lean on a strong tithi, a favourable nakshatra, or an Abhijit or choghadiya window inside it.
