Yamagandaयमगण्ड

Similar in spirit to Rahu Kaal — no classical text ranks one as more severe than the other, though Rahu Kaal tends to be more widely and strictly observed in practice. Still worth avoiding for major decisions.

One full 1/8th-of-daytime slot, positioned according to its own weekday-based table (distinct from Rahu Kaal's).

Yamaganda is named for Yama, the Vedic god of death and dharma. It is one of three daily inauspicious windows (alongside Rahu Kaal and Gulika Kaal) that occupy 1/8th of the daytime each. Classical texts associate Yamaganda with Yama's influence over endings, finality, and the consequences of past actions — making it traditionally unfavorable for initiating anything whose outcome you want to be positive and lasting.

Both Rahu Kaal and Yamaganda are 1/8th-of-daytime slots, but they fall at different times — each has its own weekday-based position table. No classical Sanskrit muhurta text grades one as more severe than the other in principle — Rahu Kaal is simply more widely and strictly observed in real-world practice, which is a matter of custom rather than a classical severity ranking. In practice, both are avoided for the same categories of activity: new ventures, contracts, travel, and auspicious ceremonies.

The same categories as Rahu Kaal: starting new ventures, signing contracts, beginning journeys, making large purchases, performing auspicious ceremonies. The key principle is the same — avoid initiating anything important whose outcome you care about. Ongoing activities are unaffected.
