Term
Yamagandaयमगण्ड
Inauspicious period
A daily inauspicious window, traditionally avoided for auspicious activities and travel. Calculated by the same 8-part day division as Rahu Kalam, with the Yamaganda portion varying by weekday according to classical tables.
Yamaganda — associated with Yama, the lord of time and restraint — is one of the three inauspicious day-parts, alongside Rahu Kalam and Gulika Kalam. It is the window tradition most specifically associates with avoiding travel and beginning auspicious work.
It is found by the same method as Rahu Kalam: the daytime, sunrise to sunset, is divided into eight equal parts, and one part is assigned to Yamaganda by the weekday. The table is its own — distinct from the Rahu and Gulika tables — so on any given day the three periods fall in different parts of the day. Because the parts are fractions of the actual daylight, the timing and length shift with the date and the latitude.
SahiKundli computes the window from the location’s real sunrise and sunset via the Swiss Ephemeris and reports its start and end in local time. As with the other day-parts, it is presented descriptively, as reference information rather than instruction; the Day-part timings entry sets out the full set and the weekday tables.
