Yamagandam (யமகண்டம், also Yamakantam) is one of the three daily inauspicious periods in the South Indian Panchang tradition, alongside Rahu Kalam and Kuligai Kalam. It is the period governed by Yama — the deity of death and cosmic justice in Hindu mythology. During Yamagandam, traditional practice advises avoiding the initiation of new and important activities.
Like Rahu Kalam, Yamagandam is calculated from the local sunrise time. The daytime hours (sunrise to sunset) are divided into 8 equal octaves, and Yamagandam occupies one octave based on the weekday. The weekday table (for approximate 6 AM sunrise) is: Sunday=12–1:30 PM, Monday=10:30 AM–12 PM, Tuesday=9–10:30 AM, Wednesday=7:30–9 AM, Thursday=6–7:30 AM (around sunrise), Friday=3–4:30 PM, Saturday=1:30–3 PM.
Yamagandam is specifically avoided when beginning travel, starting new business, performing auspicious ceremonies, or making major decisions. This is because Yama (also called Dharmaraja) is associated with death and endings — not auspicious beginnings. The period is considered unfavourable for starting things you want to see successfully completed.
Unlike Rahu Kalam (which is extremely widely observed), Yamagandam is somewhat less known outside of traditional South Indian households and astrology practitioners. However, detailed Panchangams — especially Tamil and Telugu almanacs — list all three inauspicious periods (Rahu Kalam, Yamagandam, and Kuligai) as essential daily entries.
As with all Panchang timings, Yamagandam varies by location because it is anchored to local sunrise. A Yamagandam time calculated for Chennai is different from the time in Mumbai, Delhi, or Bengaluru on the same day. Always use a location-specific calculator for accuracy when planning important activities.
