What is Rahu Kalam?
Rahu Kalam (also spelled Rahu Kaal or Rahu Kala) is one of the three inauspicious periods in the Hindu day — the other two being Yamagandam and Gulika Kalam (Kuligai). It is the 90-minute period each day ruled by Rahu, the ascending lunar node in Vedic astrology.
Starting any new and important activity — signing contracts, making investments, travel, medical procedures, or auspicious ceremonies — during Rahu Kalam is traditionally avoided in Hindu astrology.
