Rahu Kalam (ராகு காலம்) is a daily inauspicious 90-minute window in Hindu Vedic astrology, ruled by Rahu — the north lunar node. Starting any new venture, business deal, travel, or important activity during Rahu Kalam is traditionally avoided.
The timing changes every day based on the day of the week and local sunrise time. The day from sunrise to sunset is divided into 8 equal parts, and Rahu Kalam occupies one of those slots depending on the weekday. On Monday it is the 2nd slot, on Saturday the 3rd, and so on.
