Rahukalam: Rahukaalam (also spelled as Rahu Kaalam, Rahu Kaala, Raukaala, Raahu Kaala, Raahu kaal, or Rahu kalam) or the period of Rahu is a certain period of time every day that is considered inauspicious for any new venture according to Indian Vedic astrology.
In India, there is a practice of checking auspicious time for performing any new initiative related to official and personal work. While checking for a good time based on panchang (panchangam in Tamil) and Hora concepts of Vedic astrology, people usually avoid the time of Rahu Kaal (also referred to as Rahukaalam).
This Rahu Kaal / Rahu Kaalam period varies based on the sunrise and sunset timings.
After the daylight, hours are divided into 8 sections. The following is the allocation of time for Rahu Kaalam.
- Sunday – 8th section of 8 divisions
- Monday – 2nd section of 8 divisions
- Tuesday – 7th section of 8 divisions
- Wednesday – 5th section of 8 divisions
- Thursday – 6th section of 8 divisions
- Friday – 4th section of 8 divisions
- Saturday – 3rd section of 8 divisions
In English, the mnemonic phrase is “Mother Saw Father Wearing The Turban Suddenly”
- Mother = Monday (7.30-9.00)
- Saw = Saturday (9.00-10.30)
- Father = Friday (10.30-12.00)
- Wearing = Wednesday (12.00-13.30)
- The = Thursday (13.30-15.00)
- Turban = Tuesday (15.00-16.30)
- Suddenly = Sunday (16.30-18.00)
Yama Gandam: Yama Kandam is calculated by dividing the day hours (from sunrise to sunset) into 8 sections, where each day has 1.5 hours duration allocated to the son of planet Sun ‘Yama’.
This Yama Gandam period varies based on the sunrise and the sunset timings.
