Rahu Kaalam:

Rahu Kaal is considered the most inauspicious time of the day. Vedic astrology states that Rahu kaal covers 90 minutes a day and this time is ruled by Rahu, one among Navagrahas and that is why it is considered inauspicious to perform any important and auspicious work during this time.

It is believed that anything started and performed during this time does not give beneficial results and often leads to failure. But After the first 1 hour of the Rahu period, the last half hour is the ‘Amrutha Rahu’ period. It is said that doing anything during this time will bring benefits. The benefits are cumulative.

After the first 1 hour of the Rahu period, the last half hour is the ‘Amritha Rahu’ period. It is said that doing anything during this time will bring benefits. The benefits are cumulative.

Suvarnabhanu, a demon disguised as God, took a drop of nectar from Tirumal’s hand. Then the Puranas say that the head and body of Rahu became Ketu after being pointed by Sun and Moon and in the hands of Thirumal who was incarnated as Mohini, his head was chopped off with an agapai and Puranas say that Rahu, the head and body, became Ketu. The last half hour of the Rahu period is beneficial because of tasting that one drop of nectar. That is called the ‘Amrita Rahu period’.

Yamagandam:
