According to Vedic astrology, certain parts of the day, called Rahu Kalam, are inauspicious periods and one should not undertake any auspicious work during these periods – especially any new undertaking.
Rahukalam differs from place to place depending on Sun-rise & Sun-set time. The day duration from Sun-rise to Sun-set, at a particular location, is divided into eight equal parts. There is no Rahu Kalam during the first period of any weekday. On Monday it falls on the 2nd period, Saturday 3rd period, Friday 4th period, Wednesday 5th period, Thursday 6th period, Tuesday 7th period & Sunday 8th period.
The following are the details of the Rahukalam (also known as rahukal or rahu kal) periods in in operation during the various week days. This is based on 6:00 AM local Sun-rise time and 6:00PM local Sun-set time. If the Sun-rise and Sun-set times are different, you can take the Day duration, divide it in to 8 equal parts and apply the above given formula.
Since the Raahu Kalam is dependent on the Sun-rise and Sun-set times of your particular location, you must calculate it for each day using the bellow method.
Your local Sun-rise & Sun-set times are usually given in the local news papers.
