Rahu kaal

In Indian Astrology, each day of the week has been assigned its respective

ruling planet viz. Monday is ruled by Moon, Tuesday by Mars etc. However,

Rahu and Ketu have not been given any specific day as they are treated as

nodes. However, Rahu and Ketu are given one and half hours time in a day

resulting three hours for Rahu and Ketu in which they can cast their malefic

influence since Rahu is a natural malefic.

Rahu Kalam (Rahu Kaal) is an inauspicious period of time for a particular day.

In other words, Rahu Kalam is the time during which Rahu seizes the

opportunity for influence. During this time one should avoid any auspicious

work like starting new business or project, buying expensive items,

investments, business transactions, journeys, meetings, interviews etc. It is

believed that any thing lost during Rahu Kalam is never found.

Rahu Kaal is one-eighth part of the difference between the Sunset and

Sunrise time of a particular place for a specific day of the week. The reason

for its 8th part is that in some Indian astrology systems, Rahu is considered

to be the 8th planet.

To calculate Rahu kalam or Rahu kaal, first find the local Sun-rise time and

sun-set time of the place. This can be found from a local panchang or your

local newspaper. Next divide the difference between the two time periods

into 8 equal parts. There is no Rahu Kalam during the first period of any

weekday. In other words, it is never just after sunrise. From Monday to

Sunday the period of Rahu Kaal or Rahu kalam for each week day is then

calculated as described below:

On Monday Rahukalam falls on the 2nd period

    Saturday                              3rd period

    Friday                                  4th period

    Wednesday                           5th period

    Thursday                              6th period

    Tuesday                               7th period

    Sunday                                 8th period
