Rahu Kalam Myths, Realities and Time Calculation

Are you afraid of starting something during “Rahu kalam”? Here is why you should, here is why you shouldn’t!!

Rahu kalam raises many eyebrows. The word Rahu creates panic in many. Shani and Rahu are two dreaded words in believers of astrology and also who are superstitious. In reality there is nothing to worry about Rahu kalam.

What is Rahu kalam?

As you know Rahu is not a planet but its the shadow on the moon. As moon is rotating around earth everyday its shadow is cast at different timings on different days. It is similar to the shadows that we see of ourselves while walking under the sun. So the timing of that shadows is considered to be inauspicious for starting any important work.

What are Rahu kalam timings?

See any calendar you will see the following timings
Sunday 4.30pm to 6pm
Monday 7.30am to 9am
Tuesday 3pm to 4.30pm
Wednesday 12noon to 1.30pm
Thursday 1.30pm to 3pm
Friday 10.30am to 12noon
Saturday 9am to 10.30am

Is Rahu kalam inauspicious?

The simple answer is No. Many board exams start on Mondays at 9am and millions of students start from their homes during the rahu kalam time of 7.30am to 9am to reach exam centers. Are they not writing their exams well and scoring high grades? So, rahu kalam is being evil and inauspicious is just a myth. It is just a shadow and shadows are never bad.

Then why do people fear Rahu Kalam?

Like Shani, Rahu is a planet who teaches lessons in a harsh way. If your intentions are bad, you will be immediately punished. If you do anything good also with a evil intention, you would get it back in a negative way. And Rahu like shani has the habit of teaching any lesson of life in the harshest possible way so that it remains in mind for ever. So, if your intentions are clear and if your conscious is clean you need not worry at all. Rahu kalam is like any other time of the day.

So, should we disregard and reject Rahu Kalam?

Again the answer is No. A belief always has a reason and logic and we cannot disregard it. If anyone believes for whatever reason in Rahu kalam, they are entitled to their beliefs. But the question is are they following it right?

Are they following it right?

No, they are not. The above mentioned Rahu kalam timings are applicable when the day is of 12 hour duration and sun rises at 6am and sets at 6pm. Then each day is divided into 8 parts of 1 hr 30 mins each. Except in the 1st part of the day, everyday shadow will fall on one of the parts.  On Monday you will have Rahu kalam during the 2nd part of the day ie between 7.30 to 9am, Saturday 9am to 10.30am Friday 10.30am to 12 noon, Wednesday 12 noon to 1.30 pm, Thursday 1.30pm to 3pm, Tuesday 3pm to 4.30pm and Sunday rahu kalam is on last part of the day 4.30pm to 6pm. But we know very well, that sun doesn’t rises at 6am everyday nor sets at 6pm every day. So, obviously what you see in your calendar doesn’t apply most of the times.

  1. Amazing analysis! Explained in a very simplified manner. I have a question, why haven’t astrologers followed or rather practiced it.

    1. Two things Ma’am
      1. Rahukalam depends on sunrise and sunrise timings are different for different places in India for different months. So a calendar that goes everywhere cant have it. So they give a generalized one.
      2. But when you consult your personal astrologer for right timing for doing something he checks the exact rahukalam timings and will advice you.

    1. Not Always. Only when advised by a competent astrologer or when you are going for a critical task during that period it is advised. But it cannot completely remove the ill effects.
