Rahu Kaal: what it is and how to use it

Rahu Kaal (also written Rahu Kalam or Rahukalam) is a period of about 90 minutes every day that is traditionally considered inauspicious for starting anything new. It is followed very widely in South India and increasingly across the country, especially for travel, purchases, interviews and signing documents.

Why is Rahu Kaal avoided?

In Vedic astrology Rahu is a shadow planet linked with confusion, obstacles and unexpected turns. The period it rules each day is believed to bring delays to anything begun within it. Work that is already underway can continue normally.

How Rahu Kaal is calculated

The time from your local sunrise to sunset is divided into 8 equal parts. Rahu Kaal is one of these parts, and which one depends on the weekday:

DayPart of the dayTypical time (6 am sunrise, 6 pm sunset)
Monday2nd7:30 to 9:00 am
Tuesday7th3:00 to 4:30 pm
Wednesday5th12:00 to 1:30 pm
Thursday6th1:30 to 3:00 pm
Friday4th10:30 am to 12:00 pm
Saturday3rd9:00 to 10:30 am
Sunday8th4:30 to 6:00 pm

The typical times are only a guide. Your real Rahu Kaal shifts with your sunrise and sunset, which change with the season and your location. A Rahu Kaal for Mumbai can differ from Kolkata by about half an hour.

What is fine during Rahu Kaal

Rahu Kaal, Yamaganda and Gulika

Rahu Kaal has two close relatives that are also calculated from the 8 parts of the day: Yamaganda and Gulika Kaal. Many people avoid all three for new beginnings. See Yamaganda, Gulika and Dur Muhurtam explained.

In Tamil Nadu and Kerala, Rahu Kalam is printed in every daily calendar and widely respected. In Karnataka and Andhra Pradesh, Rahu Kala is equally common. In North India it has become more popular through TV and apps.

Frequently asked questions

Is Rahu Kaal at night too?

The commonly used Rahu Kaal is a daytime period. Some traditions also calculate a night Rahu Kaal, but most daily calendars show only the day period.

Can I travel if I left before Rahu Kaal started?

Yes. Traditionally it is the start of the journey that matters. If you set out before Rahu Kaal begins, you can continue.

Why is my Rahu Kaal different from my friend's in another city?

It is calculated from local sunrise and sunset, which differ between cities.
