Rahu Kalam Yamagandam and Gulika Kalam
Share this post
Almost every Indian calendar and panchang prints three daily time windows: Rahu Kalam, Yamagandam and Gulika Kalam (Kuligai). Each lasts about an hour and a half, and families traditionally avoid them when starting something important. This guide shows how they are worked out, gives the table for every weekday, and explains how to use them without anxiety.
The basic method: eight parts of the day
All three are found the same way:
- Take the local sunrise and sunset for the day.
- Divide the daylight into eight equal parts (octants). With a 12-hour day, each part is 1 hour 30 minutes.
- Each weekday assigns one of the eight parts to Rahu, one to Yamagandam and one to Gulika.
| Weekday | Rahu Kalam part | Yamagandam part | Gulika Kalam part |
|---|---|---|---|
| Sunday | 8th | 5th | 7th |
| Monday | 2nd | 4th | 6th |
| Tuesday | 7th | 3rd | 5th |
| Wednesday | 5th | 2nd | 4th |
| Thursday | 6th | 1st | 3rd |
| Friday | 4th | 7th | 2nd |
| Saturday | 3rd | 6th | 1st |
Notice the patterns: Gulika moves one part earlier each day from Sunday to Saturday, and Yamagandam does the same from Sunday to Thursday before jumping to the 7th part on Friday.
Timings for a 6 am to 6 pm day
Most printed calendars assume sunrise at 6:00 and sunset at 18:00. On that basis:
| Weekday | Rahu Kalam | Yamagandam | Gulika Kalam |
|---|---|---|---|
| Sunday | 16:30 - 18:00 | 12:00 - 13:30 | 15:00 - 16:30 |
| Monday | 07:30 - 09:00 | 10:30 - 12:00 | 13:30 - 15:00 |
| Tuesday | 15:00 - 16:30 | 09:00 - 10:30 | 12:00 - 13:30 |
| Wednesday | 12:00 - 13:30 | 07:30 - 09:00 | 10:30 - 12:00 |
| Thursday | 13:30 - 15:00 | 06:00 - 07:30 | 09:00 - 10:30 |
| Friday | 10:30 - 12:00 | 15:00 - 16:30 | 07:30 - 09:00 |
| Saturday | 09:00 - 10:30 | 13:30 - 15:00 | 06:00 - 07:30 |
A popular way to remember the Rahu Kalam order from 7:30 onwards is "Mother Saw Father Wearing The Turban Suddenly": Monday, Saturday, Friday, Wednesday, Thursday, Tuesday, Sunday.
Why your own sunrise matters
Sunrise and sunset change through the year and from place to place, so the real windows drift from the 6-to-6 table, sometimes by 30 minutes or more. The correct method always uses the actual sunrise and sunset.
Worked example (Monday): sunrise 6:20, sunset 18:12. Daylight is 11 hours 52 minutes = 712 minutes. One part is 712 / 8 = 89 minutes.
- Rahu Kalam (2nd part): 6:20 + 89 min = 7:49 to 9:18.
- Yamagandam (4th part): 6:20 + 3 x 89 min = 10:47 to 12:16.
- Gulika Kalam (6th part): 6:20 + 5 x 89 min = 13:45 to 15:14.
Compare these with the fixed table (7:30-9:00, 10:30-12:00, 13:30-15:00): the difference is real. Panchangs made for a particular city, and astrology software that calculates sunrise for your location, give the accurate windows. Some traditions also mark night-time portions using sunset to the next sunrise, but the daytime windows are the ones in common use.
What each period is traditionally used for
- Rahu Kalam: avoided for beginnings such as starting a journey for an important purpose, signing agreements, opening a business, a house-warming or a wedding ceremony. Many people use it for prayer, and worship of Goddess Durga in Rahu Kalam, especially on Tuesdays and Fridays, is a well-known custom in South India.
- Yamagandam (Emagandam): named after Yama; avoided for auspicious beginnings in the same way.
- Gulika Kalam (Kuligai): ruled by Gulika, a son of Saturn. A traditional belief is that whatever is done in Gulika Kalam tends to repeat. For that reason it is avoided for things you would not want repeated, and some people prefer it for things they would like to recur, such as paying off a debt or buying property. Practices differ by family and region.
Gulika Kalam is a time window and is not the same as the Gulika point placed in a birth chart, although both come from the same idea. The chart point and its twin Mandi are explained in the difference between Gulika and Maandi).
Keeping it in proportion
These three windows are general: they are the same for everyone in a town on a given day. They are useful for timing a beginning, not for judging how a day will go. For a personal check, Muhurtha adds factors based on your own birth chart, such as Tara Bala from your birth star and Chandrashtama from your Moon sign, along with the panchang's tithi and nithya yoga.
If something important must happen during Rahu Kalam, such as a train time, a hospital appointment or an exam, simply go ahead. Ordinary life is not paused by these windows, and no single time factor decides the outcome of honest effort.
Summary
Divide the daylight from sunrise to sunset into eight equal parts. Rahu Kalam is the 8th, 2nd, 7th, 5th, 6th, 4th and 3rd part from Sunday to Saturday; Yamagandam the 5th, 4th, 3rd, 2nd, 1st, 7th and 6th; Gulika Kalam the 7th down to the 1st. Use your own sunrise and sunset for accurate times, avoid these windows for important beginnings, and carry on calmly with everything else.
Frequently Asked Questions (FAQ)
What is Rahu Kalam?
Rahu Kalam is a period of about one and a half hours each day, ruled by Rahu, that is traditionally avoided for starting new and important work. Its position in the day changes with the weekday.
How is Rahu Kalam calculated?
Divide the time from sunrise to sunset into eight equal parts. Rahu Kalam is the 8th part on Sunday, the 2nd on Monday, the 7th on Tuesday, the 5th on Wednesday, the 6th on Thursday, the 4th on Friday and the 3rd on Saturday.
Why is Rahu Kalam different in different cities?
Because it is based on local sunrise and sunset, which change with the place and the season. The fixed 6 am to 6 pm table is only an approximation; for accuracy use your own sunrise and sunset.
Can I do anything during Rahu Kalam?
Yes. Ordinary work, travel already planned and daily routines continue as usual. Tradition only advises not to begin important new undertakings in it. Prayer, especially to Durga, is considered suitable at this time.
