Rahu Kaal vs Barabela: The Mathematics of Amrit Yog and Auspicious Moments

🌐 Read this in: हिन्दी · বাংলা

"Time in itself is neither good nor bad; it was the ancient acharyas who, in seeking the connection between the positions of the planets and stars in the heavens and the life of man, devised the mathematical rules of auspicious and inauspicious moments."

Before beginning any auspicious work, we often open the Panchang to see which hours of the day are auspicious and which are not. In one place we find "Rahu Kaal", in another "Barabela"; somewhere, by nakshatra, "Amrit Kaal", and somewhere else, by weekday, "Amrit Yog". Why such diversity in time-calculation within a single country? Because across the regions of India, distinct traditions of the Panchang have developed. The rules for determining auspicious and inauspicious moments differ considerably between the North Indian Panchang and the Bengali Panjika — and those are what we shall examine today.

North Indian Panchang: Rahu Kaal, Yamaganda and Abhijit Muhurat

In the Panchang of the Hindi belt, the day-span (from sunrise to sunset) is divided into eight equal parts, and certain parts are held to be inauspicious according to the weekday. Each part is roughly an hour and a half — a little longer in summer, a little shorter in winter.

Rahu Kaal: In both the North and South Indian traditions, Rahu Kaal is an inauspicious period. The part of the day-span is fixed by weekday — Sunday the 8th, Monday the 2nd, Tuesday the 7th, Wednesday the 5th, Thursday the 6th, Friday the 4th, Saturday the 3rd part. But its clock-time shifts a little each day with sunrise and sunset. The practice is to avoid starting new work, undertaking journeys, or signing important agreements during this period.

Yamaganda: Another inauspicious part of the day — Sunday the 5th, Monday the 4th, Tuesday the 3rd, Wednesday the 2nd, Thursday the 1st, Friday the 7th, Saturday the 6th. This too lasts about an hour and a half, and auspicious work is not begun during it.

Abhijit Muhurat: In contrast to the inauspicious periods, Abhijit is a generous auspicious moment. If the day-span is divided into fifteen muhurtas, the 8th muhurta, on either side of noon, is Abhijit — that is, when the Sun stands at mid-sky (on the meridian). By established practice, Abhijit is not taken on Wednesdays.

Bengali Panjika: Barabela, Kalabela and Kalaratri

In the Bengali Panjika, Rahu Kaal or Yamaganda is not central — its place is taken by rules native to Bengal. The Bishuddha Siddhanta Panjika does not print Rahu Kaal; in MyAstrology's Bengali Panjika it is shown at the end as "widely current in the rest of India".

Barabela and Kalabela: The day-span is divided into eight parts; each part is called a "yamardha" (half-prahar). By weekday, particular parts are Barabela and Kalabela — for instance, on Sunday the 4th yamardha of the day-span is Barabela and the 5th yamardha is Kalabela. During these, auspicious work such as marriage, house-entry, or long journeys is avoided.

Kalaratri: Just as the day, the night-span (from sunset to the following sunrise) is divided into eight yamardhas, and by weekday one of them is Kalaratri — on Sunday the 6th yamardha of the night. At night, auspicious work is directed to be avoided during Kalaratri.

"Though Rahu Kaal is widely current throughout India, Bengali society has for ages determined its daily auspicious and inauspicious work by Barabela, Kalabela and Kalaratri."

Bengali Auspicious Yogas: Moment-based Amrit Yog and Mahendra Yog

The basic unit of auspicious time in the Bengali Panjika is the muhurta. Dividing the day-span into fifteen equal parts yields fifteen muhurtas; the night-span is likewise divided into fifteen. Because the length of the day varies with the season, one muhurta in Kolkata is about 43 minutes in winter and about 54 minutes in summer.

Amrit Yog and Mahendra Yog: In the Bishuddha Siddhanta Panjika, these two auspicious yogas fall on particular muhurtas of the day and of the night according to weekday and season. On some days Amrit Yog runs continuously over several muhurtas; on others it is scattered in two or three places. Mahendra Yog falls on one muhurta some days, on more than one on others, and on some days not at all. Thus their duration differs each day. The muhurta tables in our Panjika are built from the daily values of the printed Panjika.

A measured example — Sunday, 11 October 2026, Ranaghat (Nadia): the day's Amrit Yog is from 6:21 to 8:41 AM and from 11:47 AM to 2:52 PM, and Mahendra Yog is from 3:39 to 4:25 PM. On the same day, Barabela is from 9:56 to 11:23 AM.

The Hindi Panchang's "Amrit Kaal" is a completely different thing: it is reckoned by the nakshatra the Moon occupies — from the specified ghati of each nakshatra, four ghatis (of Prashna Marga). Despite the similarity of name, the two times differ. Hence MyAstrology's Hindi and English Panchang show Amrit Kaal, while the Bengali Panjika shows the Bishuddha Siddhanta's Amrit Yog and Mahendra Yog.

"The reckoning of time is not merely a sum of a few numbers; it is the precise expression of the geometry of the Sun, the Earth and the sky, which has been guiding us for thousands of years."
