Rahu Kaal

Is Rahu Kaal always 90 minutes?

Rahu Kaal is one eighth of daylight, so it runs from under an hour to over two hours. See it stretch with the seasons and move with the weekday.

01 · An eighth of daylight

Rahu Kaal is one eighth of the time from sunrise to sunset, so it stretches and shrinks with the day.

Ninety minutes is an eighth of twelve hours. A longer day gives a longer Rahu Kaal and a shorter day a shorter one. The weekday decides which eighth it is.

02 · The weekday sets the slot

Each weekday has its own eighth.

The order is fixed: the eighth part on Sunday, the second on Monday, the seventh on Tuesday, the fifth on Wednesday, the sixth on Thursday, the fourth on Friday and the third on Saturday.

An eighth of the day, not a fixed length

Rahu Kaal is often described as a 90-minute period. That is the right length only when sunrise and sunset are twelve hours apart. The rule behind it divides the daylight, from local sunrise to local sunset, into eight equal parts, and gives one of them to Rahu Kaal. Yamaganda and Gulika use other parts of the same eight.

So Rahu Kaal is as long as one eighth of that day’s daylight:

Sunday Daylight Rahu Kaal
Delhi, 21 June 2026 13 h 58 min 105 min
Delhi, 20 December 2026 10 h 20 min 77 min
London, 21 June 2026 16 h 38 min 125 min
London, 20 December 2026 7 h 49 min 59 min

Near the equator the parts stay close to 90 minutes all year. Farther from it, and especially in summer and winter, they move well away from it.

The weekday picks the part

Which eighth belongs to Rahu Kaal depends on the vaar: the eighth part on Sunday, the second on Monday, the seventh on Tuesday, the fifth on Wednesday, the sixth on Thursday, the fourth on Friday and the third on Saturday. That is why Rahu Kaal falls late in the afternoon on Sundays and in the morning on Mondays.

Both inputs are local. Two cities on the same day have different sunrises and sunsets, so their Rahu Kaal starts, ends and lasts differently even when the weekday is the same. A Rahu Kaal table printed for one city is not right for another.

What the window is for

In muhurta practice Rahu Kaal is a period in which starting new undertakings is traditionally avoided; it is not a calculation of the node Rahu’s position in the sky, which the Rahu and Ketu explainer covers. The Rahu Kaal guide gives the traditional use and the related windows.
