Rahu Kaal rules: what not to do, what is fine, the exceptions

By The Choghadiya Now Team · Published 16 September 2026

The rule fits in a sentence: do not begin something new during Rahu Kaal. Everything else (what counts as new, what carries on regardless, what to do if you have no choice) follows from that one line, and most of the anxiety around Rahu Kaal comes from forgetting it. It is an avoidance window for beginnings, about ninety minutes a day. It is not a period in which the day stops.

What tradition asks you not to start

The categories the panchang tradition names are beginnings that are meant to carry forward:

A journey: the departure, not the whole trip. Leaving the house for a journey of consequence is the classic example.
A new venture: opening a shop, registering a business, a launch, a first day of trading.
A contract or a large transaction: signing, a first payment, a purchase that is meant to last (a house, gold, a vehicle).
A ceremony or its first step: a puja begun for a purpose, a housewarming, an engagement.
A new job, a new course, a first meeting: anything you would later date from.

What these share is the act of starting. The tradition’s reasoning is that a thing begun in Rahu’s part of the day is begun under an unsupportive influence; the practical reading is simpler: move the start ninety minutes, and nothing is lost.

What is fine during Rahu Kaal

Work already underway. The office does not close, the shop does not shut, a journey already begun does not stop. Rahu Kaal applies to beginnings, not to continuation. This is the most common misunderstanding, and every panchang source says the same thing.
Routine and the unavoidable. Meals, chores, commuting, a medical appointment, an emergency. Nothing in the tradition asks a person to sit still.
Returning. Coming home is not a beginning.
Anything already scheduled by others. A meeting you were called to, an exam, a flight: the beginning was not yours to place.

The line to hold is: is this the start of something I would later count from? If yes, and if you can choose the hour, choose another one. If no, or if you cannot choose, carry on.

Can I travel during Rahu Kaal?

The departure is what tradition cares about. If a journey can start ninety minutes later, most people wait; if it cannot (a train, a flight, someone else’s schedule) it goes, and the tradition has no quarrel with that. Travel already in progress is unaffected. Where people do have discretion, the practice is to step out of the house after the window closes, or before it opens.

Can I start work, or a new task at work?

Yes to the day’s work. The daily routine is continuation, not beginning. What some people hold back for a clear window is the ceremonial or consequential start (the first entry in a new ledger, a launch, a signature), and they hold it for the good choghadiya that follows rather than not doing it at all.

Is it the same everywhere?

The rule is the same; how strictly it is observed is not. Rahu Kaal, or Rahu Kalam in Tamil, Telugu and Kannada usage, is followed most closely in South India, where it is checked before nearly any undertaking. In the north and west it is one line of the panchang among several, and the choghadiya often carries more weight in daily decisions. Neither is wrong; they are different emphases on the same table.

When it is today, and why that changes

Rahu Kaal is one eighth of the real daylight, and which eighth depends on the weekday: the second part on Monday, third on Saturday, fourth on Friday, fifth on Wednesday, sixth on Thursday, seventh on Tuesday, eighth on Sunday. No weekday takes the first part, so roughly the first ninety minutes after sunrise are always free of it.

Because it is an eighth of real daylight, three things follow:

It is longer in summer and shorter in winter. In New Delhi the window is about 105 minutes on 21 June 2026 and 77 minutes on 21 December.
It differs by city on the same day. On Wednesday 16 September 2026 it runs 12:03–1:35 PM in Chennai, 12:15–1:48 PM in New Delhi and 12:34–2:06 PM in Ahmedabad. A printed table for one city is wrong for the next.
It is never at night. Rahu Kaal is defined on daylight only. After sunset there is none; the night’s caution windows belong to the night choghadiya.

There is a shape to the week worth remembering: morning on Monday, Saturday and Friday; midday on Wednesday and Thursday; afternoon on Tuesday; the last light before sunset on Sunday.

The two windows that come with it

Rahu Kaal has two smaller siblings on the same eight-part grid, chosen by their own weekday rules: Yamaganda, traditionally kept clear of health matters and formalities, and Gulika Kaal, the period whose events are said to recur. The three never overlap, and most South Indian panchangs print them together. This site shows all three under the Rahu Kaal answer for the same reason.

When a good choghadiya and Rahu Kaal collide

Both systems divide the same daylight into eight, so each weekday’s Rahu Kaal is exactly one named choghadiya. On five days it lands on a period the choghadiya already marks as avoid. On Tuesday (Shubh) and Thursday (Amrit) it lands on a good one, and there the tradition sides with Rahu Kaal: an auspicious choghadiya that overlaps it is set aside, and the beginning waits for the next clear window. This is the single most useful thing to know if you use both tables.

If you genuinely have no choice

The practice, across sources, is to move the beginning rather than abandon it, and to let go of what cannot be moved. A departure fixed by a timetable, a signing fixed by another party, a task that will not wait: these go ahead. What the tradition offers for those cases varies by region and family, and this site does not prescribe remedies; it describes the timing. The window itself is on the Rahu Kaal page for every city, computed from that city’s own sunrise, with the weekday pattern beneath it.
