Rahu Kaal computed from your own sunrise and sunset, with Yamaganda, Gulika and Abhijit alongside. We print the weekday rule as well as the answer, because a timing you can work out yourself is one nobody can adjust on you.
Guna Milan reads both Sun charts — the birth-star, the sign and the quarter within it produce the eight tests and your total out of 36. Your own scores are in the free result above; the rule behind each one, and what it means day to day, is in the full report.
Both Sun charts are read and each of the eight tests gets its own score out of 36 — with the rule that produced it printed beside it.
Manglik, Nadi and Bhakoot are checked for both of you — and every classical exception is computed on your own charts, never assumed.
Where a score came out low, you get the fix: what to do, what to avoid, and the dates when your chart support a wedding.
Your own scores are free, above. The rule behind each one, the exceptions, and the dated windows are in the full report.
Rahu Kaal is one eighth of the daylight period, and which eighth depends only on the weekday. That is the entire calculation. Everything else on this page is explanation.
Step one: find sunrise and sunset for your location on the date in question.
Step two: subtract to get the length of daylight, and divide it by eight. Each part comes to roughly ninety minutes - though it stretches in summer and shrinks in winter, and the further from the equator you are, the more it varies.
Step three: a fixed rule assigns one of those eight parts to each weekday. That part is Rahu Kaal.
Here is the rule in full, so you never need this page again:
Nothing else goes into it. No chart, no birth details, no planetary position. Rahu Kaal is identical for everyone in a city on a given day - your neighbour has the same window you do, and so does everyone in the next street.
That last point matters and it is almost never said out loud. Rahu Kaal is not personal. It cannot be, because the calculation contains nothing personal.
If you look at the weekday order - Monday 2nd, Saturday 3rd, Friday 4th, Wednesday 5th, Thursday 6th, Tuesday 7th, Sunday 8th - it seems random. It is not. Write the days in the order Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and assign 8, 2, 7, 5, 6, 4, 3. There is a classical mnemonic for this sequence in most almanacs, and once you have it, you can compute any day in your head given a sunrise and a sunset.
We print the full table on the results page for exactly that reason. A timing you can reproduce yourself is one that nobody can quietly adjust for you.
Two more windows come out of the same eightfold split.
Yamaganda - assigned by its own weekday rule, and read the same way as Rahu Kaal. On Sunday it is the 5th part, Monday the 4th, Tuesday the 3rd, Wednesday the 2nd, Thursday the 1st, Friday the 7th, Saturday the 6th.
Gulika (also called Gulika Kaal or Mandi) - again the same division, again by weekday: Sunday the 7th part, Monday the 6th, Tuesday the 5th, Wednesday the 4th, Thursday the 3rd, Friday the 2nd, Saturday the 1st. Several treatments read Gulika as the milder of the three.
And one window that is not from this division at all:
Abhijit - the eighth of fifteen daylight divisions, which places it around solar noon, running roughly forty-eight minutes. It is the one window the tradition reads as favourable, and it is commonly used as a fallback when no better time can be found. Note that several classical sources exclude Abhijit on Wednesdays - we flag that rather than leaving it out.
People sometimes notice that Rahu Kaal was eighty-four minutes in December and ninety-six in June, and assume something is wrong. Nothing is.
The window is an eighth of the daylight period, and daylight is not a fixed length. In Delhi, daylight runs about ten hours twenty minutes in late December and about fourteen hours in late June. An eighth of the first is seventy-seven minutes; an eighth of the second is one hundred and five. That is a difference of nearly half an hour between the shortest and longest Rahu Kaal of the year, in one city.
Further north the swing is larger; nearer the equator, smaller. Anyone quoting "Rahu Kaal is ninety minutes" is quoting an average.
Sunrise in Kolkata and sunrise in Mumbai differ by well over an hour, because India runs on a single time zone across roughly thirty degrees of longitude. Two cities in the same country, same clock, genuinely different sunrise - and therefore genuinely different Rahu Kaal.
Even within a state it matters. A hundred kilometres east or west shifts sunrise by several minutes, and the whole eightfold division moves with it. A Rahu Kaal copied from a Delhi almanac is not the Rahu Kaal for Chennai, and the gap is not small.
This page computes from the coordinates you give rather than from a nearest-city lookup, which is why the times here may differ by a few minutes from a printed panchang made for a different place.
These windows are arithmetic on sunrise and sunset. They are not events. Nothing occurs in them by itself, no classical source describes harm arriving because of the clock, and the tradition treats them as times to avoid beginning something - a convention about starts.
It is worth following that through. If Rahu Kaal were what it is often described as, then everything begun in that window by anyone anywhere would go badly, every single day, across a whole city at once. That is not a claim any classical text makes, and it is not a claim that survives a moment of thought.
What the convention actually says is narrower and more reasonable: there is a customary window in which people traditionally do not start new undertakings. Whether you keep that custom is your decision. Knowing that it is a custom rather than a hazard is what stops it becoming a source of anxiety - and we would rather hand you that than a warning.
Does work already under way get affected? The convention is about beginnings. Nothing in the sources says an ongoing task is affected, and treating it that way turns ninety minutes a day into a paralysis.
Does it apply to travel? Traditionally journeys are among the things not begun in Rahu Kaal. Many people follow this and many do not.
Is there a night Rahu Kaal? The standard calculation divides daylight only. Some treatments give a night version by dividing sunset to sunrise the same way, and it is much less commonly used.
Does it apply on festivals or auspicious days? Treatments differ. Some hold that a strongly auspicious muhurat overrides it; others avoid the overlap entirely. The sources genuinely disagree, and we print both timings so you can see whether they clash at all.
It will not tell you that something bad will happen. It will not sell you a remedy for a ninety-minute window that arrives every day for everybody in your city. And it will not present an eighth of the daylight period as though it were a personal reading of your chart, because it is not one.
What it gives you is the timing, the rule that produced it, and enough context to decide for yourself what weight to give it.
Your sunrise, your sunset, the length of daylight and each of the eight parts with its start and end time - so the whole calculation is visible rather than compressed into one line.
Which part belongs to which day for Rahu Kaal, Yamaganda and Gulika. Twenty-one entries, printed in full, so any date can be worked out without coming back here.
Daylight runs about ten hours twenty in Delhi in December and about fourteen in June, so an eighth of it swings by nearly half an hour across the year. The ninety-minute figure everyone quotes is an average.
India runs one time zone across thirty degrees of longitude, so sunrise differs by over an hour between the east and west coasts. The whole division moves with it, and a copied almanac time can be badly out.
The eighth of fifteen divisions around solar noon, the one favourable window - with the Wednesday exception flagged and an overlap check against the avoided windows.
A convention about beginnings, applied equally to everyone in a place. Set against the modern presentation of it as a hazard, and what has been added in between.
Coarser than a muhurat, simpler than choghadiya, and using no birth details at all. Knowing which kind of tool it is settles most questions about how much weight to give it.

This rahu kaal calculator by city answers the six questions people search most — rahu kaal timing by day of week, rahu kaal tomorrow, what not to do in rahu kaal, yamaganda and gulika kaal today, rahu kaal kaise nikale — each with the rule behind it. The rahu kaal calculator by city above computes your own result free; the sections below explain what it means, and a rahu kaal calculator by city that shows its working is one you can check against any astrologer.
A rahu kaal calculator by city takes the daylight between your local sunrise and sunset, divides it into eight parts, and picks the part assigned to the weekday: the second on Monday, the seventh on Tuesday, the fifth on Wednesday, the sixth on Thursday, the fourth on Friday, the third on Saturday, the eighth on Sunday. That is why it is roughly 7:30–9:00 on Monday and 4:30–6:00 on Sunday — roughly, because the day length and the sunrise move. This rahu kaal calculator by city uses your coordinates and the date, and prints the exact minutes.
Rahu kaal timing by day of week follows a memorised sequence in every panchang: Sunday 8th part (about 4:30–6:00 pm), Monday 2nd (7:30–9:00 am), Tuesday 7th (3:00–4:30 pm), Wednesday 5th (12:00–1:30 pm), Thursday 6th (1:30–3:00 pm), Friday 4th (10:30–12:00), Saturday 3rd (9:00–10:30 am) — the clock times assuming a 6-to-6 day. Rahu kaal timing by day of week on this page is corrected for your actual sunrise and day length, which shifts these by up to an hour in winter and summer.
Rahu kaal tomorrow is the more useful question, since nobody checks the window after starting. The weekday changes the slot entirely: a Monday morning rahu kaal becomes a Tuesday afternoon one. Rahu kaal tomorrow on this page is printed beside today's, with the day after, and the note when the window overlaps a common start time — a 10 am opening on a Friday, a 9 am journey on a Monday — so the start can be moved by half an hour rather than cancelled.
What not to do in rahu kaal is a shorter list than the fear suggests: do not begin a new venture, a journey, a purchase, a signing, a ceremony or a first meeting. What is fine: continuing work already begun, routine tasks, meals, rest, and anything done for Rahu's own matters — some traditions use the window for Rahu remedies and Durga worship. What not to do in rahu kaal on this page is stated with the texts' logic: the period obstructs beginnings, not living.
Yamaganda and gulika kaal today are the other two inauspicious eighths of the day, each with its own weekday sequence: Yamaganda is the 5th part on Sunday, 4th Monday, 3rd Tuesday, 2nd Wednesday, 1st Thursday, 7th Friday, 6th Saturday; Gulika is the 7th on Sunday, 6th Monday, 5th Tuesday, 4th Wednesday, 3rd Thursday, 2nd Friday, 1st Saturday. The South Indian panchangs weigh Yamaganda heavily. Yamaganda and gulika kaal today are printed on this page beneath rahu kaal, so the day's three windows to avoid are in one table.
Rahu kaal kaise nikale by hand: note the sunrise and sunset, divide the daylight by eight, and count to the weekday's part — second on Monday, seventh on Tuesday, and so on. Rahu kaal kaise nikale for your own city is the form above, which does the arithmetic from your coordinates and prints sunrise, sunset, the part length and the window, plus tomorrow's, Yamaganda and Gulika, so the whole day's avoid-list is one screen.
If you came to this rahu kaal calculator by city to check a result from another app, compare the degree, not just the sign — two tools using different ayanamsas will disagree by about a sign near boundaries. This rahu kaal calculator by city prints Lahiri, the value used, and every intermediate step, so the rahu kaal calculator by city result can be verified line by line.
