Rahu Kaal Today — Chennai
Thursday, 2026-08-20 · Chennai, Tamil Nadu · UTC+5:30
Rahu Kaal today
13:46 – 15:20
94 minutes · one-eighth of today's 05:58–18:27 day
Note the length: 94 minutes, not a flat 90. Rahu Kaal is an eighth of the real solar day, so it changes with the season and with where you are. This is computed for Chennai's own coordinates with the Swiss Ephemeris.
The four windows people confuse
Three inauspicious, one auspicious. All four are eighths of today's solar arc in Chennai.
Rahu Kaal
Rahu
13:46 – 15:20
The window to avoid beginning anything new — travel, signing, buying, a first meeting.
Yamaganda
Ketu
05:58 – 07:32
Also avoided for new beginnings, and routinely mistaken for Rahu Kaal.
Gulika Kaal
Saturn
09:05 – 10:39
Saturn's eighth. Traditionally avoided, though held to be the mildest of the three.
Abhijit Muhurat
Brahma
11:48 – 12:38
The opposite: the midday window held to be auspicious for almost anything.

Why Chennai needs its own figure
Across the year
In Chennai, Rahu Kaal is shortest around the December solstice at 85 minutes and longest around the June solstice at 96 minutes — a spread of 11 minutes, driven entirely by this city's latitude. A table printing a flat 90 is wrong at both ends of the year.
Against the nearest city
Tirupati is 110 km away, and today its Rahu Kaal runs 13:50–15:23 against Chennai's 13:46–15:20. Sunrise differs, so the eighth differs. That gap is the reason this page is computed for Chennai rather than for the region.
Frequently asked
What is the Rahu Kaal time today in Chennai?
Today, Thursday, Rahu Kaal in Chennai, Tamil Nadu runs 13:46 to 15:20 — 94 minutes. It is computed from today's sunrise (05:58) and sunset (18:27) for this city, so it is not the same as the figure published for a neighbouring metro.
Is Rahu Kaal always 90 minutes?
No. It is one-eighth of the interval between sunrise and sunset, so it is only 90 minutes when the day is exactly twelve hours long. In Chennai today it is 94 minutes. Tables that print a fixed 1.5 hours for every city and every date are approximating.
Does Rahu Kaal fall at the same time every day?
No — the eighth it occupies is set by the weekday, so it moves substantially. That is also why a table memorised for one day is misleading on the next.
What if I have to start something during Rahu Kaal?
Ongoing work is not affected — the caution is about beginnings. If you can move it, the next auspicious choghadiya in Chennai today is Shubh, 05:58–07:32.
Rahu Kaal in other cities
Rahu Kaal is the same for all of Chennai. Your timing is not.
This window comes from the Sun and the weekday, so the whole city shares it. Whether a period is actually good for you depends on your running dasha and the transits over your own chart.
