Chennai Panchang September 2027

In September 2027 the sun rises in Chennai as early as 05:57 on all 11 days from Wednesday 1 September to Saturday 11 September and as late as 05:58 on all 19 days from Sunday 12 September to Thursday 30 September — a spread of 1 minute across the month. Sunset moves from 18:20 on Wednesday 1 September to 17:59 on Thursday 30 September. The longest daylight is 12h 23m on Wednesday 1 September and the shortest 12h 01m on Thursday 30 September.

That matters more than it sounds, because Rahu Kaal, Gulika and Yamaghanta are each one eighth of the interval from sunrise to sunset rather than fixed clock spans — so in Chennai in September 2027 an eighth runs from 90 minutes to 93 minutes, and a table quoting a flat ninety minutes is wrong here by up to 3 minutes. Rahu Kaal on 1 September, a Wednesday, is 12:09-13:41 — the 5th of those eight parts, which is the one a Wednesday always takes.

Because the weekday chooses the part, Rahu Kaal’s position on the clock swings much further than sunrise does. Across September 2027 in Chennai it begins as early as 07:28 on 27 September, a Monday, and as late as 16:45 on 5 September, a Sunday — 9h 16m apart, against a sunrise spread of only 1 minute. There is no single “Rahu Kaal time” to memorise, here or anywhere.

Chennai sits 3.06° east of New Delhi, which on longitude alone would put its sunrise 12 minutes earlier. Measured against the national table it actually runs from 15 minutes earlier to 2 minutes earlier across September 2027. It is a range rather than a constant because latitude bends the figure with the season while longitude only shifts it, and here that bend is worth 13 minutes across the month. The windows drift further than sunrise itself does: on the worst day in the table below the national panchang’s Rahu Kaal begins 19 minutes from Chennai’s, because the same numbered eighth is being taken from a longer or shorter day. A national table would get Chennai’s tithi right and every one of its times wrong.

Tithi, nakshatra, yoga and karana are the same everywhere in India and are read at sunrise from the same DE421 table the rest of the site uses — listed here for completeness, not because they differ by city: across these 30 sunrises the nakshatra takes 27 of its 27 values and the tithi 29 of its 30. In September 2027 Purnima falls on 15 September; Amavasya on 30 September; the two Ekadashis on 11 September and 26 September.
