Chennai Panchang, 25 April 2027

The five windows in Chennai on 25 April 2027

In clock order through the day. Which numbered eighth of daylight Rahu Kaal, Gulika and Yamaghanta each take is fixed by the weekday rather than by the clock, and no two weekdays share the assignment: on a Sunday Rahu Kaal is the 8th of the eight, Gulika the 7th and Yamaghanta the 5th. Sunrise 05:51 to sunset 18:22 is 12h 31m, so an eighth of it runs 93.9 minutes and a fifteenth — which is what Abhijit is — runs 50 minutes. The Length column is the gap between two endpoints each rounded to the whole minute, which is why the three eighths below read 94 minutes apiece.

The convention the classical almanacs record is that nothing new is begun inside Rahu Kaal, Gulika or Yamaghanta, and that Abhijit and Brahma muhurat are the day’s two settled windows — Brahma muhurat being the ninety-six minutes ending at sunrise, which is why it is the one window here whose length never changes with the season. What the tradition does not do is grade the rest of the day, and neither does this page. Choosing a window for a purpose needs a chart as well as a clock.

What a national panchang gets wrong in Chennai today

The column on the right is the site’s own national table for 25 April 2027, computed for New Delhi from the JPL DE421 ephemeris — the numbers /panchang/2027-04-25/ actually prints. It is the same table almost every panchang in the vertical is a copy of. Every limb on it is right for Chennai; every time on it is wrong, and the last column is by how much.

The widest of them on 25 April 2027 is Sunset, which a national table places 30 minutes later than Chennai's. Longitude explains most of it: Chennai sits 3.06° east of New Delhi, and four minutes per degree is the whole of the local-time correction. The rest is latitude, which does not shift sunrise so much as stretch the day — and because Rahu Kaal is a fraction of that day rather than a span on a clock, a stretched day moves the window further than it moves sunrise. That is why the difference in the table above is not one number repeated seven times.

An eighth of the day is not ninety minutes

Rahu Kaal, Gulika and Yamaghanta are each one eighth of the interval from sunrise to sunset. That is a definition, not an approximation, and it means the length of each is a property of the day rather than a fixed quantity anyone can print once. A table quoting a flat ninety minutes is therefore wrong here today by 4 minutes, and wrong in the short direction — it closes the window early. Across 2027 in Chennai an eighth runs from 85 minutes to 97 minutes, so the error is not a constant either. Abhijit is a fifteenth of the same interval rather than an eighth, so it runs 50 minutes today — a little over half of Rahu Kaal, and it moves with local solar noon rather than with the clock. Brahma muhurat is the exception: fixed at 96 minutes because it is defined as a span before sunrise rather than a fraction of daylight, so in Chennai it shifts with sunrise and never changes length.

Where 25 April sits in Chennai’s year

12h 31m of daylight is the 117th longest of Chennai’s 365 days in 2027. The year’s longest sits 23 minutes above it, on 15 June and 11 other days at the same length; its shortest 70 minutes below, on 19 December and 3 other days at the same length. Against yesterday nothing moved by a whole minute: sunrise, sunset and the length of the day all held. That is what a table printed to the whole minute does with a change measured in seconds — it happens either side of the solstices, where the sun genuinely stalls, and it happens at low latitudes for weeks at a stretch, where the daily change is small all year.

Of the eight cities in this cluster, Chennai is the 3rd to see the sun on 25 April 2027. Sunrise across the eight spans 66 minutes, from 05:08 in Kolkata to 06:14 in Mumbai — and Rahu Kaal’s opening spans 64 minutes, which is the more useful of the two numbers and the one no national table can carry.

The five limbs on 25 April 2027

These five are the same everywhere in India, and they are listed here for completeness rather than because they vary by city — a tithi is an angular relationship between the Sun and the Moon, and an angle does not have a postal address. One caveat is honest and worth stating: the almanac convention is to read each limb at sunrise, and the tabulated values above are read at New Delhi's sunrise. Chennai’s sunrise is 5 minutes later than that, so on a day when a limb turns over inside that gap, the value current at Chennai’s own sunrise is the neighbouring one. The site does not guess which days those are; where a limb is close to its boundary the honest place to look is the neighbouring-day view on the national page for 25 April 2027, which shows the days on either side for exactly this reason.

25 April 2027 in eight cities

East to west, in the order the sun reaches them. The last column is measured from Chennai, so this table is a different table on each of the eight pages that share this date.

The two columns do not run in the same order, and 25 April 2027 is one of the dates where that is visible: Delhi sees the sun before Chennai and still reaches Rahu Kaal 26 minutes after it. The reason is in the fourth column. Both cities take the same numbered eighth on a Sunday, but Chennai’s eighth is 94 minutes against 98 in Delhi, and several eighths of that difference accumulate before the window opens. A shorter day reaches its own afternoon sooner.
