Nalla Neram vs Abhijit muhurat: two ways of finding a good hour

Nalla Neram and Abhijit muhurta are two different answers to the same question: which part of today is good for starting something. Nalla Neram, used mainly in Tamil households, takes the good periods of the Gowri Panchangam, each one-eighth of the day or night, and removes any that clash with Rahu Kaal, Yamagandam or Kuligai. Abhijit muhurta, from the Sanskrit muhurta tradition, is a single window of one-fifteenth of the daylight, centred on local solar noon. They use different divisions of the day, so they overlap only partly.

The site computes both. The Nalla Neram pages show Gowri periods, Nalla Neram and horai for each city; the panchang pages include Abhijit.

How Nalla Neram is computed

The daylight, from local sunrise to local sunset, is split into eight equal parts, and the night into another eight. Each part gets a Gowri name according to the weekday: Amirdha, Uthi, Laabam, Dhanam and Sugam are good; Rogam, Soram and Visham are bad. The full weekday table is in Gowri Panchangam explained.

Nalla Neram is then the good Gowri periods with anything that coincides with Rahu Kaal, Yamagandam or Kuligai taken out. Because all of these are eighths of the same daylight, a clash removes a whole period rather than a slice of one. A typical day ends up with three or four separate daytime windows, plus some at night.

How Abhijit muhurta is computed

The Sanskrit tradition divides the daylight into fifteen muhurtas of equal length. Abhijit is the eighth, the middle one, so it is centred on local solar noon, the moment halfway between sunrise and sunset. It is one of the most widely used general-purpose windows in north and west India, and is often recommended when no other muhurta can be found.

Two points that are frequently got wrong:

• Solar noon is not 12:00 on the clock. It depends on where the city sits within its time zone, and moves by an hour with daylight saving time.
• Abhijit is traditionally not used on Wednesdays.

A worked comparison: Calgary, Saturday 17 October 2026

Sunrise 08:04, sunset 18:37, day length 633 minutes.

Abhijit. One muhurta is 633 ÷ 15 ≈ 42.2 minutes. Solar noon is halfway through the day: 08:04 + 633 ÷ 2 = 08:04 + 316.5 minutes = 13:20.5. Abhijit runs 21.1 minutes either side, 13:00 to 13:42. Note that this is well after 12:00 on the clock, because Calgary sits west of the centre of its time zone and the clocks are still on daylight saving time in October.

Nalla Neram. One Gowri period is 633 ÷ 8 ≈ 79 minutes. Saturday's daytime sequence is Soram, Uthi, Visham, Amirdha, Rogam, Laabam, Dhanam, Sugam. Laabam (14:40–15:59) is removed because it coincides with Yamagandam. The day's Nalla Neram is 09:23–10:43, 12:02–13:21 and 15:59–18:37.

Where they meet. Abhijit's first 21 minutes, 13:00 to 13:21, fall inside Amirdha, the best Gowri period. Its second 21 minutes, 13:21 to 13:42, fall inside Rogam, which Gowri treats as bad. On this day the two systems agree for half of Abhijit and disagree for the other half.

That is not a fault in either calculation. They are separate traditions using different divisions of the day, and nothing obliges a fifteenth and an eighth to line up. Each eighth contains nearly two muhurtas, so how they intersect shifts from day to day as day length changes.

Which one to follow

This is a question of tradition rather than of correctness, and the honest answer is to follow the one your family and your priest use.

• In Tamil Nadu, and among Tamil communities in Singapore, Malaysia, Sri Lanka and elsewhere, Nalla Neram from the Gowri Panchangam is the everyday standard. Weddings and griha pravesam are usually fixed by a fuller muhurta, with Nalla Neram choosing the hour.
• In north and west India, Abhijit, choghadiya and the full panchang are more common, and Gowri is rarely consulted.
• If you want both to agree, look for the overlap. On many days part of Abhijit falls inside a good Gowri period; on others it does not.

Neither system looks at your birth chart, the tithi or the nakshatra. They pick an hour within a day; they do not tell you whether the day itself suits what you are doing. For that, see what muhurta can and cannot tell you.

The city matters more than the system

Whichever you use, compute it for the place where the event happens. The difference between cities is often larger than the difference between systems.

Singapore and Kuala Lumpur sit close to the equator, so the day is close to twelve hours all year and each Gowri period stays near 90 minutes. But both use a time zone well east of their actual longitude, so sunrise comes around seven on the clock and solar noon around one in the afternoon. A Chennai calendar used in Singapore is wrong on every line. Compare Nalla Neram in Singapore, Nalla Neram in Kuala Lumpur and Nalla Neram in Chennai.

Further from the equator, in Toronto, London or Calgary, the eighths and the fifteenths both stretch in summer and shrink in winter, and daylight saving moves everything by an hour twice a year.

Frequently asked questions

Is Abhijit muhurta always at 12 noon?

No. It is centred on local solar noon, the midpoint of sunrise and sunset, which can be well away from 12:00. In Calgary on 17 October 2026 it is 13:00 to 13:42.

Why is there no Abhijit on Wednesday?

The tradition excludes Wednesday. Some almanacs still print the window on Wednesdays with a note, others omit it; either way it is not used that day.

Can Nalla Neram fall at night?

Yes. The night is also split into eight Gowri periods, and the good ones are listed as night Nalla Neram on the city pages.

Which is more auspicious, Nalla Neram or Abhijit?

Neither tradition ranks itself against the other. Use the system your family or priest follows, and compute it for the right city.
