Gowri Panchangam explained: the weekday table and how to use it

Gowri Panchangam is a Tamil timing system that divides the daytime (sunrise to sunset) into eight equal periods and the night (sunset to the next sunrise) into another eight. Each period carries one of eight names: Amirdha is the best; Uthi, Laabam, Dhanam and Sugam are good; Rogam, Soram and Visham are bad. The order of names depends on the weekday, and the length of each period depends on local sunrise and sunset, so the clock times are different in every city.

The good periods, after removing any that clash with Rahu Kaal, Yamagandam or Kuligai, are what most Tamil households call Nalla Neram, "good time". The site's Nalla Neram pages compute both for your city.

The eight Gowri periods

• Amirdha (nectar) — the best; suitable for any auspicious beginning.
• Uthi (progress) — good; favoured for starting work and new ventures.
• Laabam (gain) — good; favoured for business, trade and money matters.
• Dhanam (wealth) — good; favoured for financial dealings and purchases.
• Sugam (comfort) — good; favoured for household matters and general activity.
• Rogam (illness) — bad; avoided, especially for anything to do with health.
• Soram (loss, theft) — bad; avoided for money and valuables.
• Visham (poison) — bad; avoided for all new beginnings.

These associations are traditional. They describe how the periods are used, not a claim about what will happen.

The daytime weekday table

Each line gives the eight daytime periods in order, from the first eighth after sunrise to the last eighth before sunset.

• Sunday: Uthi, Amirdha, Rogam, Laabam, Dhanam, Sugam, Soram, Visham
• Monday: Amirdha, Visham, Rogam, Laabam, Dhanam, Sugam, Soram, Uthi
• Tuesday: Rogam, Laabam, Dhanam, Sugam, Soram, Uthi, Visham, Amirdha
• Wednesday: Laabam, Dhanam, Sugam, Soram, Visham, Uthi, Amirdha, Rogam
• Thursday: Dhanam, Sugam, Soram, Uthi, Amirdha, Visham, Rogam, Laabam
• Friday: Sugam, Soram, Uthi, Visham, Amirdha, Rogam, Laabam, Dhanam
• Saturday: Soram, Uthi, Visham, Amirdha, Rogam, Laabam, Dhanam, Sugam

The night has its own eight-part sequence for each weekday, running from sunset to the next sunrise. The city pages show both, so there is no need to memorise the night table.

How to compute the times

The arithmetic is the same as for Rahu Kaal.

• Find local sunrise and sunset for the date and city.
• Subtract to get the day length in minutes.
• Divide by eight to get the length of one Gowri period.
• Lay the weekday's sequence over the day, one period at a time from sunrise.

For the night, do the same with the time from sunset to the next morning's sunrise.

Worked example: Calgary, Saturday 17 October 2026

Sunrise is 08:04 and sunset 18:37, a day of 633 minutes. One period is 633 ÷ 8 ≈ 79 minutes. Saturday's sequence gives:

• 08:04–09:23 Soram (bad)
• 09:23–10:43 Uthi (good)
• 10:43–12:02 Visham (bad)
• 12:02–13:21 Amirdha (best)
• 13:21–14:40 Rogam (bad)
• 14:40–15:59 Laabam (good)
• 15:59–17:18 Dhanam (good)
• 17:18–18:37 Sugam (good)

From Gowri to Nalla Neram

Rahu Kaal, Yamagandam and Kuligai are also eighths of the same daylight, so each one lines up exactly with one Gowri period. On the Calgary Saturday:

• Kuligai (Saturday's 1st eighth) is 08:04–09:23, on top of Soram
• Rahu Kaal (Saturday's 3rd eighth) is 10:43–12:02, on top of Visham
• Yamagandam (Saturday's 6th eighth) is 14:40–15:59, on top of Laabam

Laabam is a good Gowri period, but it is cancelled by Yamagandam. What is left is the day's Nalla Neram: 09:23–10:43, 12:02–13:21 and 15:59–18:37.

Two patterns fall out of the table that are worth knowing. First, daytime Rahu Kaal always lands on Visham, on every weekday, so Rahu Kaal never removes a good Gowri period. Second, Yamagandam always does: it sits on Dhanam on Sunday, Tuesday, Wednesday and Thursday, and on Laabam on Monday, Friday and Saturday. Kuligai sits on Soram on most days but on Sugam on Monday. After the clashes are removed, most weekdays keep four good daytime periods and Monday keeps three.

Using the Gowri table sensibly

Gowri Panchangam is a quick, chart-free way to pick an hour within a day. It is used across Tamil Nadu and the Tamil diaspora for starting journeys, opening shops, signing documents and making purchases. Some practical points:

• Use the times for the city where the event takes place. A Chennai calendar is wrong in Singapore or Toronto, because sunrise and day length differ.
• Match the period to the purpose where you can: Laabam or Dhanam for money, Uthi for starting work, Amirdha when in doubt.
• Treat it as one layer. Gowri does not look at tithi, nakshatra or anyone's horoscope. For something significant, such as a wedding or griha pravesam, the day itself is chosen first and Gowri only narrows the hour.

Why printed Gowri charts differ

Printed charts often assume sunrise at 06:00 and a twelve-hour day, giving neat 90-minute blocks: 06:00–07:30, 07:30–09:00 and so on. That is close enough near the equator but drifts badly at higher latitudes and whenever sunrise is far from six. In the Calgary example the first period starts at 08:04 and every period is 79 minutes long, so a fixed chart would be about two hours out at the start of the day and still 37 to 48 minutes out in the last period. Computing from the actual sunrise removes that error.

Frequently asked questions

What is the best Gowri period?

Amirdha is traditionally the best. Uthi, Laabam, Dhanam and Sugam are also good; Rogam, Soram and Visham are avoided.

Is Gowri Panchangam the same as Nalla Neram?

Not quite. Gowri names all sixteen day and night periods. Nalla Neram is the subset of good periods, usually net of Rahu Kaal, Yamagandam and Kuligai.

Is each Gowri period 90 minutes?

Only when the day or night is exactly twelve hours. Each period is one-eighth of the actual day or night, so it is shorter in winter and longer in summer away from the equator.

Does Gowri Panchangam use the same day as the calendar?

The Gowri day starts at local sunrise, not midnight. A period after midnight belongs to the previous date's night sequence.
