Gowri Panchangam: the day's 8 segments explained step by step

What is Gowri Panchangam?

Gowri Panchangam is a time rhythm. It tells you which parts of the day are suited for important decisions, and which ones you should let pass.

Imagine daylight as a cake, and you cut it into eight equal slices. Each slice gets a name. Four of the names mean "good", that is when you start new work, sign contracts, or have important conversations. The other four mean "bad", that is when you stay quiet.

The system comes from the Tamil panchangam, the classical almanac that has governed everyday planning in Tamil Nadu for centuries. The Gowri table is printed in every panchangam calendar, and millions of people look it up every morning.

The eight names

There are eight names, and they always appear in the same order. The names are cyclic: after the eighth comes the first again. The rhythm is simple, good, bad, good, bad, all the way around.

The weekday determines the starting point

The sequence of the eight names is always the same. The only thing that changes from day to day is which name starts.

Each segment covers exactly one eighth of daylight, from sunrise to sunset. The first segment begins at sunrise. The eighth ends at sunset. Which Gowri fills the first segment depends on the weekday.

This means Monday, Tuesday, Thursday and Friday begin with an auspicious segment. Sunday, Wednesday and Saturday begin with an inauspicious one. But there are always four good windows during the day, they just fall at different times.

Worked example, Thursday 15 January 2026

Let us compute all eight segments for a Thursday in Chennai.

All seven weekdays, the complete table

The table below shows which Gowri names fall in each segment for all seven days. Clock times vary with the season, but the name sequence is always the same.

The season changes the duration

The name sequence never changes. But each segment lasts longer in summer and shorter in winter, because daylight is longer.

In Chennai the difference is moderate: daylight swings between about 650 and 780 minutes over the year. That gives segments of 81–97 minutes. In Copenhagen the swing is far larger: from about 420 minutes in December to over 1,060 minutes in June. That gives segments from 53 to 132 minutes.

That is why you cannot simply memorise clock times from a printed calendar. They apply only to the city and the day the calendar was made for. If you live somewhere else, or look at a different day, you need to compute them from your own sunrise and sunset.

What is Gowri used for in practice?

In Tamil tradition, the Gowri table is the first thing many people look up in the morning. It is used to choose when to start something important: a job offer, a contract, a move, a journey, a property purchase.

• Starting new work? Choose Udayam, Amirtham, Laabham or Shubham.
• Signing something important? Avoid Visham and Rogam.
• Planning a journey? Check that you depart during a good segment.
• Cannot avoid a bad segment? Start a small symbolic action in the preceding good segment, write the first line of an application, for instance, and continue from there.

Gowri Panchangam at night

The system we have described covers the day, from sunrise to sunset. There is an analogous night division: from sunset to the next sunrise, also eight segments, with the same names in a shifted sequence.

In practice most people only use the daytime table, and that is what the printed panchangam calendars show. Our calculator therefore also shows daytime only.
