Rishi Panchami 2027 Date: Sunday 5 September

Rishi Panchami (ऋषि पंचमी) is kept on the fifth lunar day of Bhadrapada’s bright half. Read by the tithi that is current at sunrise, Rishi Panchami 2027 falls on Sunday, 5 September 2027, the morning after Ganesh Chaturthi. That is the plain answer to “Rishi Panchami 2027 kab hai”. It is not the only answer an almanac can give, because some almanacs date this observance by the tithi at midday instead, and in 2027 the Panchami sits awkwardly against both middays. The sections below show the clock times, the two readings and how they come out in twelve cities.

When the Panchami Begins and Ends

The opening is printed in the site’s 2027 festival table, on the Ganesh Chaturthi row: the Chaturthi ends, and the Panchami begins, at 12:26 on Saturday 4 September, shortly after noon. The close is not in any table row, so it comes from the site’s tithi code, which recomputes all 86 start and end instants in the festival tables at every build and differs from them by at most 1 min. By that code the Panchami gives way to the Shashthi at 11:18 on Sunday 5 September, late on the second morning. The whole tithi lasts 22 hours 52 min, a little short of a full day, and both of its ends land close to the middle of a day. That one fact is the source of every complication on this page.

The Sunrise Reading: Sunday 5 September

The site’s daily panchang for New Delhi gives Shukla Chaturthi at the sunrise of 4 September, Shukla Panchami at the sunrise of 5 September and Shukla Shashthi at the sunrise of 6 September. Only one dawn, then, falls inside the Panchami, and a calendar that names each day after its sunrise tithi has a single candidate. When the Sun comes up over New Delhi on 5 September, at 06:01, the tithi has already run 17 hours 35 min, and it still has 5 hours 17 min left before the Shashthi takes over.

This reading also explains why the two festivals sit on consecutive days. Ganesh Chaturthi 2027 is dated in the festival table by the Chaturthi at midday, and it lands on Saturday 4 September; the Panchami that follows takes the next sunrise, 5 September. Two days earlier, on Friday 3 September, comes Hartalika Teej, so Teej, Chaturthi and Panchami occupy three days running.

The Midday Test Point Finds No Panchami in Delhi

Almanacs that date Rishi Panchami by midday ask which day has the Panchami current in the middle of daylight. To test that question, this page takes one instant per day, exactly halfway between sunrise and sunset. It is a test point and nothing more: it is not a madhyahna window, not a time for any rite, and its clock value is not printed. A calendar that draws madhyahna as a span for its own place can come out differently from a single point.

At New Delhi the test fails on both days. On 4 September the halfway instant comes 7 min before the Panchami opens, so the Chaturthi is still current. On 5 September the halfway instant comes 1 hour 1 min after the Panchami has closed, so the Shashthi is current. Neither midday holds the tithi. The 4 September miss is narrow, and a few degrees of longitude change it.

Twelve Cities, Two Groups

The Panchami opens and closes at the same instant everywhere in India, but sunrise and sunset do not. Each row below uses that city’s own sunrise and sunset from the solar routine behind the city panchang pages. A cell shows the tithi at sunrise, then the tithi at the midday test point.

Three things hold in every row. The 4 September sunrise is Chaturthi, the 5 September sunrise is Panchami, and the 5 September midday test point is already Shashthi; even at Guwahati, the city furthest east on the list and the one whose second midday comes soonest, the Panchami has ended 3 min before it. So the sunrise reading points to 5 September across the whole list, with the tithi more than sixteen hours old at every dawn.

The 4 September midday column is where the cities divide. Jammu, Pune, Mumbai and Ahmedabad, the four westernmost cities on the list, reach the middle of their day after the Panchami has begun, and so do see the tithi at the test point, Ahmedabad by the widest margin (12 min) and Jammu by the slimmest (3 min). The other eight, New Delhi among them, reach it while the Chaturthi is still running; Guwahati is 1 hour 4 min early. Every one of these margins is wider than twice the tithi code’s 1 min disagreement with the tables, but the narrowest are small enough that an almanac drawing madhyahna as a span, or working from a slightly different sunrise, could read them the other way.

What This Means for Your Calendar

A sunrise-tithi calendar has one date for every city tested: Sunday 5 September. A midday calendar in the four western cities finds the Panchami at its 4 September test point and at no 5 September one, which would favour Saturday 4 September, the same civil day as Ganesh Chaturthi. A midday calendar in New Delhi or further east finds it at neither, and has to fall back on whatever rule it keeps for a tithi that misses both middays. This page does not settle that rule and does not call either day the only possible date. If your family or temple calendar prints 4 September, it is reading midday one way; if it prints 5 September, it is reading midday another way or simply following sunrise. Both are within the range the measured times allow.

The Observance

In the custom as households describe it, Rishi Panchami is a day for honouring the Saptarishi, the seven sages of the tradition, and families that observe it commonly keep a vrat. The details, such as what is eaten or avoided, which images or names are used in the puja, and who in the household keeps the fast, differ from region to region and from family to family; the vrat katha a family reads, and its own priest or almanac, are the places to take them from. In the custom’s own account the day is one of reverence for those sages. This page makes no claim about what keeping the vrat does for the person who keeps it, and it prints no puja window.
