September 2027 Festival List: Ganesh Chaturthi to Navratri

September 2027 opens with the Ganesh festival and closes on the opening day of Navratri. Hartalika Teej falls on Friday 3 September and Ganesh Chaturthi on Saturday 4 September; ten days after the sthapana comes Anant Chaturdashi on 14 September, and Pitru Paksha begins the next day. The fortnight of ancestor rites runs to Sarva Pitru Amavasya on Thursday 30 September, which is also the date the festival table gives for the start of Sharad Navratri. Around these six festival rows sit two Ekadashis, Parivartini and Indira, two Monday Pradosh evenings and the month’s other tithi fasts, 16 rows in all, listed below with the reading that fixes each.

September 2027 Festival and Vrat Dates (व्रत त्योहार)

The dates are New Delhi readings from the site’s panchang tables, which are generated from NASA JPL’s DE421 ephemeris with the Lahiri ayanamsa. Tithi start and end instants come from the site’s tithi calculator, checked against 86 rows of those tables and never more than 1 minute apart from any of them. Those instants hold everywhere in India; sunrise, sunset and moonrise do not, so a row that sits close to an edge can fall a day differently in a far-off city. The panchang tool gives the reading for your own town.

Bhadrapada Most of the Month, Ashwina at the End

The new moon at 23:11 on 31 August came with the Sun in Leo, so in an amanta almanac, which begins each month at a new moon, Bhadrapada runs through nearly all of September. It ends with the next new moon, at 08:06 on 30 September, by which time the Sun is in Virgo, and amanta Ashwina opens that Thursday morning. A purnimanta almanac, the usual north Indian kind, turns its month at the full moon instead: purnimanta Bhadrapada gives way to Ashwina at 04:33 on 16 September.

The stretch where the two systems disagree is therefore exactly the dark fortnight, the part of Pitru Paksha that follows its Purnima opening. The site’s festival rules file Sarva Pitru Amavasya under amanta Bhadrapada; a purnimanta calendar prints the same fortnight, Indira Ekadashi included, as Ashwina Krishna. The dates do not change, only the month name beside them. Navratri is Ashwina in both, because its Pratipada begins after the new moon. The Sun’s own crossing into Virgo, at 14:04 on 17 September, falls between the full moon and the new moon. It is why the 30 September new moon opens Ashwina, but it changes no month name on its own date; the site gives it as that instant and prints no Sankranti observance day. All of September lies inside Chaturmas, which runs from 14 July to 10 November.

Hartalika Teej and Ganesh Chaturthi, Back to Back

The Shukla Tritiya opens at 16:50 on Thursday 2 September and holds the Friday sunrise, which puts Hartalika Teej on 3 September by the sunrise reading its row uses. At 14:19 that Friday afternoon the Tritiya ends and the Chaturthi begins.

That handover comes after the Friday madhyahna, the third of the five equal parts of daylight, has already closed. Ganesh Chaturthi’s row is fixed by the tithi at madhyahna, so the Friday cannot carry it. On Saturday 4 September the Chaturthi is still running when madhyahna opens, and it ends at 12:26, part-way through that window. That makes 4 September the only day whose madhyahna the tithi reaches, and Ganesh Chaturthi falls there. Because this is the Bhadrapada Chaturthi of the bright fortnight, the table does not add a separate Vinayaka Chaturthi line for the month; the Vinayaka Chaturthi 2027 list treats it the same way. The sthapana window, the overlap of the Chaturthi with that madhyahna, is worked out on the Ganesh Chaturthi page and is not repeated here.

Durgashtami to Anant Chaturdashi

Masik Durgashtami is Wednesday 8 September, and Venus moves into Virgo at 14:36 the next day. Parivartini Ekadashi, which the Ekadashi list also gives as Parsva, follows on Saturday 11 September. Its Shukla Ekadashi runs from 17:00 on 10 September to 19:36 on 11 September and takes one sunrise, so the ordinary rule gives one date. The Vaishnava check, which sets aside an Ekadashi still touched by Dashami at arunodaya (96 minutes before sunrise), does not move it either: the Ekadashi has been running for 687 minutes by then.

The Som Pradosh Vrat on Monday 13 September has a Shukla Trayodashi that fills the whole pradosh window, and the same evening, at 19:33, the Panchak begins; it lasts until 16:47 on 18 September. Anant Chaturdashi is the Tuesday, 14 September. Its Chaturdashi opens at 00:40 in the small hours of that date and ends at 02:48 on 15 September, so the whole of the Tuesday daylight lies inside it. The Ganesh Chaturthi 2027 page places the ten-day immersion on this date.

Pitru Paksha: The Purnima to Sarva Pitru Amavasya

The Chaturdashi’s end at 02:48 on 15 September is the start of the Purnima, and the festival table opens Pitru Paksha on that Wednesday, the one sunrise the Purnima holds. The same day is the month’s Bhadrapada Purnima, kept on a row of its own because the Purnima list counts it. The full moon follows at 04:33 on 16 September, before that day’s sunrise, and the dark fortnight begins there.

The site’s Pitra Dosh notes set each shraddha on the tithi matching the ancestor’s death, and leave the closing Amavasya for a death tithi that is unknown or was missed. That makes a shraddha a question of tithi, which is why this page prints no day-by-day shraddha calendar. The site has no committed rule for the part of the day that fixes a shraddha tithi, and the sunrise column alone would mislead: across the fifteen sunrises from 16 September to 30 September, Krishna Dwitiya holds two and Krishna Shashthi holds none, so the fortnight’s tithis and its civil days do not pair off one to one. A family priest or a local almanac that states its rule is the place to fix a particular shraddha date.

Inside the fortnight the usual monthly fasts carry on. Sankashti Chaturthi is Sunday 19 September, though the Krishna Chaturthi only opens at 07:09 that morning, after sunrise, and it is the Monday sunrise that the tithi holds. The Sankashti reading goes by moonrise rather than sunrise, and New Delhi’s moonrise at 20:03 on the Sunday is the only one inside the tithi. Mercury enters Libra at 18:15 on 21 September, and Kalashtami follows on Thursday 23 September.

Indira Ekadashi on a Ravi Pushya Sunday

Indira Ekadashi, the Ekadashi of the ancestors’ fortnight, is Sunday 26 September. Its Krishna Ekadashi begins at 22:31 the night before and runs to 19:50, so it holds that one sunrise and the Vaishnava arunodaya test leaves it where it is, the tithi being 364 minutes old at arunodaya. The Moon is in Pushya from 14:27 on 25 September to 12:37 on 26 September, and the Sunday sunrise is the one it holds; by the sunrise reading and by the vaar reading alike, that makes Indira Ekadashi a Ravi Pushya day. There is no Guru Pushya this month. The Guru Pushya and Ravi Pushya 2027 page has the year’s list.

Indira is the first of three days in a row. The Som Pradosh Vrat on Monday 27 September is the month’s second Monday Pradosh, and the next day is Masik Shivratri on Tuesday 28 September.

Why Sarva Pitru Amavasya and Navratri Share 30 September

Three rows sit on Thursday 30 September: Sarva Pitru Amavasya, the month’s plain Amavasya row, and the first day of Sharad Navratri. The tithi spans explain it without any adjustment. The Amavasya opens at 10:55 on Wednesday 29 September, too late for that morning’s sunrise, which the Chaturdashi holds. The first sunrise it holds is the Thursday’s, and that is the date a sunrise reading gives it.

The new moon at 08:06 that Thursday ends the Amavasya and opens the Shukla Pratipada, 113 minutes after sunrise. The Pratipada then closes at 05:35 on 1 October, 38 minutes before that day’s sunrise, so it holds no sunrise at all: a kshaya tithi. With no sunrise of its own, the sunrise rule lists it by the day it begins, which is the same 30 September. That is how the last rite of Pitru Paksha and the opening of Navratri come to share a civil date in the table, and the 1 October sunrise already belongs to the Dwitiya. The Navratri 2027 page lists the days that follow, through to Dussehra on 9 October.
