Ganga Saptami 2027: Date, Tithi and Ganga Dussehra Gap

Ganga Saptami (गंगा सप्तमी), also called Ganga Jayanti, falls in 2027 on Wednesday 12 May. It is the seventh lunar day of the bright half of Vaishakh, and this year that tithi begins and ends inside the same calendar day, so every city this page tests gives the same answer. It is not Ganga Dussehra, which is a different tithi in the next lunar month: Sunday 13 June, 32 days later.

A Saptami That Fits Inside One Day

The festival table has no row for this observance, so the tithi’s ends come from the site’s tithi code. On every build that code is compared with the opening and closing instants of 86 festival-table rows, and it agrees with each of them to within 1 min. By that working, the Shashthi hands over to the Saptami at 01:24 in the small hours of Wednesday 12 May, and the Saptami gives way to the Ashtami at 23:13 the same night. That is 21 hours 49 min of Saptami, shorter than a full day, and none of it touches 11 or 13 May.

The instants are the same across India. What changes from place to place is where the sun stands against them, and here the margins are wide. At New Delhi the sun rises at 05:32 on 12 May, when the Saptami is already 4 hours 8 min old, and sets at 19:02, 4 hours 11 min before it ends. The whole of that day’s daylight therefore lies within the Saptami.

Two Tests, One Answer

Almanacs do not all date a festival the same way. Some ask which tithi is current at sunrise; others look at the middle of the day. To cover the second kind, this page also reads the tithi at one test instant per day, halfway between sunrise and sunset. That instant is only a test point: it is not a madhyahna window, and it is not offered as a time for any rite, so no clock value is printed for it.

• Tuesday 11 May (New Delhi sunrise 05:33, sunset 19:02): Shukla Shashthi at sunrise; not Saptami at the midday test point
• Wednesday 12 May (New Delhi sunrise 05:32, sunset 19:02): Shukla Saptami at sunrise; Saptami at the midday test point
• Thursday 13 May (New Delhi sunrise 05:31, sunset 19:03): Shukla Ashtami at sunrise; not Saptami at the midday test point

Only 12 May passes either test. This Saptami holds one sunrise, so it is not a skipped tithi, and at under a day long it cannot hold a second, so it is not a doubled one either. No almanac is left choosing between two mornings.

Thirteen Cities on Their Own Sun

The site’s city list has no record for Haridwar, Rishikesh or Prayagraj, so the table uses the cities it does carry along and near the river’s course; Dehradun is the closest of them to Haridwar, and Varanasi sits on the river itself. Each city was tested at its own sunrise and its own midday test point on 11, 12 and 13 May. The last two columns give how long the Saptami had been running at that city’s sunrise, and how long it still had left at sunset.

Every city reads Shashthi on 11 May, Saptami on 12 May and Ashtami on 13 May, at sunrise and at the midday test point alike. The tightest margin at the morning end belongs to Guwahati, the easternmost city on the list, where the sun is up first, at 04:38; even there the Saptami has been running for 3 hours 14 min. At the evening end, Ahmedabad’s sunset at 19:12 is the latest, and it still comes 4 hours 1 min before the close. Both margins dwarf the tithi code’s 1 min disagreement with the tables, so there is no east-west split this year.

Ganga Saptami and Ganga Dussehra Are Different Days

The two names are easy to mix up because both are river festivals of early summer. They sit on different tithis in different months. Ganga Saptami is the Shukla Saptami of Vaishakh. Ganga Dussehra is the Shukla Dashami of Jyeshtha, which the site’s 2027 table dates by the sunrise tithi to Sunday 13 June; its Dashami runs from 02:44 on 13 June to 02:12 on 14 June, and the tithi code matches those ends to within 1 min. Between the two, the Purnima at sunrise on Thursday 20 May closes Vaishakh’s bright half, and the Amavasya at sunrise on Friday 4 June ends the dark fortnight that follows. Counted from 12 May, Ganga Dussehra is 32 days on. Because both fall in a bright half, the month names do not change between the amanta and purnimanta calendars. The Dussehra date has a page of its own: Ganga Dussehra 2027.

The festivals’ own tellings also keep them apart. As the account is told at Ganga Saptami, the river flooded the hermitage of the sage Jahnu on its course, and he drank it up and later let it out again; the river’s name Jahnavi, “daughter of Jahnu”, comes from this episode. In that telling the Saptami marks the release, while the Dashami a month later is kept for the river’s descent to earth.

Four Days After Akshaya Tritiya

Ganga Saptami shares its bright fortnight with Akshaya Tritiya, which the 2027 table puts on Saturday 8 May. That row is dated by the midday rule, not the sunrise rule: the Tritiya opens at 11:43 on 8 May, late that morning, and is also the tithi at the 9 May sunrise. Counted from the table’s date the Saptami is four days on, but only three from the Tritiya sunrise, and the reason is the Panchami. It opens at 06:23 on 10 May, after that morning’s sunrise has gone to the Chaturthi, and closes at 03:48 on 11 May, before the next sunrise. At New Delhi the Panchami therefore holds no sunrise at all, and the daily panchang goes straight from Chaturthi to Shashthi.

How the Day Is Kept

Along the river, at towns such as Haridwar, Rishikesh, Prayagraj and Varanasi, the custom centres on a bath in the Ganga and worship at the ghats. The page describes the custom as its keepers do and makes no claim about what keeping it does for anyone. The order of the puja, and whether a household keeps the day at all, is a matter for the family and its priest.

• Ganga Saptami / Ganga Jayanti: Wednesday 12 May 2027, by sunrise tithi and by the midday test point, in every city tested
• Vaishakh Shukla Saptami (computed): 01:24 to 23:13, both on 12 May

The lunar month is laid out on the Vaishakh month 2027 page, and the month after it on the Jyeshtha month 2027 page; the banyan vrat of that month is on the Vat Savitri 2027 page. The other observances of May are on the May 2027 vrat and tyohar list.
