Dussehra 2026: the date, and the one window that decides it

Dussehra — Vijayadashami, the “victory tenth” — falls in 2026 on Tuesday, October 20.

That is the answer, and most readers need nothing more. But it is worth knowing why, because this is one of the handful of festivals each year where the obvious method gives the wrong day, and 2026 is a year in which it does.

Hindu festival dates are tithis: lunar days measured by the angle between the Moon and the Sun, each running roughly 19 to 26 hours and therefore almost never lining up with a midnight-to-midnight date. Because a tithi drifts across the civil day, every festival needs a rule that says which moment of the day decides it. For most, that moment is sunrise — the udaya (उदय, “rising”) rule: whichever tithi is running at dawn owns the day. For Dussehra it is not sunrise. It is aparahna.

Get that one substitution right and October 20 follows. Get it wrong and you will publish the 21st, which is what a sunrise reading of the 2026 window produces. We computed the window with the same panchang engine that powers our live Panchang, and the rest of this guide shows the working before it gets to the day itself.

The computed window: Ashwin Shukla Dashami, 2026

In 2026, Dashami of the bright fortnight of Ashwin begins at 12:50 pm IST on Tuesday, October 20 and ends at 2:12 pm IST on Wednesday, October 21. Navami — the tithi before it — runs from 10:52 am on Monday the 19th until Dashami opens on Tuesday afternoon.

Now look at what that does to sunrise. In Delhi the Sun rises at 6:25 am on October 20, and Dashami will not begin for another six hours and twenty-five minutes. The tithi running at that dawn is Navami. On Wednesday the 21st the Sun rises at 6:26 am and Dashami is running — but it expires at 2:12 that afternoon.

So a plain sunrise rule answers Wednesday the 21st, cleanly and confidently. Every step of that reasoning is correct except the premise, which is that Dussehra is a sunrise festival.

Aparahna (अपराह्ण) is the fourth of the five equal parts into which the classical reckoning divides the daylight from sunrise to sunset — the late afternoon, after midday and before evening. In Delhi on October 20 it runs from 1:13 pm to 3:29 pm. Dashami began at 12:50. It holds that window from end to end, and when the window closes at 3:29 the tithi still has nearly twenty-three hours left to run.

On the 21st, aparahna falls at almost the same clock time — 1:13 pm to 3:29 pm — but Dashami expires inside it, at 2:12. The tithi is present for the first hour of the window and absent for the rest. Both days therefore have some claim under a rule read as overlap, and the tradition settles that the way it usually does: the first qualifying day takes the festival. Read more strictly, as requiring the tithi to prevail through the whole window, only the 20th qualifies at all. Both readings land on the same date, which is the most reassuring thing that can be said about a festival date.

Why aparahna, and the year the two rules disagreed in public

The aparahna rule is not a convenience we adopted to make the arithmetic come out. It is what the day is: the tradition holds that Rama killed Ravana in the late afternoon, and it is the aparahna of Dashami that the observance is anchored to. The same window governs Maha Navami, which is why the two dates move together — and it is why our own festival auditor flags Dussehra as the one festival in its table whose rule needs the first-qualifying-day tie-break spelled out.

The clearest way to see that this matters is a year in which the two rules gave visibly different answers, and 2024 is that year. Navami in 2024 began at 12:07 pm on Friday, October 11 and ended at 10:59 am on Saturday, October 12. At sunrise on the 11th the tithi was still Ashtami; at sunrise on the 12th it was Navami. A sunrise rule therefore says Maha Navami is Saturday the 12th — which would also push Vijayadashami to Sunday the 13th.

That is not what happened. Maha Navami 2024 was kept on Friday, October 11 and Vijayadashami on Saturday, October 12. Compute the aparahna windows and you can see exactly why: on October 11 the aparahna window, 1:16 to 3:35 pm in Delhi, was Navami from end to end, and on October 12 the same window was Dashami from end to end. The observed dates track aparahna precisely, and miss sunrise by a full day in both cases.

2026 has the identical structure. That is the whole argument, and it is worth stating plainly because date listings rarely show any of it: the sunrise rule is the right rule for most festivals and the wrong one for this one, and in a year like this the difference is a day.

A related honesty: the difference between “the tithi overlaps the window” and “the tithi covers the whole window” is a real distinction between traditions, and it decides other festivals in the same season — we worked through it in detail for Bhai Dooj in the Diwali corridor. For Dussehra 2026 it happens not to matter, because both readings give October 20. When a date depends on which reading you take, we say so rather than letting you find out later.

The nine nights around it: Ghatasthapana, Ashtami, Navami, Sandhi Puja

Vijayadashami is the tenth day, so it closes a sequence rather than standing alone. Sharad Navratri 2026 runs October 11 to 19, with Ghatasthapana — the installation of the kalash that opens the nine nights — on Sunday, October 11. Maha Ashtami falls on Sunday, October 18 and Maha Navami on Monday, October 19. Our Navratri guide covers the nine forms of the Goddess, the Ghatasthapana vidhi step by step, and how the vrat is kept; there is also a short calendar entry for the dates in the year around them.

One timing inside that sequence is worth computing here, because it is the shortest and most-missed window of the whole festival. Sandhi Puja — the offering made at the junction (sandhi) of Ashtami and Navami, and the ritual heart of Durga Puja in Bengal, Odisha and Assam — occupies the last 24 minutes of Ashtami and the first 24 minutes of Navami. In 2026 Navami begins at 10:52 am IST on Monday, October 19, so the Sandhi window runs 10:28 am to 11:16 am IST.

Because a tithi is a position of the Moon relative to the Sun and not a local clock event, that window is the same instant everywhere on Earth. It is 10:28 to 11:16 am in Kolkata and in Delhi alike; in London it is 5:58 to 6:46 am on the 19th, and in New York 12:58 to 1:46 am. Sunrise-based timings such as aparahna do shift by city — Kolkata’s aparahna on the 20th runs 12:30 to 2:48 pm against Delhi’s 1:13 to 3:29 pm — but the tithi boundaries themselves do not.

There is one thing our own data does not carry, and it is better said than glossed: we publish no separate date for Durga Visarjan. In practice the immersion follows on Vijayadashami itself in most Bengali observance, but the timing is set locally by the puja committee and the river, not by a rule we can compute, so we do not print one. Ask your local committee, or ask Purohit Ji to work through your own city’s windows with you.

What is actually done on the day

Dussehra is the clearest example in the calendar of one tithi carrying several complete festivals. None of the four observances below is a regional variation on a standard practice; each is the whole day, told through a different victory.

In the North and Centre, the day is the climax of Ramlila. Effigies of Ravana, Kumbhakarna and Meghnad are burned at dusk, closing a cycle of performance that has run through the nine nights. Kullu in Himachal Pradesh inverts the calendar entirely: its Dussehra begins on Vijayadashami and runs for a week afterwards, when everywhere else has finished.

In Bengal, Odisha and Assam the same day is Bijoya Dashami — the Goddess’s farewell. Married women offer sindoor to the idol and to one another before the immersion, and the greeting exchanged afterwards is simply “Bijoya”: the visits and the sweets that follow are as much the festival as the puja was.

In the South the day belongs to Vidyarambham — children are begun on their letters, on the strength of a day named Victory — and to the resumption of the implements that were worshipped the day before. That distinction is worth keeping: in Tamil Nadu, Karnataka and the Telugu country, Ayudha Puja itself is kept on Maha Navami, Monday the 19th, and Vijayadashami is when the tools are ceremonially taken back up (in Kerala this step has its own name, Puja Eduppu). The weapons-worship strand that does belong to the tenth is the North’s Shastra Puja. We work through which rite each region keeps on which of the two days, with both windows computed, in our Ayudha Puja and Vidyarambham 2026 guide. In Maharashtra and the Deccan the observance is Shami puja and seemollanghan, the crossing of the village boundary: apta leaves are exchanged as “gold”, a custom the Mahabharata’s telling connects to the shami tree in which the Pandavas hid their weapons through their year of concealment.

The two stories behind all of this are genuinely two, and they come from different texts. Rama’s victory over Ravana is the Ramayana’s; the Goddess’s victory over the buffalo-demon Mahishasura is told in the Devi Mahatmya, the section of the Markandeya Purana also known as the Durga Saptashati. The much-loved detail that Rama himself invoked Durga in autumn before the battle — the akal bodhan, the “untimely awakening”, since autumn is not her season — belongs to the Bengali Krittivasi retelling of the Ramayana and is not found in Valmiki. It is a real and old tradition; it is simply not the same text, and saying so costs nothing. If you want the battle itself as Valmiki tells it, our encyclopedia has the fall of Ravana, Ravana’s own arc and the theme of ego and downfall that runs through it.

Planning the day, and keeping it away from home

If you are choosing a time on the day itself, the tradition treats Vijayadashami as inherently auspicious — the day’s own name is the reason, and this is the classical day for beginning a venture, a course of study or a new instrument. The window most often named for it is the Vijaya Muhurat, which on the common reckoning is the eleventh of the fifteen muhurtas into which the daylight is divided; on that reckoning it falls in Delhi on October 20 from about 1:58 to 2:44 pm, inside the aparahna. Muhurta conventions vary more than tithi arithmetic does, so take your own city’s window from the live panchang rather than from a table computed for Delhi, and see the muhurat guides if you are timing something specific like a vehicle purchase or a new business.

Abroad, the practical question is usually not the date but the hour. Because the tithi boundaries are absolute instants, Dashami begins at 8:20 am on Tuesday in London and 3:20 am in New York, and ends on Wednesday at 9:42 am and 4:42 am respectively. A UK or North American family keeping the day on Tuesday the 20th is inside the tithi for the whole of their working day; the awkward case is anyone trying to observe on Wednesday evening, which in every Western time zone is already Ekadashi.

A minimum that is genuinely complete, if the day falls midweek and nothing around you is celebrating: light a lamp, put the day’s work-tools in front of it — a laptop counts, and always did in spirit — say why in your own words, and begin one thing you have been putting off. That is Vidyarambham and the resumption in five minutes, and it is closer to the day’s meaning than a longer ritual performed without one. If you want the tools honoured as well, that belongs to the day before — the Ayudha Puja and Vidyarambham guide computes the Navami window it needs.

For the wider year, the Festival Calendar 2026 carries every date with the reasoning behind it, the day’s calendar entry has the observances in brief, and the calendar will place the corridor around your own month. The fortnight immediately before Navratri is Pitru Paksha, covered in our shraddha and tarpan guide; if the Rama half of the day is what draws you, our Sunderkand guide is the natural next reading. Three weeks after Dussehra the Diwali corridor opens, and it carries its own boundary puzzle.

The last word belongs to the tithi. It is a small and slightly pedantic thing to insist that Dussehra 2026 is the 20th and not the 21st — but the reason it is the 20th is that a tradition decided, a long time ago, that this particular victory belongs to the late afternoon. Getting the date right is how you inherit the reason.
