Onam 2026 Date, Rituals & Onakkodi: Everything to Know Before August 26

If you're reading this today, you're on day five of ten. Onam 2026 began on Atham, 17th August, and it builds day by day until Thiruvonam, the main day, on Wednesday, 26th August. Today is Anizham, the day of the vallam kali boat races, which means there are exactly five days left to get everything, including your Onakkodi, sorted before the festival peaks. Here's the full picture: the dates, what each day actually means, the story behind the festival, and what Onakkodi is really about beyond "buy new clothes."

When Is Onam 2026, Exactly?

The short answer: Thiruvonam, the main day of Onam, falls on Wednesday, 26th August 2026. But Onam isn't a single day, it's a ten-day build-up that starts with Atham and grows in scale and ritual every day until it peaks on Thiruvonam. Most of the visible celebration, the big sadya, the biggest pookalam, and the wearing of new clothes, happens across the final four days, from Uthradam on 25th August through to Fourth Onam on 28th August.

The 10 Days of Onam 2026, Day by Day

Each day of Onam has its own name and its own small ritual, mostly centred around building the pookalam a little larger each morning. Here's how the full calendar lines up this year.

Day	2026 Date	What Happens
Atham	Mon, 17 Aug	The festival opens. Families bathe early, visit the temple, and lay the first, simplest pookalam to welcome King Mahabali.
Chithira	Tue, 18 Aug	The pookalam gets its second layer of flowers and colour; early preparations for the Onasadya begin.
Chodhi	Wed, 19 Aug	The main shopping day for Onakkodi, gifts, and jewellery; markets are at their busiest.
Vishakam	Thu, 20 Aug	Sadya prep intensifies — pickles, pappadam, and other dishes that keep are made in advance.
Anizham	Fri, 21 Aug	Vallam kali, the snake boat races, take place across Kerala's rivers and backwaters.
Thriketa	Sat, 22 Aug	Families travelling home for Onam typically arrive around now; cultural programmes begin.
Moolam	Sun, 23 Aug	Temples start serving Onasadya to devotees; the countdown to Thiruvonam becomes visible everywhere.
Pooradam	Mon, 24 Aug	Clay idols of Onathappan are placed in the pookalam, and homes get their final deep clean.
Uthradam	Tue, 25 Aug	Also called First Onam. Final preparations, Onakazhcha offerings, and the last big cooking push before Thiruvonam.
Thiruvonam	Wed, 26 Aug	The main day: the largest pookalam, new clothes, temple visits, the full Onasadya, and family time.

If you're planning around this, Uthradam and Thiruvonam, 25th and 26th August, are the two days almost everything actually happens on.

The Story Behind the Festival: Mahabali and Vamana

Onam's rituals only really make sense once you know the legend they're built around. Mahabali was a demon king known for being unusually just and generous, so much so that his rule was remembered as a golden age of equality and prosperity. Concerned that Mahabali's growing power was upsetting the cosmic balance, Lord Vishnu took the form of Vamana, a humble dwarf-Brahmin, and approached the king asking for just three paces of land.

Mahabali agreed without hesitation. Vamana then grew to a colossal size and covered the earth in one step and the heavens in a second, leaving no space for a third. Mahabali, understanding what was happening, offered his own head for Vishnu's final step, sending him down to rule the netherworld. Moved by his humility, Vishnu granted Mahabali one wish: to return to his people once a year. Onam marks that homecoming, which is why so much of the festival, the pookalam at the door, the new clothes, the shared feast, is framed as preparing the home to welcome him back.

What Onakkodi Actually Means

Onakkodi is the tradition of wearing, and gifting, new clothes for Onam, but the word carries more history than "shopping" suggests. In Kerala, especially in the southern parts of the state, buying new clothes was historically reserved almost entirely for the Onam season, which arrived right after Karkidakam, the leanest, rainiest month of the year when spending on anything beyond essentials was rare. Onakkodi wasn't just about looking festive; it was the one time families genuinely could afford to.

That's also why gifting Onakkodi became such a meaningful gesture between generations, elders gifting new clothes to children, and in earlier times, landlords gifting them to workers as part of the season's shared prosperity. The Kasavu saree, with its gold zari border, became the signature Onakkodi for women, while men traditionally paired a mundu with a new shirt or kurta. That second half of the tradition, a new shirt worn alongside the mundu, is exactly where a printed onam shirts collection like ours fits into a custom that's been around for generations, not replacing it, just giving it a modern print.

What's Open and What's Closed for Onam 2026

Kerala observes public holidays around the main days of Onam, so if you're planning deliveries, store visits, or travel, it's worth building in a buffer. Kerala's state government has declared public holidays on 25th, 26th, and 28th August 2026, covering Uthradam, Thiruvonam, and Fourth Onam. Many private businesses and markets stay open through the run-up to Thiruvonam itself, since Chodhi and the days around it are when most last-minute Onakkodi shopping actually happens, but expect a genuinely quiet couple of days right around the 25th and 26th.

Getting Your Onakkodi Sorted With Five Days Left

If today's Anizham and you haven't picked out this year's Onakkodi yet, you're not behind, but you are close to the point where popular sizes start running out. Our onam shirts collection has 22 printed Cuban collar designs, each available in regular or oversized fit and half or full sleeve, sized from 22 to 52 so the whole family can be covered from one place. A few of those designs, Thiruvonam, Chingam, Ponnonam, and Keraliyam, are actually named after words from this very festival calendar, so if you'd like your Onakkodi to carry a bit of the story behind it, that's a good place to start looking. If you'd rather narrow down by fit or sleeve length first, we've written separate guides on choosing your fit and half sleeve versus full sleeve for Kerala's weather.
