What Is Onam?

Onam 2026 Date
Onam is mainly celebrated during Thiruvonam (26th August 2026). Thiruvonam is celebrated on this day throughout Kerala (according to Kerala Tourism).

As for every Onam Tourism Week, traditional performances and exhibitions will be organized along with opportunities to experience Kerala culture and social life.
History and Legend of Onam
There's one of the most popular tales that is attached to Onam, which is about the legendary King Mahabali, who was generous and a very good ruler. The legend has it that during the reign of Mahabali, his people were living their lives in a golden age of peace and prosperity.
Vamana, an incarnation of Lord Vishnu, is also a part of this story. According to Hindu tradition, Vamana approached Mahabali in the form of a dwarf Brahmin and requested as much land as he could cover in three steps. Mahabali agreed to the request. Vamana then assumed a cosmic form and covered the earth and heaven in two strides.
There was no place for the 3rd step, so Mahabali gave his head. He was sent away to the underworld, but was allowed to come back to Kerala every year to visit his people. This annually recurrent homecoming of Mahabali is traditionally linked to Onam.
This legend gives Onam its central themes of generosity, prosperity, humility and devotion.
Why Is Onam Celebrated?
Onam is a festival that is celebrated to welcome King Mahabali and to mark the prosperity that his royal ascendancy brought upon them. It's also linked to Kerala's agricultural traditions and harvest season.
The festival provides an opportunity for families and communities to come together, prepare traditional food, decorate their homes and participate in cultural activities. Its festivity is about sharing, hospitality and social harmony.
Major Onam Traditions and Rituals
1. Pookalam
Pookalam is perhaps one of the most famous Onam traditions, where the floor outside the houses is filled with flowers arranged in a vibrant pattern. Fresh flowers are always prettified in an elaborate design, and the latter becomes bigger and more ornate during the celebration, which lasts for 10 days.
Pookalam is a significant visual aspect of Onam and is connected to King Mahabali's celebration.
2. Onam Sadya
One more important point of attraction during the festival is Onam Sadya that is a traditional vegetarian feast. Made up of a collection of dishes placed together, usually on a banana leaf.
Rice curries, curries, vegetables, pickles, chutneys, papad, payasam and regional preparations can be a part of the feast. Thiruvonam is a day on which the family is used to having a very elaborate Sadya.
3. Vallam Kali
Vallam kali or the traditional boat racing is one of the most intriguing Onam-related activities in Kerala. The Kerala rivers and backwaters of Kerala host snake boat races with teams of rowers.
The races involve sports, music, teamwork and involvement of the communities, hence playing an important role in the culture of Kerala.
4. Pulikali
The folk-culture “Pulikali” (tiger-play) is a colourful art that is associated mostly with the city of Thrissur. Performers get their bodies painted in tiger shapes and engage in exciting processions while listening to the traditional music.
