First Onam, Thiruvonam, Third Onam And Fourth Onam 2026: Onam is Kerala’s vibrant harvest festival, celebrated in the Malayalam month of Chingam and closely associated with the legendary homecoming of King
Mahabali. It is known for pookalams, Onasadya, traditional arts, games and community gatherings that express prosperity, equality, gratitude and togetherness.
The main celebrations build toward Thiruvonam, the tenth day of the traditional cycle, while Kerala’s official four-day holiday period begins with First Onam and continues through Fourth Onam.
In 2026, these four days fall from August 25 to 28, with Thiruvonam on August 26. Each day has its own cultural significance.

Onam 2026: When Are First Onam, Thiruvonam, Third Onam and Fourth Onam?
The four official Onam holidays in Kerala in 2026 are:
First Onam — Tuesday, August 25, 2026
Thiruvonam — Wednesday, August 26, 2026
Third Onam — Thursday, August 27, 2026
Fourth Onam — Friday, August 28, 2026

Atham through Thiruvonam forms the core 10-day festival cycle, while First Onam through Fourth Onam refers specifically to the four-day holiday period around the main celebration.

What Is First Onam 2026?
First Onam falls on Tuesday, August 25, 2026, and corresponds to Uthradam, the day immediately before Thiruvonam in the traditional Onam sequence.
Uthradam has a strong sense of anticipation. Traditionally, it is associated with the final preparations to welcome King Mahabali. Homes are cleaned and decorated, provisions for the festive meal are arranged and families make preparations for Thiruvonam.

Kerala Tourism describes Uthradam as the day dedicated to the final preparations for Mahabali’s arrival, with households stocking up on new crops and festive delicacies.
For many families, therefore, First Onam represents preparation, anticipation and the welcoming spirit of Onam.
What Is Thiruvonam 2026?
Thiruvonam falls on Wednesday, August 26, 2026, and is the most important day of the traditional Onam celebrations. It is the second day of Kerala’s four-day official holiday period.
Thiruvonam is traditionally associated with the annual visit of King Mahabali, the legendary ruler whose reign is remembered as a period of prosperity, equality and happiness.
According to the popular Onam legend, Mahabali was sent to the netherworld by Lord Vishnu in his Vamana avatar but was granted permission to visit his people once a year. Onam commemorates that homecoming.

Thiruvonam is marked by some of the festival’s best-known traditions, including elaborate pookalams, the traditional vegetarian Onasadya served on banana leaves, new clothes, family gatherings and cultural celebrations. Kerala Tourism describes Thiruvonam as the pinnacle of Onam festivities.
The day therefore represents the heart of Onam: welcome, abundance, family, community and remembrance of Mahabali.
What Is Third Onam 2026?
Third Onam falls on Thursday, August 27, 2026, the day after Thiruvonam. It is the third day of Kerala’s four-day official Onam holiday.
Third Onam is also associated with Avittam, the nakshatra following Thiruvonam. Unlike Thiruvonam, which has a particularly strong and widely observed ritual identity, the customs associated with the days after Thiruvonam can vary among communities and regions.

The day can be viewed as a continuation of the festive spirit after the main Thiruvonam celebrations. Families may continue visiting relatives, sharing food and participating in local cultural programmes and Onam-related events.
Thus, Third Onam represents the continuation of celebration and togetherness beyond the main festive day, rather than marking a separate major mythological episode.
What Is Fourth Onam 2026?
Fourth Onam falls on Friday, August 28, 2026, and is associated with Chathayam, the day after Avittam. It is the fourth and final day of Kerala’s official four-day Onam holiday.
Fourth Onam brings the four-day holiday period to a close. As with Third Onam, practices can differ from one locality or family to another, and it is best understood as part of the continuation and conclusion of the wider Onam season.
The significance of the day lies in carrying the festive spirit forward while gradually bringing the holiday period to an end.
Why Are There Four Onam Days?
The phrase “four Onam days” can sometimes cause confusion because Onam is also described as a 10-day festival.
The distinction is simple:
Atham to Thiruvonam refers to the traditional 10-day Onam celebration, with Thiruvonam as the culmination. First Onam to Fourth Onam refers to Kerala’s four-day official holiday period surrounding and following Thiruvonam.
The Cultural Meaning Behind the Four Days
Taken together, the four days tell a simple festive story: prepare, welcome, celebrate and continue the spirit of togetherness.
First Onam builds anticipation for the arrival of Mahabali.
Thiruvonam is the central celebration, bringing families and communities together around the pookalam, Onasadya and other traditions.
Third and Fourth Onam extend the festive period and provide time for celebrations to continue after the main day.
At the centre of the festival is the enduring image of Mahabali as a ruler remembered for prosperity and equality. The story, traditions and communal celebrations have helped Onam become a festival celebrated across communities in Kerala and among Malayalis around the world.
Onam 2026: More Than Just One Day
Although Thiruvonam is the central day, Onam is better understood as a season of celebrations rather than a single date. Pookalams grow through the festive period, homes prepare for the traditional feast, cultural performances take place and families come together.
Kerala Tourism describes Onam as a 10-day festival beginning with Atham, while the state’s official holiday calendar separately identifies the four-day First Onam-to-Fourth Onam holiday period.
In 2026, that means the four-day holiday runs from Tuesday, August 25, to Friday, August 28, with Thiruvonam on Wednesday, August 26.
For Malayalis, the significance of these days ultimately goes beyond dates on a calendar. They bring together food, family, folklore, hospitality and the enduring message of prosperity, equality and community associated with Onam.
