Onam is Kerala's most celebrated festival, observed over ten days from Atham to Thiruvonam in the Malayalam month of Chingam (August-September). It commemorates the mythical reign of King Mahabali, who is believed to return to Kerala during Onam. Thiruvonam, the main day, falls on the Thiruvonam nakshatra of Chingam. In 2025, Onam falls on September 5. The festival is declared a public holiday across Kerala and is observed by Malayali communities worldwide - from the Middle East to North America and Singapore.
Onam traditions include the elaborately laid Pookalam (flower carpet), the Onasadya (a vegetarian feast served on banana leaf with 26 or more dishes), Vallamkali (snake boat races held in backwaters of Alappuzha and Kottayam), and performances of Thiruvathirakali and Pulikali. The Kerala government promotes Onam as "Kerala Tourism Week," attracting over 2 million tourists annually. The festival has been celebrated for over 1,000 years and finds mention in Sangam literature dating back to the 3rd century AD.
