Onam is the most important and widely celebrated festival of Kerala, marking the annual harvest season and commemorating the legendary return of King Mahabali. Celebrated during the Malayalam month of Chingam (August–September), Onam is a symbol of prosperity, unity, and cultural pride. The festival is famous for its vibrant traditions such as Pookalam (floral rangoli), the grand Onasadya (traditional vegetarian feast served on a banana leaf), Vallam Kali (snake boat races), Pulikali (tiger dance), and classical art forms like Thiruvathira and Kathakali. Homes and public spaces are decorated, people wear traditional attire, and celebrations continue for ten days, culminating on Thiruvonam, the main day of the festival.
