- 📅 Onam 2026 date:
- ⏳ Duration: 10 days
- 🌙 Lunar month: Chingam (Malayalam)
- 🗺️ Celebrated in: Kerala, Tulunadu (Karnataka), Kerala diaspora worldwide
Onam is the most celebrated festival of Kerala, observed over ten magnificent days during the Malayalam month of Chingam (August–September). It commemorates the mythological golden age of King Mahabali, the benevolent asura king who ruled Kerala with absolute justice and equality. According to legend, Lord Vishnu, in his Vamana avatar, pushed Mahabali into the netherworld (Patala) to restore cosmic balance, but granted him the boon to visit his beloved subjects once every year. Onam is that cherished annual reunion, and every Keralite welcomes their beloved king with elaborate preparations, vibrant rituals, and heartfelt devotion.
The festival begins on Atham, nine days before the climactic Thiruvonam day, which falls on the Thiruvonam nakshatra (star) in Chingam. Each of the ten days carries a distinct name and significance: Atham, Chithira, Chodhi, Vishakam, Anizham, Thriketa, Moolam, Pooradam, Uthradom, and the grand Thiruvonam. During this period, households across Kerala transform their courtyards into vibrant canvases with Pookalam — intricate floral rangolis created fresh each morning using dozens of varieties of flowers. The Pookalam grows larger each day, reaching its most elaborate form on Thiruvonam.
The Onam Sadhya, a grand vegetarian feast served on fresh banana leaves, is the culinary heart of the festival. Comprising 26 or more dishes including avial, olan, kalan, erissery, thoran, pachadi, pickles, papadam, payasam, and rice, the Sadhya is both a gastronomic delight and a spiritual offering. Vallam Kali, the famous snake boat race held on the backwaters of Alappuzha and Punnamada Lake, draws thousands of spectators and is one of India's most iconic sporting traditions. Women perform the graceful Thiruvathirakali dance in circles, and Pulikali (tiger dance), Kummattikali (mask dance), and Kathakali performances fill the festive air. Onam transcends religion and caste — it is a celebration of Kerala's shared cultural identity and the enduring spirit of human brotherhood.

Onam 2026 — FAQs
Onam 2026 Thiruvonam (the main day) falls on Wednesday, August 26, 2026. The 10-day festival begins on Atham, August 17, 2026, and concludes on Thiruvonam, August 26, 2026.
Lord Vishnu in his Vamana avatar (dwarf Brahmin form) is the presiding deity of Onam. A clay idol called Thrikkakara Appan is placed at the centre of every Pookalam. Thrikkakara Temple near Ernakulam is the most sacred Onam pilgrimage site.
Onam celebrates King Mahabali's annual return to Kerala. According to legend, Mahabali was a just and benevolent king whose rule was a golden age. Lord Vishnu pushed him to the netherworld but granted him the boon to visit his subjects every year during Onam.
Onam Sadhya is the grand vegetarian feast served on banana leaves on Thiruvonam day. A traditional Sadhya has 26 or more dishes including avial, olan, kalan, erissery, pachadi, thoran, papadam, three types of payasam, pickles, and rice. Everyone eats seated on the floor in a row.
Onam is primarily a celebration of abundance rather than fasting. However, some devotees fast until the Sadhya is served on Thiruvonam. Those visiting the Thrikkakara Appan temple often fast on Thiruvonam morning until puja is completed.
Pookalam is a floral rangoli (carpet) made fresh each morning during the 10 days of Onam. It begins small on Atham and grows larger each day. On Thiruvonam it reaches its most elaborate form. Fresh flowers of many colours — thumba, mukkutti, chethi, kakka, and others — are arranged in concentric circles.
Key Onam activities include: creating Pookalam daily, preparing the grand Sadhya feast, watching Vallam Kali (snake boat races) at Alappuzha, witnessing Pulikali (tiger dance) in Thrissur, attending Kathakali and Thiruvathirakali performances, wearing new Onakkodi clothes, and giving Onam gifts.
