About this festival

Onam is Kerala's biggest festival, welcoming the legendary King Mahabali, who is believed to visit his people every year. The main day, Thiruvonam, falls on the Thiruvonam (Shravana) star in the month Chingam, at the end of ten days of celebration that begin on Atham.

How it is observed

  • Pookalam: a carpet of flowers laid in front of the home, growing bigger each day from Atham.
  • Onam sadya: a feast of 20+ dishes served on a banana leaf.
  • Vallam kali (snake boat races), Pulikali (tiger dance) and Thiruvathira kali.

Questions people ask

When does Onam start?

Onam celebrations begin ten days earlier on the Atham star; Uthradom (first Onam) is the day before Thiruvonam.

Is Onam on the same date every year?

No. It follows the Thiruvonam star in Chingam, so it falls between late August and mid-September.
