Significance ofย Thiruvonam

King Mahabali was a great and righteous king of South India. The celebration of Thiruvonam is focused on helping people to know his story, reiterate the way that Lord Vishnu tested King Mahabali and was immensely appeased and the return of King Mahabali to his kingdom every year. It is believed that King Mahabali visits his people on the day of Onam, and people decorate their homes, prepare lavish meals and celebrate this day with happiness and fervour to celebrate the life and works of this king.

While the Onam festival traditionally lasts for 10 days, there are some days of Onam which are considered to be more important. The festivities of Onam begin on the day in Chingam where the Atham Nakshatra prevails and go on for ten days. We hope that the celebration of Onam 2025 brings with it the love, light and prosperity that you deserve.
