Onam 2025: Date, Significance and Traditions
Onam is one of the biggest and most colorful festivals of Kerala. It is a celebration of culture, tradition, and harvest. People across the state eagerly wait for this annual event. In 2025, Onam will be celebrated from August 26 to September 5, with the grand finale on Thiruvonam, September 5.
When is Onam 2025?
Onam is observed in the Malayalam month of Chingam. The festival begins with Atham and ends with Thiruvonam, the most important day. According to the Drik Panchang, Atham falls on August 26, while Thiruvonam is on September 5 in 2025.
This ten-day celebration unites families, communities, and even people living outside Kerala, as many return home to be part of the festivities.
The Legend of King Mahabali
The story of Onam is deeply tied to the legend of King Mahabali. He was a generous and just ruler, loved by his people. Under his reign, Kerala prospered and flourished. However, gods feared his growing power and sought the help of Lord Vishnu.
Vishnu appeared as Vamana, a dwarf Brahmin, and requested three steps of land. With those steps, he claimed the heavens, earth, and finally pushed Mahabali to the underworld. But because of his devotion, Mahabali was granted permission to visit his people once every year. Onam marks this annual return.

Significance of Onam

Onam is not just a harvest festival. It is a symbol of equality, unity, and cultural pride. For Keralites, it is a time to honor their land, traditions, and community bonds. The festival also reflects gratitude for nature’s abundance after the monsoon season.
People believe that King Mahabali visits every home on Thiruvonam, so households prepare to welcome him with joy and respect.
Onam Rituals and Traditions
Onam is packed with vibrant rituals and cultural activities that span ten days. Each day has its own significance and traditions:
- Pookalam: Intricate floral carpets designed at the entrance of homes.
