Pongal, a significant harvest festival in South India, particularly Tamil Nadu, will be celebrated from January 13-16, 2026. The four-day festival, linked to nature and agriculture, begins with Bhogi, focusing on renewal and discarding the old, often marked by bonfires. The main day, Thai Pongal, is dedicated to the Sun God. Subsequent days include Mattu Pongal and Kaanum Pongal, highlighting different aspects of life and family bonding. The festival aligns with the Tamil solar calendar and coincides with other regional harvest celebrations.
