The festival that marks the end of the harvest season in India is called Pongal. This multi-day festival is primarily celebrated in the southern state of Tamil Nadu and usually takes place in January. Pongal is named after the traditional dish made from newly harvested rice cooked with milk and jaggery, symbolizing abundance and prosperity. The festival also includes various rituals, including the decoration of homes, worship of household deities, and community gatherings. It serves as a time for families to come together, express gratitude for the harvest, and celebrate the richness of their agrarian culture.
