The traditional harvest festival of Pongal is celebrated over how many days?

Pongal is a significant harvest festival celebrated by the Tamil community to express gratitude to the Sun, Mother Nature, and farm animals for their contributions to a successful harvest. The festival spans four distinct days, each with its own significance: Bhogi Pongal (preparation and renewal), Surya Pongal (honoring the Sun god), Maatu Pongal (celebrating cattle), and Kaanum Pongal (family gatherings and outings). Coinciding with the beginning of the Tamil month of Thai, which is considered auspicious, Pongal typically falls on January 14th or 15th annually.
