Pongal is also referred to as Thai Pongal (தைப்பொங்கல், also spelled Tai Pongal), is a multi-day Hindu harvest festival celebrated by Tamils in India and Sri Lanka. It is observed at the start of the month Tai according to Tamil solar calendar, and this is typically about January 14. It is dedicated to the Hindu sun god,] the Surya, and corresponds to Makar Sankranti, the harvest festival under many regional names celebrated throughout India. The three days of the Pongal festival are called Bhogi Pongal, Surya Pongal and Maattu Pongal. Some Tamils celebrate a fourth day of Pongal as Kaanum Pongal.
