Pongal is the most famous festival in Tamil Nadu. It is the harvest festival that lasts for four days and is celebrated in the middle of January. The festival is a show of appreciation and gratitude to the Sun God for helping with the agriculture. Preparations for Pongal begin a month before, during the month of Margali when people decorate the entrance of their houses with kolam, coloured rice powder and clean and whitewash their houses thoroughly. During this festival, the first rice of the season is boiled as a tribute to the Sun God.
Each of the four Pongal days are celebrated differently. On the first day which is called Bhogi, is celebrated to honour Lord Indra. The second day is called Thai Pongal when people wear traditional clothes and make various offerings of sugarcane and coconut. The third day is called Mattu Pongal, when cows are decorated with beads, bells and flowers and worshipped. The last day is called Kannum Pongal when families visit each other and exchange gifts. All in all, Pongal is a wonderful festival that brings people together.
