This four-day festival of thanksgiving to nature takes its name from the Tamil word meaning "to boil" and is held in the month of Thai (Jan-Feb) during the season when rice and other cereals, sugarcane, and turmeric are harvested. The festivities of Pongal usually take off in mid-January and continue for many days ending in mid-February.

The spirit is alive and Pongal is still treated as a time to discard the old and welcome the new. The new crop that is harvested is cooked and offered to the Almighty. Celebrated for four days, the various traditions and customs of this harvest festival are:

The first day of Pongal known as 'Bhogi Pongal' is a day for family gathering and is dedicated to Lord Indra, the king of the deities and God of the Clouds and Rains. Offerings are made to him to please him so that he blesses us for the plentiful harvest. It is also the beginning of the New Year according to the Malayalam calendar and before sunrise, a huge bonfire of useless things in home is lit that is kept burning throughout the night. All the time, boys beat little buffalo-hide drums known as 'Bhogi Kottus'. The houses are then cleaned till they shine and are decorated with Kolams painted using rice four. There are yellow pumpkin flowers are set in cow-dung balls in the middle of these designs. The harvest of rice, turmeric and sugarcane is brought in for next day.

The second day of Pongal known as 'Surya Pongal' is dedicated to the Sun God. The granaries are kept full on this day and Sun God with his rays are painted on a plank as he is worshiped with the birth of the new auspicious month of Thai. Since the word 'Ponga' means 'to boil' representing plentiful and excess yield, a special dish is cooked on this day in a new mud-pot that comes in innovative shapes and have artistic designs on them called 'Pongapani'. The special dish is called 'Sarkkarai Pongal' and is offered to Sun God with sugarcane sticks. It is said that Lord Sundareshwar performed a miracle on this day in the Madurai temple and breathed life into a stone elephant who ate sugarcanes. One can see the depiction of the event in the Meenakshi temple.

The third day known as 'Mattu Pongal' is dedicated to the cattle as cowherds and shepherds pay thanks to their cows and bulls, wah them, paint their horns and cover them with shining metal caps. They are fed 'pongal' and tinkling bells are tied around their neck. Cattle races are conducted and in the game called 'Manji Virattu' groups of young men chase running bulls. Bull fights called 'Jallikattu' are also arranged at some places where young men have to take the money bags tied to the horns of ferocious bulls single-handedly and without the use of arms. Lord Ganesha and Goddess Parvati are also worshipped on this day.

The fourth day is termed as Kaanum Pongal. On this day, people travel to see other family members. On this day, the younger members of the family pay homage to the elders, and the elders thank them by giving token money. Another thing many do is leave food out on banana leaves for birds to take. Many South Indian people will take the first bit of rice cooked in any given day and set it outside for the crows to take, so this is not necessarily a habit only for Pongal.
