Four Days of Pongal Festival in Tamilnadu 
First Day - Bhogi Pongal
Bhogi is celebrated in honor of Lord Indra who is worshiped for 
bestowing adequate harvest. On  the day of Bhogi, people throw away and 
destroy old clothes and materials and set them on fire. This marks the 
end of the old Thai and the arrival of the new Thai. People draw Kolams 
(floor designs drawn using white paste of newly harvested rice) to 
decorate their houses. Also, fresh harvest of rice, turmeric and 
sugarcane are brought from the field as a preparation for the next day. 
Before cutting the paddy, special puja is performed. The farmers smear 
their ploughs and other tools with sandalwood paste and worship the sun 
and earth.
This is the day when people throw useless household articles into a fire
 made of wood and cow-dung cakes. Dances are performed by girls around 
the bonfire and songs are sung in praise of the gods, the spring and the
 harvest. In 2013, Bhogi Pongal date is on 13th January 2013.  
Second Day – Thai Pongal
Also known as 'Surya Pongal', Thai Pongal day is dedicated to Lord Surya, the Sun God. This 
festival
 marks the first day of the Tamil month of Thai and this is the day on 
which the celebration begins. New rice is collected on the day and 
cooked in pots until they over flow. The pots are decorated with 
flowers, sugarcane pieces and turmeric plants. With the first offering 
made to the Sun, the overflowing of rice is the festive occasion where 
people shout Pongal-o-Pongal!
Sun God is offered boiled milk and jaggery. The image of the Sun God is 
drawn on a board and Kolam designs are drawn around it. Then Puja is 
offered to Sun God to seek his blessings. People prepare a dish called 
venpongal, a combination of rice with dhal and sugar. They also prepare 
with dhal and jaggery (sweet), called Sarkarai pongal. In 2013, Thai Pongal date is on 14th January 2013.  
Third Day - Maatu Pongal or Mattu Pongal
This day is dedicated to cattle and hence called as Maatu Pongal or 
Mattu Pongal. On Maatu Pongal day, prayers are offered to bulls, cows 
and other farm animals which help for agriculture. Farmers clean their 
cattle, paint the horns and cover with shining metal caps. They also tie
 multi-colored beads, tinkling bells, bunch of corn and flower garlands 
around their necks. People 
worship the cattle by bending down, touching their feet and foreheads and Aarati is shown. The cattle are then fed with Pongal. In 2013, Maatu Pongal date is on 15th January 2013.  
Jallikattu
The highlight of Maatu Pongal day is the bull festival called Jallikattu
 or taming the wild bull. Jallikattu is generally seen in villages where
 the young men participate with more enthusiasm. One of the most popular
 events is the one held at Alanganallur, near Madurai. Jallikattu is 
also called as Manju Virattu which means chasing the bull.
Fourth Day - Kaanum Pongal
Kaanum Pongal, also spelled Kanum Pongal, is the final day of Pongal 
celebrations. Kaanum pongal is also known as Thiruvalluvar Day. Kaanum 
means to view and on this day, people meet other family members to enjoy
 the day. Younger members of the family pay homage to the elders and the
 elders thank them by giving money. This day is marked to thank friends 
and relatives for their help in the harvest. Some people take the first 
bit of rice cooked and set it outside for the crows to eat. In 2013, Kaanum Pongal date is on 16th January 2013.
