The main event, also known as Thai Pongal, takes place on the second of the four days. This day coincides with Makara Sankranthi, a winter harvest festival celebrated throughout India. The day marks the start of the Uttarayanam, the day of the Indic solstice when the sun purportedly enters the 10th house of the Indian zodiac i.e. Makara or Capricorn. In the Tamil language the word Pongal means “overflowing,” signifying abundance and prosperity. During the festival milk is cooked in a vessel. When it starts to bubble and overflows out of the vessel, freshly harvested rice grains are added to the pot. At the same time other participants blow a conch called the sanggu and shout “Pongalo Pongal!” They also recite “Thai Pirandhal Vazhi Pirakkum” (“the commencement of Thai paves the way for new opportunities”). This is repeated frequently during the Pongal festival. The Pongal is then served to everyone in the house along with savories and sweets such as vadai, murukku, paayasam.
