Day Two is Thai Pongal, the main event of the festival. As part of the celebration of Pongal in Pondicherry, most of the roads were lined with saree-clad women huddling over pots of steaming milk. When the milk started to overflow, freshly harvested rice grains were added into it. Cardamom, raisins and cashew nuts are also added into the mix sometimes. On the third day, Maatu Pongal, people bathed and decorated their cattle, and fed them a mix of jaggery, banana and other fruits. The fourth and final day is usually spent exchanging gifts or visiting relatives and friends.
Pongal can be quite a busy time for most stays in Pondicherry. While it can be difficult to find good places to stay at, I have a couple of recommendations that might help you out.
