The story
Pongal is the dish and the act: the pot of new rice boiling in milk until it spills over the rim, and the shout that greets it, Pongalo Pongal! The month of Thai that opens today is the good month; the proverb says Thai piṛandāl vaḻi piṛakkum, when Thai is born a way opens. The rice harvest is in and the farmers thank the Sun, the rain and the cattle in turn.
It is the one Tamil festival that owes nothing to a god's story, and it is kept by Tamils of every religion in Tamil Nadu, Sri Lanka, Malaysia, Singapore and the diaspora, where it is a public holiday in several countries.
