Thiruvalluvar was a celebrated Tamil poet and philosopher who lived in the 4th century BCE. He is best known for authoring Thirukkuṛaḷ, a collection of couplets on ethics, political and economic matters, and love. The text is considered as one of the finest works of Tamil literature.
Thiruvalluvar, was chosen as the Tamil language's greatest historical figure after Tamil scholars unanimously agreed to the proposal. As a result, a resolution to celebrate a day known as "Thiruvalluvar Day" for him by all Tamils was passed on 17 January 1935.
The holiday takes places at the end of the three-day festival for Pongal.
