Thai Poosam is a festival of Murugan held in the Tamil month of Thai, on the day of the Poosam (Pushya) star around the full moon.¹

Many devotees fast beforehand and carry kavadis, decorated arches that sometimes hold pots of milk, to Murugan temples.^1,2

Tamil Nadu Tourism describes it as the most important festival of the Dhandayuthapani Swamy temple at Palani.²
