Schools across Tamil Nadu are scheduled to close for a three-day period from January 15 to January 17, 2026, to observe the Pongal harvest festival and associated events. The holidays include Thai Pongal on January 15, Thiruvalluvar Day and Mattu Pongal on January 16, and Kaanum Pongal/Uzhavar Thirunal on January 17. Some schools may also offer a holiday or shortened hours on January 14, the day before the main festivities begin. The break allows students and staff to participate in the cultural celebrations.
