Tamil New Year, also known as Puthandu, is observed by the Tamil community residing globally, but it is especially significant in the Indian state of Tamil Nadu (TN). It falls on the first day of the Tamil month Chithirai, which typically lies in the middle of April, according to the Gregorian calendar. This day marks the beginning of the Tamil calendar year and is celebrated with grandeur and excitement. The New Year symbolizes the beginning of new and fresh endeavors.

On the day of Tamil New Year, homes are cleaned, and entrances are decorated with 'kolam' designs (floral motif made of rice flour). A feast is prepared, including the specialty dish, 'Mango Pachadi,' which signifies various flavors of life. The reading of 'Panchangam' - the astrological almanac, is also an important tradition on this day. It is believed that this predicts important events for the upcoming year.

Tamil New Year is not just a religious festival, but a social celebration as well, where friends and family come together. Exchanging gifts, visiting temples, and conducting processions featuring folk dances and music are common. Even though it's predominantly celebrated in Tamil Nadu, it's also observed among the Tamil diaspora across the world. Thus, Tamil New Year carries significant cultural, religious, and social import among the Tamil community, marking a fresh beginning.
