Puthandu

Puthandu, also known as Puthuvarudam or Tamil New Year, is the first day of year on the Tamil calendar and traditionally celebrated as a festival. The festival date is set with the solar cycle of the lunisolar Hindu calendar, as the first day of the Tamil month Chithirai. It falls on or about 14 April every year on the Gregorian calendar. The same day is observed elsewhere in South and South East Asia as the traditional new year, but is known by other names such as Vishu in Kerala, and Vaisakhi or Baisakhi in central and northern India.
