Puthandu

Puthandu (), also known as Tamil New Year (), is the first day of year on the Tamil calendar that is traditionally celebrated as a festival by Tamils. The festival date is set with the solar cycle of the solar Hindu calendar, as the first day of the month of Chittirai. 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 it is known by other names such as Vishu in Kerala, Bisu Parba in Tulunadu, and Vaisakhi or Baisakhi in central and northern India.

On this day, Tamil people greet each other by saying "Puttāṇṭu vāḻttukaḷ!" () or "Iṉiya puttāṇṭu nalvāḻttukaḷ!" (), which is equivalent to "Happy new year". The day is observed as a family time. Households clean up the house, prepare a tray with fruits, flowers and auspicious items, light up the family puja altar and visit their local temples. People wear new clothes and children go to elders to pay their respects and seek their blessings, then the family sits down to a vegetarian feast.
