Theravada New Year is observed three days after the first full moon appears in April every year and this day will be marked on April 24. This day marks Buddha’s birth, death, enlightenment, and the start of the rainy season. It’s known by many names, such as Songkran in Central Thailand, Pi Mai in Northern Thailand, Choul Chnam Thmey in Cambodia, and Boun Pi Mai in Laos. It’s considered the biggest holiday of the year, equivalent to the western world’s celebration of the New Year.
