“The Songkran festival is celebrated in Thailand as the traditional New Year's Day from 13 to 15 April. It coincides with the New Year of many calendars of South and Southeast Asia. The most obvious celebration of Songkran is the throwing of water upon others. Thais roam the streets with containers of water or water guns. In addition, many Thais will have small bowls of beige colored talc sold cheaply and mixed with water which is then smeared on the faces and bodies of random passerbys as a blessing for the new year” – Wikipedia.
