#1. Songkran - Thailand
If you’re in Thailand between April 13th and 15th, get ready for world’s biggest water fight. The celebration marks the beginning of the Thai New Year, where cleansing with water is meant to purify and renew. In Bangkok or Chang Mai, the water fights can last up to six days, as Thais and tourists ambush each other in the streets with hoses and water balloons. While this is the most popular activity, Songkran is also a time when people visit elders and monks to pay their respects to the New Year.
