Thailand hosts their New Year on the 13th of April, which is in accordance with the Buddhist & Hindu solar calendar. The dates, 14th and 15th, are also declared a holiday; all of which encourage days of celebration. The younger crowd regularly hosts water festivals on these days. The main roads are closed off to vehicles and used as battlegrounds for the water fights. Splashing water on everyone is the most enthusiastic way that Thai people celebrate New Year and should you be in the country in April, this is a must to see.
