My favorite Thai Festival is Songkran Day. Songkran Day for me is one of the funniest festivals in Thailand. Songkran Day is the Thai New Years celebration that has roots in using water as a symbol of cleansing for the new year. Of all the feasts and festivals in Thailand, which are many, the Songkran Festival is the most extreme. It begins on the 13th April and ends on the 16th April, It is something like a Public Health Cleaning Day. Water throwing among the people in a spirit of fun and goodwill is the main activity of this festival. Don't for get that do not even thinking to go out to the malls with your good clothes on that days.
