The Songkran Festival in Thailand, is the Buddhist celebration of the New Year Day. It happen in April 13 to 15 but in some cities is a seven days long holiday.
The original means of throwing the water is a way to respect the people, blessing and wishing good luck to them, but the holiday evolved in a playful water-fighting.
For some days people make a water fighting party everywhere which is the more flashy celebration, however the Songkran Festival has a religious meaning.
