"Songkran Festival marks the celebration of the traditional Thai New Year. The first day of the three-day festival, April 13th, is the Maha Songkran Day, or the New Years Day.
People give and receive water blessings during Songkran. After making merit by offering food and new robes to the monks, the Thais would prepare flower garlands, incense, candles, and scented water for the bathing of the Buddha images. This is believed to bring blessing and good luck for the upcoming year. After this ritual, they will bring flowers and scented water to the elderly and the respected to ask for their blessings.
Today the festival is characterized by the fun of water throwing. This practice stems from the belief that the throwing of water will bring rain, and thus abundance and fertility to the land."
