Songkran festival in ChiangMai city.

The Songkran festival (Thai: สงกรานต์, pronounced [sǒŋ.krāːn], is celebrated in Thailand as the traditional New Year's Day from 13 to 15 April. It coincides with the New Year of many calendars of South and Southeast Asia.

The date of the festival was originally set by astrological calculation, but it is now fixed. If these days fall on a weekend, the missed days off are taken on the weekdays immediately following. Songkran falls in the hottest time of the year in Thailand, at the end of the dry season.

           Besides the throwing of water, people celebrating Songkran as a Buddhist festival may also go to a wat (Buddhist monastery) to pray and give food to monks. They may also cleanse Buddha images from household shrines as well as Buddha images at monasteries by gently pouring water mixed with a Thai fragrance (Thai: น้ำอบไทย) over them. It is believed that doing this will bring good luck and prosperity for the New Year. In many cities, such as Chiang Mai, the Buddha images from all of the city's important monasteries are paraded through the streets so that people can toss water at them, ritually 'bathing' the images, as they pass by on ornately decorated floats. In northern Thailand, people may carry handfuls of sand to their neighborhood monastery in order to recompense the dirt that they have carried away on their feet during the rest of the year. The sand is then sculpted into stupa-shaped piles and decorated with colorful flags.
