Boun Pimai New Year festival, begins in mid - April and lasts for three days. Held before the onset of the rainy season, it recognizes the importance of water in people’s lives. It’s also a purification festival during which the Buddha images in the household and the temples are ritually cleaned with sacred water.
The Prabang image is moved out of the national museum during the festival to be purified in the ground of Vat Mai.

The most elaborate New Years festival rites in the Lao PDR are held in Luang Prabang with processions of the legendary guardian spirit of town.
