泼水节是傣族最隆重的传统节日。它通常在阳历的四月中旬，通常是在清明节10天之前或之后，并持续三到七天。泼水节是傣历新年，也是影响最大，云南省大量少数民族节日中参与人口最多的节日。在这个节日里，傣族人不论男女老少都会打扮好，然后挑着清水到佛寺里。他们会先礼佛，然后开始互相泼水，祝对方好运、幸福、健康。一个人被泼的水越多，他收到的幸运就越多，他就会更快乐。

Water-Splashing Festival is the most ceremonious traditional festival of the Dai minority. It usually takes place in mid-April of the solar calendar, often ten days before or after the Tomb-sweeping Day, and lasts three to seven days. Water-Splashing Festival is the New Year in the Dai calendar, and also a festival with the largest influence and maximum participating population among lots of minority festivals in Yunnan Province. In this festival, the Dai people without reference to age and sex will get dressed up and shoulder clean water to the Buddhist Temple. They will first bathe the Buddha and then begin to splash water with one another for wishing luck, happiness and health. The more water one person is sprinkled, the more luck he receives, and the happier he will be.
