The festival at the Dau pagoda in Northern Vietnam takes place in the fourth lunar month (the first three months of the lunar year are the busiest for festivals.) The Dau Pagoda Festival, held on the eighth day of the fourth lunar month at the Dau Pagoda (Thuan Thanh, Ha Bac province), commemorates the goddess Man Nuong and is dedicated to the Cloud, Lightning, Rain and Thunder Spirits. This is also the birth date of Buddha, further adding significance to this festival.
