 Celebrated in mid-April every year (usually on 14 or 13 April according to Assamese traditional calendar), the dhol is an important and a quintessential instrument used in Bihu dance.The origin of the Dhol in Assam dates back to at least the 14th century where it was referred in Assamese Buranjis as being played by the indigenous people.This shows that the origin of Dhol in Assam was much older than the rest of India, and the name was probably due to sanskritisation.
