Bihu () is an important cultural festival unique to the Indian state of Assam and is of three types – 'Rongali' or 'Bohag Bihu' observed in April, 'Kongali' or 'Kati Bihu' observed in October or November, and 'Bhogali' or 'Magh Bihu' observed in January. The festivals present an admixture of Tibeto-Burman, Austroasiatic and Indo-Aryan traditions entwined so intricately that it is impossible to separate them—festivals which are uniquely Assamese are ones to which all communities of Assam had contributed elements. The Rongali Bihu is the most important of the three, celebrating spring festival.
