Bohag Bihu, also known as Rongali Bihu or Haat Bihu, is the chief festival celebrated in Assam and North-Eastern states of India, that marks the Assamese New Year. Bihu refers to a set of three festivals and each coincides with a distinctive phase in the farming calendar – Magh Bihu/Bhogali observed in January, Bohag Bihu/Rongali Bihu observed in April and Kaati Bihu/Kongali observed in October. The Rongali Bihu is the most celebrated among the three, as it marks the Assamese New Year and the beginning of the agricultural season. It is the festival of merriment and feasting and is celebrated for seven days. While Bhogali Bihu is all about food and Kongali Bihu is an animistic festival. The word ‘Bihu’ is believed to be originated from the word ‘Bishu’ meaning ‘to ask for peace’. The word transformed to ‘Bihu’ as per the local linguistic preferences. In 2018, Rongali Bihu commences on April 15 and ends on April 21.
