The correct answer is thrice . Key Points Bihu is the most significant cultural and secular festival of Assam , marking the different stages of the agricultural cycle . The festival is celebrated three times in a calendar year, with each iteration occurring at a specific seasonal transition. The first is Rongali Bihu (also known as Bohag Bihu ), celebrated in mid-April to mark the Assamese New Year and the onset of the seeding season. The second is Kati Bihu (or Kongali Bihu ), observed in mid-October, which is a more somber occasion focused on prayer for a good harvest as the paddy grows. The third is Bhogali Bihu (or Magh Bihu ), celebrated in mid-January to mark the end of the harvest season with community feasting and bonfires. Additional Information Rongali Bihu : It is the most popular of the three and lasts for seven days , featuring traditional Bihu dance and songs. It coincides with other spring festivals like Baisakhi , Vishu , and Poila Baisakh . Kati Bihu : Known as Kongali (poor) because granaries are usually empty at this time of year. People light earthen lamps (Saki) under Tulsi plants and in the paddy fields. Bhogali Bihu : Derived from the word Bhoga (eating/enjoyment), it involves building temporary huts called Meji and Bhelaghar . Traditional Assamese sweets like Laru and Pitha are prepared and shared during this time.
