Explanations:The main festival of Assam is Bihu, which is celebrated with great enthusiasm and cultural significance. Bihu is not just a festival but a way of life for the people of Assam, marking the different phases of the agricultural cycle. There are three types of Bihu celebrated in Assam: Rongali Bihu, Kongali Bihu, and Bhogali Bihu.
Rongali Bihu, also known as Bohag Bihu, is celebrated in mid-April and marks the beginning of the Assamese New Year. It is a time of joy and celebration, with traditional dances like the Bihu dance, which is performed by both men and women. The festival is characterized by the exchange of greetings, feasts, and the wearing of traditional Assamese attire.
Kongali Bihu, also known as Kati Bihu, is celebrated in mid-October. It is a more subdued festival compared to Rongali Bihu, as it falls during the lean agricultural season. The focus is on lighting lamps in the fields and around the house to ward off evil spirits and to ensure a good harvest.
Bhogali Bihu, also known as Magh Bihu, is celebrated in mid-January. It is a harvest festival that marks the end of the harvest season. The festival is celebrated with feasts, bonfires, and traditional games. People gather to share food and celebrate the abundance of the harvest.
While other festivals like Pongal and Dussehra are celebrated in other parts of India, they are not the main festivals of Assam. Pongal is a harvest festival celebrated primarily in Tamil Nadu, and Dussehra is a major festival celebrated across India, but it is not the main festival of Assam. Therefore, Bihu is the correct answer as it is the main festival of Assam, deeply rooted in the cultural and agricultural traditions of the region.
