The Karam festival, also known as Karma festival, is a harvest festival celebrated in several Indian states, including Jharkhand, West Bengal, Bihar, Madhya Pradesh, Chhattisgarh, Assam, Odisha, and Bangladesh. The festival is dedicated to the worship of Karam-Devta (Karam-Lord/God), the god of power, youth, and youthfulness, and is celebrated for good harvest and health. The festival is held on the 11th day of a full moon (Purnima) of the Hindu month of Bhado, which falls between August and September. During the festival, unmarried girls fast and grow seedlings for 7-9 days. Then, groups of young villagers go to the jungle and collect wood, fruits, and flowers, which are required during the puja (worship) of the Karam God. During this period, people sing and dance together in groups.

The Karam festival is celebrated by diverse groups of people, including Munda, Ho, Oraon, Bagal, Baiga, Binjhwari, Bhumij, Kharia, Kudmi, Karmali, Lohra, Korwa, and many more. The festival is also related to the worship of the Karam tree, which symbolizes fertility, prosperity, and everything that is auspicious. The branch of the Karam tree is carried by the Karma dancers during the festival.

The Karam festival reflects the rich cultural and spiritual heritage of the country. It is a symbol of the deep and unbreakable relationship between nature and humans, and the festival depicts the true protectors of nature. The festival also reflects the unity of human life with nature and the utmost love and respect between brothers and sisters.
