Ali Aye Ligang is one of the most significant festivals of Assam, celebrated with great enthusiasm by the Mising community. This festival marks the beginning of the sowing season and reflects the deep-rooted agricultural traditions of the Mising people. It is observed on the first Wednesday of the Assamese month of Phagun (February–March), a time when farmers start cultivating Ahu rice, a variety of summer paddy.
