The festival is celebrated as Sangken in northeastern areas of India and as Bizu, Boisuk, Shangrai, and Boisabi in the Chittagong Hill Tracts of Bangladesh, which is the traditional New Year's Day by the indigenous Hindu people and Buddhist community. The Sangken festival is celebrated by the Tai people — Khamti people Khamyang, Phake and Turung people. The festival is also celebrated by Singpho, Tikhak (Tangsa) and Duoniya people. Sangken generally falls in the month of 'Naun Ha', the fifth month of the year of the Tai Lunar calendar coinciding with the month of April. It is celebrated in the last days of the old year and the lunar new year begins on the day just after the end of the festival.
