Their traditional new year begins in mid April when they celebrate the occasion with much pomp and gaiety. Like their non Bodo counterparts, they begin the festival with cow worship. The annual spring is allowed to continue for a week. Cow worship is followed by the Bathow pujas the next day whom the other Hindus call the Lord Shiva.
