The Dwijing Festival organized jointly by Assam tourism department, Assam Tourism Development Corporation (ATDC) and Bodoland Tourism is an annual river fest that takes place in Chirang, Assam from 27th December to 7th January. The festival was initially started by the Bodo community in the year 2016-2017 with the title of “AIE RIVER WINTER FESTIVAL”. The great response and massive footfall of the initial year gave the festival a place in Assam's annual celebration calendar. The festival found a new identity and name "Dwijing Festival" originating from the fact that it occurs on the river bed of "AIE" with "Dwi" meaning "River" and "Zing" meaning "Bank".
The magnanimous river “AIE” meaning “MOTHER” starts from the Himalayan Mountains of Bhutan flowing through the Chirang and Bongaigaon districts of Assam joining river Brahmaputra before falling into its final destination, the Bay of Bengal. The river plays a vital role to near about 30000 families in the Chirang district for their daily livelihoods.
This event is also so popular as it embraces around December and January making it the "New Year Festival" of the state.
