The Nepalis in Assam have preserved and maintained their own traditional social customs. In the process a certain degree of assimilation with the Assamese society has been noted. This is evident from the festivals celebrated, food habits and matrimonial relation where a high degree of assimilation is noted.
There are some ceremonies performed by the Nepalis in Assam in addition to their traditional religious ceremonies. This shows a high level of assimilation into the Assamese fold.
Besides these, the Nepalis of Assam actively participated in the local festival called Bihu. Assam celebrated three Bihus- Magh, Rangali and Kati.
The Magh Bihu celebrated in the month of January/Magh has a Nepali equivalent in Makar Sankranti. The Bohag/Rangali Bihu celebrated in April or Baisakha, is also equally participated by the Nepalis of Assam.
The traditional costume of Nepal is called the Daura Suruwal or Labeda-Suruwal, and consists of a shirt that ends at the knee and fastens at the side with ties, pants, and a kind of shoes called docha. It is worn only by men and can include a coat.
