Although several festivals are celebrated in Bihar, Chhath or Dala Chhath is a festival which is unique to Bihar. It is dedicated to the Sun God. It is considered to be a means to thank the Sun for bestowing the bounties of life in earth, as also for fulfilling particular wishes.

The word “chhath” denotes the number 6 in Hindi and the festival begins on the sixth day of the Hindu lunar calendar month of “kartik” – it is just after a week of Deepawali. Chhath is the holiest festival for people of Bihar and extends to four days.
