It’s a part of the tradition for the businessmen that they close all their book of accounts and start a new one on the first day of the Bengali calendar. This is believed as a way of renewing and strengthening the business relationships with their customers and business partners.  

The Pohela Boishakh is warmly and joyfully celebrated all over the state and to other countries and states who adopted the Bengali calendar. People celebrate the event with loud festivities and parades to the streets. Over time, the celebration, which had no religious connotation from the start, became an integral part of Bengali culture.  Bangla Nababarsha (Nôbobôrsho) is the first day of the Hindu Bengali calendar which is celebrated by the people of Bangladesh every 14th of April in the Gregorian calendar. New Year’s Day celebration is also known to the Bengali as Pohela Boishakh.  The tradition of the celebration of the first day of the Bengali calendar was introduced the Mughal Emperor when he reformed the calendar so that the collection of taxes would match up with the harvesting period.
