Pahela is the first day of Bengali Calendar celebrated on 14 April in Bangladesh and 14/15 April in western part of India. It is new year for people of West Bengal, Tripura, Assam, Jharkhand and Odisha.
The same day is observed elsewhere as the traditional solar new year and a harvest festival by Hindus and Sikhs, and is known by other names such as Vaisakhi in central and north India, Vishu in Kerala, Bohag or Rongali Bihu in Assam.
Bengali greet “Shubho Noboborsho” which is literally “Happy New Year“.
Bengali calender is based on Surya Siddhanta in which the first day of the year concides with the mid-April new year in Mithila, Assam, Burma, Cambodia, Kerala, Manipur, Nepal, Odisha, Sri Lanka, Tamil Nadu and Thailand.
So in Bengal 14 April is Poila Boishakh. According to bengal calander the first five months of the year from Bôishakh to Bhadrô will consist of 31 days each. The remaining seven months of the year from Ashwin to Chôitrô will consist of 30 days each. In every leap year of the Gregorian calendar, an additional day will be added in the month of Falgun (which is 14 days after 29 February).
First day 14 April is the New Year of the Indian solar calendar and all derived calendars including Bengali calendar. So historically this day has been seen as day for a new opening and celebrated accordingly. In Bengal landlords used to allocate sweets among their tenants, and business people commenced a “Halkhata” (new financial records book) and locked their old ones. Vendors used to provoke their consumers to allocate sweets and renew their business relationship with them. There were fairs and festivities all over.
Poyela Boishakh is the day in Bengal when every bengali young or old, rich or poor is in festive mood. Bengali New Year festivities includes fairs and dances and classical jatra plays.
