The modern Bengali calendar is introduced by Amir Fatehullah Shirazi. That time it came to be known as Fôsholi Shôn or harvest calendar since it matched with the harvest season of the region. In it, he retained the names of the following Hindu months: 

In 2017, the date of Naba Barsha or Poila Baisakh is April 14. The New Year is popularly referred as Naba Barsa or Nava Varsha in Bengal and Pohela or Poila Baisakh in Bangladesh. It is the first day in the traditional Hindu Bengali Calendar.

The people clean and decorate their houses and make elaborate preparation to welcome the coming Year. They paint patterns on the ground (rangoli) in front of their houses. They usually use flour to make the design on the middle of which they place an earthenware pot, decorated with a red and white swastika considered an auspicious sign. This vessal is filled with holy water and a number of mango leaves to symbolise a prosperous year for the family.

That morning they worship Lakshmi, goddess of wealth. They wear garlands of different types of flowers, like the red orleanders, daisies, roses, hibiscus and marigolds.

The origin of Bengali calendar

  • The Bengali calendar is a solar-sidereal calendar in which the years are known as Bônggabdo. It is based on the calculation of the solar calendar mentioned in Surya Siddhanta.

  • As per the available historical evidence, the Bengali calendar is said to have begun on April 14, 593 of the proleptic Gregorian calendar. The ancient Bengali calendar is believed to have been introduced by King Shoshangko.

  • The calendar was later revised during the time of the third Mughal Emperor Akbar to match with the harvest season. This was done to facilitate the administration with tax collection.

  • During his time his councilor, Fatehullah Shirazi, combined the lunar Hijri and the solar Hindu calendars for better administration.

  • All the months have 31 or 32 days. The twelve months of the calendar are divided into six seasons namely

  • rishsho (summer)
  • Bôrsha (rain
  • Shôrot (early autumn
  • Hemonto (late autumn
  • Šit (winter) and Bôshonto (spring)

  • The names of the months in Bengali calendar were derived from stars or nakshatras mentioned in Hindu astrology: 
    • Baishakh from Bishakha
    • Jiashthya from Jaishtha
    • Ashara from Shar
    • Sraban from Srabani
    • Bhadra from Bhadrapada
    • Ashwin from Aswaini
    • Kartik from Kritika
    • Agrahayon from Agraihon
    • Poush from Poushya
    • Magh from Magha
    • Falgun from Falguni
    • Chaitra from Chitra
    • Boishakh is the first month of the calendar and the Bengali New Year is observed on the first day of the month and so, it is also known as ‘Pohela Boishakh’.
    • Bengalis also call their New Year, ‘noboborsho’, where ‘nobo’ means new and ‘borsho’ stands for year.

    Revision in Bengali calendar

    • The Bengali calendar was revised by the Bangla Academy of Bangladesh, headed by Muhammad Shahidullah, on February 17, 1966 to match with the Gregorian calendar. According to the revision the following recommendations were made for its modernization: 

    • It is decided that the first five months of the calendar will have 31 days each

    • The remaining months from Ashshin to Choitro will be of 30 days

    • The leap year of the Gregorian calendar is adjusted by adding a day to the month of Falgun.

    • This calendar was officially adopted by Bangladesh in 1987. According to the revised form the Bengali New Year is now always observed on 14th April in Bangladesh.

    • The revised calendar however isn’t followed in West Bengal where the old Bengali lunar-solar calendar is still in use and as a result, the New Year day may be observed on different dates in West Bengal and Bangladesh.
