The Bengali Calendar or Bangla Calendar (Bengali: বঙ্গাব্দ, lit. 'Baṅgābda'), colloquially (Bengali: বাংলা সন, romanized: Baṅgla Śon), is a solar calendar[1] used in the Bengal region of the South Asia. A revised version of the calendar is the national and official calendar in Bangladesh and an earlier version of the calendar is followed in the Indian states of West Bengal, Tripura and Assam. Unlike the traditional Indian Hindu calendar which starts with the month of Chaitra, the Bengali calendar starts with Boishakh because of the reforms made during the reign of the Mughal Emperor Akbar in Mughal Bengal. The first day of the Bengali year is known as Pohela Boishakh (Boishakh 1st) which is a public holiday in Bangladesh.[2]
The Bengali era is called Bengali Sambat (BS)[3] or the Bengali year (বাংলা সনBangla Sôn, বাংলা সালBangla sal, or Bangabda)[4] has a zero year that starts in 593/594 CE. It is 594 less than the AD or CE year in the Gregorian calendar if it is before Pôhela Bôishakh, or 593 less if after Pôhela Bôishakh.
