Bangladeshi calendar

The Bangladeshi calendar (Bengali: বাংলা সাল, also called the Bangla Year) is a civil calendar used in Bangladesh, alongside the Gregorian calendar and the Islamic calendar. With roots in the ancient calendars of the region, it is based on Tarikh-e-Ilahi (Divine Era), introduced by the Mughal Emperor Akbar on 10/11 March 1584. Amartya Sen states that only traces of Akbar's influence survive. The calendar is important for Bangladeshi agriculture, as well as festivals and traditional record keeping for revenue and taxation.

Bangladeshi land revenues are still collected by the government in line with this calendar. The calendar's new year day, Pohela Boishakh, is a national holiday.

Origins

The Saka Era was the widely used in Bengal, prior to the arrival of Muslim rule in the region, according to various epigraphical evidence. The Bikrami calendar was in use by the Bengali people of the region. This calendar was named after king Vikramaditya with a zero date of 57 BCE. In rural Bengali communities, the Bengali calendar is credited to "Bikromaditto", like many other parts of India and Nepal. However, unlike these regions where it starts in 57 BCE, the modern Bangladeshi and Bengali calendar starts from 593 CE suggesting that the starting reference year was adjusted at some point.

Akbar's influence

Crop cycle's depended on solar calendars. The Islamic lunar calendar of the Mughal government, before Akbar's era caused problems in tax collection since the lunar year was shorter than the solar year by about eleven days per year. Akbar commissioned his astronomer Fathullah Shirazi to develop a new syncretic calendar to allow land tax and crop tax collection according to the harvest cycles. In 1584, Emperor Akbar commissioned a new calendar as part of tax collection reforms.

Shirazi's new calendar was known as the Tarikh-e-Ilahi (God's Era). It used 1556 as the zero year, the year of Akbar's ascension to the throne. The Tarikh-e-Ilahi calendar were one of the syncretic reforms Akbar introduced, along with a new religion called Din-ilahi, a syncretic faith that integrated Islam and Indian religious ideas. However, Akbar's ideas were almost entirely abandoned after his death, and only traces of the Tarikh-e-Ilahi calendar survive in the modern Bengali calendar, according to Amartya Sen.

Shamsuzzaman Khan believed that Nawab Murshid Quli Khan was responsible for widely implementing the tax collection according to the Bengali calendar throughout Bengal. Khan promoted celebrations of the Punyaha, a ceremonial collection of land taxes. The calendar year became known as the Bangla san in Arabic and Bangla sal in Persian; both terms mean the Bangla Year.

In 1966, a committee headed by Muhammad Shahidullah was appointed in Bangladesh to reform the traditional Bengali calendar. It proposed the first five months 31 days long, rest 30 days each, with the month of Falgun adjusted to 31 days in every leap year. This was officially adopted by Bangladesh in 1987.
