==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.<ref>{{cite book|author=Richard Salomon|title=Indian Epigraphy: A Guide to the Study of Inscriptions in Sanskrit, Prakrit, and the Other Indo-Aryan Languages|url=https://books.google.com/books?id=t-4RDAAAQBAJ |year=1998|publisher=Oxford University Press|isbn=978-0-19-509984-3|pages=148, 246–247, 346}}</ref><ref>{{cite book|author=D.

This calendar was named after king [[Vikramaditya]] with a zero date of 57 BCE.<ref>{{cite book|author=Eleanor Nesbitt|title=Sikhism: a Very Short Introduction |url=https://books.google.com/books?id=XebnCwAAQBAJ&pg=PA122 |year=2016|publisher=Oxford University Press|isbn=978-0-19-874557-0|pages=122, 142}}</ref> 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.<ref name="Klass1978p166">{{cite book|author=[[Morton Klass]]|title=From Field to Factory: Community Structure and Industrialization in West Bengal|url=https://books.google.com/books?id=XAZ2JBQ2vwsC&pg=PA166|year=1978|publisher=University Press of America|isbn=978-0-7618-0420-8|pages=166–167}}</ref><ref name="Nicholas2003p13">{{cite book|author=Ralph W.

==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.<ref name="banglapedia1">{{cite web|url=http://en.banglapedia.org/index.php?title=Bangabda |title=Bangabda - Banglapedia |publisher=En.banglapedia.org |access-date=2017-04-27}}</ref><ref name="Crump2014">{{cite book|author=William D.

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.<ref name= Chakrabarti114/> This was officially adopted by Bangladesh in 1987.<ref name= Chakrabarti114/><ref name=Banglapedia>{{cite book |author=Syed Ashraf Ali|chapter=Bangabda|chapter-url=http://en.banglapedia.org/index.php?title=Bangabda|title=Banglapedia: National Encyclopedia of Bangladesh |editor=Sirajul Islam|editor2=Ahmed A.
