History

Before the introduction of the Bengali calendar in medieval times, agricultural and land taxes were collected according to the Islamic Hijri calendar. However, as the Hijri Calendar is a lunar calendar, the agricultural year did not always coincide with the fiscal year. Therefore, farmers were hard-pressed to pay taxes out of season. In order to streamline tax collection, the Mughal Emperor Akbar, who ruled from 1556 AD until 1605 AD, ordered a reform of the calendar. Accordingly, Amir Fatehullah Shirazi, a renowned scholar of the time and the royal astronomer, formulated a new calendar based on the lunar Hijri and solar Hindu calendars. The resulting Bangla calendar was introduced following the harvesting season when the peasantry would be in a relatively sound financial position. In keeping with the harvesting season, this new calendar initially came to be known as the Harvest Calendar, or ফসলী সন Fôsholi Shôn. For people named Islam, see Islam (name). ...

In a different interpretation, King Shashanka of Ancient Bengal, who ruled approximately between 600 AD and 625 AD, is credited with starting the Bengali era^{[citation needed]}. Shashankya was the sovereign king of Bengal at the start of seventh century. Much of today’s Indian states of Bengal, Bihar, and Orissa was under his kingdom. The prevailing reason is that the year cannot start as 963 B.S. (Bangla Shôn) in synchrony with 963 Hijra. The Bengali Era must have begun before that and Akbar took over form this point on. According to this the starting point of Bengali Era was AD 593/594. By the time of reign of Akbar in AD 1556 the Bengali Era 963 B.S. had been in synchrony with then used 963 Hijra era. Because of the practical advantages of using a solar year, Akbar started using the Bengali era as the official calendar for collecting taxes. Extrapolating further back to the starting point of Bengali era it could be stated that it started on Monday, 12 April 594 in Julian Calendar and Monday, 14 April 594 in proleptic Gregorian calendar. Shashanka (Bangla: শশাঙ্ক) is often attributed with creating the first unified political entity in Bengal. ...

Revised Bengali Calendar

The Bengali Calendar was modified by a committee headed by the celebrated scholar Dr. Muhammad Shahidullah under the auspices of the Bangla Academy on 17 February 1966. The Committee made some recommendations regarding the different problems facing rural Bengali cultural traditions due to changes of months and seasons. Muhammad Shahidullah, popularly known as Dr. Shahidullah (born July 10, 1885 — died July 3, 1969) was a famous Bengali educationist, writer and linguist. ...

Year 1966 (MCMLXVI) was a common year starting on Saturday (link will display full calendar) of the 1966 Gregorian calendar. ...

The length of a year in the Bengali calendar, as in the Gregorian calendar, is counted as 365 days. However, the actual time taken by the earth in its revolution around the sun is 365 days 5 hours 48 minutes and 47 seconds. To make up this discrepancy, the Gregorian calendar adds an extra day, to make a leap year, to the month of February every fourth year (except in century years which are not divisible by 400). The Bengali calendar, which was based on astronomical calculations, did not make this extra leap year adjustment. Bengali months, too, were of different lengths. To counter this discrepancy, and to make the Bengali calendar more precise, the following recommendations of the Bangla Academy are followed: For the calendar of religious holidays and periods, see liturgical year. ... For other uses, see February (disambiguation). ...

• The first five months of the year from Boishakh to Bhadro will consist of 31 days each.
• The remaining seven months of the year from Ashshin to Choitro will consist of 30 days each.

The revised calendar is officially adopted in Bangladesh. However, it is not followed in the neighbouring state of West Bengal, India, where the old calendar continues to be followed. , West Bengal (Bengali: পশ্চিমবঙ্গ Poshchimbôŋgo) is a state in eastern India. ...

Revised and non-revised versions

The first of Boishakh, Pôhela Boishakh, is the Bengali New Year's Day. In Bangladesh, it is celebrated on April 14 every year according to the reformed calendar prepared by the Bangla Academy. However, since the people of the West Bengal follow the non-reformed calendar, which is not fixed with respect to the Western calendar, Indian Bengalis celebrate New Year's Day on April 15.

In West Bengal, India, the Bengalis follow a sidereal solar calendar unlike the tropical solar calendars, such as the reformed Bengali and Gregorian Calendars. The mathematical difference between the sidereal and the tropical calendars amounts to the difference of starting the new year in Bangladesh and West Bengal, India. Because of this the length of the months are also not fixed in the Bengali sidereal calendar, but rather are based on the true movement of the sun. The orbital period is the time it takes a planet (or another object) to make one full orbit. ...

Leap year

According to the new calendar system, Falgun (which begins mid-February) has 31 days every four years. To keep pace with the Gregorian calendar, the Bengali leap years are those whose corresponding Gregorian calendar year is counted as a leap year. For example, Falgun 1410 was considered a Bengali leap month, as it fell during the Gregorian leap month of February 2004. For the 1921 film starring Fatty Arbuckle, see Leap Year (film). ...

Although the sidereal solar calendar is being followed in West Bengal, India, the number of days in the months are determined by the true motion of the Sun through zodiac. In this calendar, seven is subtracted from the year number the result is divided by 39. If after the division the remainder becomes zero or could be divided by 4, the year is then designated as a leap year and contains 366 days with the last month Choitro taking 31 days. There are 10 leap years in every 37 years, although an extraordinary revision may be required over a long time.

Usage

The usage and popularity of the Bengali calendar in eastern South Asia is partly due to its adaptation to the unique seasonal patterns of the region.

In everyday use, the Bengali Calendar has been largely replaced by the Gregorian Calendar in Bengali-speaking regions, although it is still essential for marking holidays specific to Bengali culture (e.g. Pôhela Boishakh, Durga Puja, etc.), and for marking the seasons of the year, and is thus recognized by the Bangladeshi government for the observation of public holidays. Almost every Bengali- and English-language newspaper in Bangladesh and West Bengal prints the day's date according to the Bengali Calendar alongside the corresponding date of the Gregorian Calendar. Many newspapers in Bangladesh also add a third date, following the Islamic Hijri Calendar. Thus, it is quite common in Bangladesh to find the date written three times (e.g. "25 Falgun 1412, 17 Muharram 1427, 27 February 2006") under the newspaper title.
