📖 History of the Bangla Calendar
The Bangla Calendar (বাংলা সাল) is believed to have originated during the reign of Mughal Emperor Akbar in the 16th century. The calendar was designed primarily for agricultural and revenue collection purposes. Since Bengal was largely an agrarian society, there was a need for a calendar that aligned with the harvest cycles.
The Bangla Calendar is a solar calendar.
- It is based on the Surya Siddhanta (a Sanskrit astronomical text).
- The calendar was created by reforming the Hindu lunisolar calendar to make it easier for farmers and tax collection.
- Later, during the Bangladesh Liberation War (1971), the calendar became a symbol of cultural identity and is now officially used in Bangladesh alongside the Gregorian calendar.
🗓️ Structure of the Bangla Calendar
The Bangla Calendar is similar to other solar calendars but has its unique features. It is divided into 12 months, each named after a constellation or season. The year usually begins with Pohela Boishakh (পহেলা বৈশাখ), which falls in mid-April.
