The Assamese Calendar (Assamese: ভাস্কৰাব্দ, lit. ‘Bhāskarābda’) is a luni-solar calendar, followed in the Indian state of Assam. The New Year in the Assamese calendar is known as Bohag Bihu. The calendar year is the same as that of the Bengali calendar. In Assam, the calendar is claimed to be counted from the date of the ascension of Kumar Bhashkar Barman to the throne of Kamrup. It differs 593 years with Gregorian calendar.[1]

Days[edit]
The Assamese Calendar incorporates the seven-day week as used by many other calendars. The names of the days of the week in the Assamese Calendar are based on the Navagraha (Assamese: নৱগ্ৰহ nowogroho). The day begins and ends at sunrise in the Assamese calendar, unlike in the Gregorian calendar, where the day starts at midnight.
