Assam adds ‘Bhaskarabda’ as Official Assam Calendar


  • On 18th October 2021, the Government of Assam has decided to add ‘Bhaskarabda’ in addition to ‘Saka’ and ‘Gregorian’ that will be used in the official calendar.
  • The local calendar is counted from the date of the ascension of Bhaskaravarman, the 7th-century ruler of Kamrup.
  • Bhaskarabda began when Bhaskaravarman was crowned ruler of the Kamrupa kingdom. He was a contemporary and political ally of northern Indian ruler Harshavardhana.
  • Unlike the Gregorian, where a day starts at midnight, the Assamese calendar begins and ends at sunrise over 24 hours.
  • While the Gregorian goes by the solar cycle, the Saka and Bhaskarabda use a lunisolar system based on both the phases of the moon and the solar year.
  • The gap between Bhaskarabda and Gregorian is 593 years.
