The Saka Calendar is another name for the Indian National Calendar. You may hear it simply referred to as Saka. It is so called because the dates are reckoned from the Saka era of Indian history, which was in BCE 78.
Though the Saka calendar is India’s official civic calendar, the Gregorian calendar is generally used alongside it, particularly for international matters.
Another calendar used in equal importance with the Saka calendar in India is the Vikram Samvat calendar, which is a solar and lunar calendar associated with the Hindu religion.
The Saka calendar was adopted by India’s Government in 1957.
