What is the Indian National Calendar?

The Indian National Calendar, also known as the Saka calendar, is the official civil calendar of the Republic of India. It was adopted on March 22, 1957. The calendar is based on the Saka era, which starts in 78 CE.

What is the Saka era?

The Saka era is an ancient Indian calendar era. Year 1 of the Saka era corresponds to 78 CE in the Gregorian calendar. To convert a Gregorian year to a Saka year, subtract 78 (or 79 before the Gregorian new year in late March).

How many months does the Indian National Calendar have?

The Indian National Calendar has 12 months: Chaitra, Vaisakha, Jyaistha, Asadha, Sravana, Bhadra, Asvina, Kartika, Agrahayana, Pausa, Magha, and Phalguna. Chaitra has 30 days (31 in a leap year), while months 2-6 have 31 days and months 7-12 have 30 days.

When does the Saka new year begin?

The Saka new year (1st of Chaitra) falls on March 22 in a regular year and March 21 in a Gregorian leap year.

Is this the same as the Hindu calendar?

No. The Indian National Calendar is a reformed, standardized civil calendar. Traditional Hindu calendars (Vikram Samvat, regional lunisolar calendars) differ in structure and era. The Saka calendar is a solar calendar used officially by the Indian government.

What years are leap years in the Saka calendar?

A Saka year is a leap year when the corresponding Gregorian year is a leap year. Since Chaitra 1 aligns with March 22/21, you check if the Gregorian year that contains most of that Saka year is a Gregorian leap year.
