Armenian calendar

This calculator converts a date to an Armenian calendar date and vice versa.

Like the Ancient Egyptian Calendar, the Armenian calendar was a 365 days calendar with 12 months of 30 days and one intercalary period of 5 days. So the date conversion logic is almost the same, except for the epoch of the Armenian calendar. The Armenian calendar epoch (the first day of the calendar) is July 11th, 552 C.E. (Julian calendar)1 or July 13th, 552 proleptic Gregorian calendar. The calculator below converts an Armenian date to a Gregorian date.

The Armenian calendar went out of service in 1923 and was replaced with Gregorian calendar. The reform was introduced by the Soviet Union to all its territories, including Armenia, to simplify administrative procedures and make communication and coordination easier. The Armenian Apostolic Church, however, continued to use the traditional Armenian calendar for liturgical purposes, and it is still in use today.

Although the Armenian calendar is no longer used for civil purposes, it remains an important part of Armenian culture and heritage.
