13 Months in a Year

The Ethiopian calendar consists of 13 months, where the first 12 months have 30 days each. The 13th month has five days in a common year and six days in a leap year.

What is a Leap Year?

It is a strictly solar calendar, based on the tropical year. The Ethiopean calendar's historical roots are the same astronomical discoveries which lie behind today's Gregorian Calendar and its predecessor, the Julian Calendar.

Birth Year of Jesus

According to some sources, the Ethiopian Orthodox Tewahido Church indicates that the calendar originally came from Egypt. It is closely related to the Coptic and Julian calendars, but it is not quite the same. The main point of difference lies in the calculation of the date of the birth of Jesus, which means that the Ethiopian calendar is seven to eight years behind the Gregorian calendar.

Revised Julian Calendar

Most other Orthodox churches around the world use the Julian calendar. Others observe the Revised Julian calendar, which is one of the most accurate calendars ever developed.
