Enkutatash or Ethiopian New Year is celebrated on September 11th. Ethiopiafollows the Orthodox Julian calendar which consists of 12 months of 30 days and a 13th month, Pagume, of five or six days, depending on whether or not it is a leap year.
There is a seven years and eight months difference between the Ethiopian and the Gregorian calendar, so 11 September 2013 is 1 Meskerem 2006 in Ethiopia. This is because the Ethiopian Orthodox Church believes that Ethiopia has been counting the years starting right after the birth of Christ.
The way Ethiopians measure time is also different from the West. The clock starts at 6am western time and runs until 6pm. Therefore 8o’clock in western time would be 2 o’clock Ethiopian time. Because Ethiopia is close to the Equator the sun rises at around 00:30 Ethiopian time and sets at around 12:45 in the evening (6:45 western equivalent) all year round. Ethiopia is 3 hours ahead of GMT (Greenwich Mean Time). The years run in a four year cycle bearing the names of the Gospels with the year of John or Yohannes (Amharic) is being the leap year.
