Ethiopians are some seven years younger than the rest of the world! Ethiopia uses the Julian calendar whereas the rest of the world follows the Gregorian which is seven and a half years ahead. In the Julian calendar, a year comprises thirteen months; twelve of these months have 30 days. The 13th month has 5 or 6 days depending on leap year. While the rest of the world crossed over into the millennium in 2000, Ethiopia is still in the 1990's. Ethiopia's second millennium will take place in September 2007. Ethiopian time is three hours ahead of Greenwich Mean Time (GMT).
Days and nights are of equal length as in other equatorial countries. Each day is 12 hours long. An Ethiopian day starts at 7 am (counted as 1:00) and ends at 7pm (12:00 Ethiopian time). While you are in Ethiopia, in order to tell what the local time is, just add 6 hours onto your watch reading.
