540. Which country in the world has a different calendar?
It is quite an unknown that the whole world, except Ethiopia, has adopted Gregorian calendar. On the other hand, Ethiopia has accepted the Coptic calendar, which is quite different from the Gregorian calendar. The Coptic calendar has 13 months of which 12 months comprise of 30 days each, and a 13th month at the end of the year called the intercalary month usually has 5 days and 6 days in a leap year. The country of Ethiopia celebrates New Year on September 11th.
The relationship between Ethiopian and Gregorian calendars varies whenever the Gregorian calendar misses a leap year. The difference in year numbering is because the Ethiopian Orthodox Church disagrees with the Roman Catholic Church about when Christ was born. The calculation of time is also dissimilar in Ethiopia as hours are counted from down. So the next time, while on September 11th(today) you are engaged in your routine schedule, Ethiopia will be celebrating New Year!
Happy New Year Ethiopia.
