The country where it is currently the year 2018 is Ethiopia. Ethiopia uses the Ethiopian calendar, which is approximately 7 to 8 years behind the Gregorian calendar commonly used worldwide. This difference results from an alternative calculation of the date of the Annunciation of Jesus. The Ethiopian calendar consists of 13 months, with 12 months of 30 days each and a 13th month having 5 or 6 days. The Ethiopian new year, called Enkutatash, falls on September 11th of the Gregorian calendar, making the current year 2018 in Ethiopia when the rest of the world is in 2025.
