The country where it is currently the year 2018 is Ethiopia. Ethiopia uses its own unique calendar, the Ethiopian calendar, which is about seven years behind the Gregorian calendar used globally. This calendar has 13 months and its year numbering is different due to unique calculations by the Ethiopian Orthodox Church regarding the birth year of Jesus Christ. Hence, while the Gregorian calendar year is 2025, Ethiopia is still in 2018 according to its traditional calendar system.
