The answer to "which country is it the year 2018?" depends on the calendar system used. While most of the world used the Gregorian calendar marking the year 2025, Ethiopia follows its own unique Ethiopian calendar. According to the Ethiopian calendar, in 2025 Gregorian it is the year 2018, due to a different calculation of Christ's birth and a thirteen-month calendar system. In summary:
- By the Gregorian calendar, it is the year 2025 worldwide.
- In Ethiopia, using the Ethiopian calendar, it is currently the year 2018.
Separately, Armenia was named "Country of the Year 2018" by The Economist for its democratic advances in 2018, but that is unrelated to calendar years.
