We believe everyone has 12 months in a year. But a country in Africa is unique for its calendar with 13 months.

A 30-day calendar is used in Ethiopia for the first 12 months. But Pagume, the final month of the Ethiopian calendar, has six days in leap years and five days in regular years. One year has 365 days, 6 hours, 2 minutes, and 24 seconds on the Ethiopian calendar. Since 2014 began in September of last year, this means that they’re seven to eight years behind the rest of us. Ethiopians then celebrate the start of the new year on September 11 or September 12 if it’s a leap year. Because of this, the country celebrates more public holidays than other nations around the world.

Many people use the Gregorian calendar, but in traditional Ethiopia, the old calendar is still in use. If you’re traveling to Ethiopia, make sure to check the dates first!
