Through the ages, people have developed many different calendars to organise time, and as of 2011, there are approximately 40 different calendars in use around the globe. While most Westernized countries use the Gregorian calendar, the Ethiopian calendar is based on the Egyptian and has 13 months---12 with 30 days and the last month with six days on a leap year and five days on all other years. Converting dates between calendars is easy when you use one of a variety of online tools to make the conversion.
Convert the Ethiopian year to the corresponding Gregorian year by subtracting 5,500 from the Ethiopian year. Each Ethiopian year overlaps two Gregorian years, because the Ethiopian year starts in September of a Gregorian year. For example, Ethiopian year 7511 started in September 2010 and runs into 2011.
Take a Gregorian calendar for the current year and following year. Starting at September 11, which is the Ethiopian new year, and the first day of the month of Meskerem, count and, using a highlighter pen, mark on the calendar each 30-day month, chronologically: Meskerem, Tikimt, Hildar, Tahsas, Tir, Yakatit, Maggabit, Miyazya, Ginbot, Sene, Hamle, Nehasa and, finally, Pagume, which has five days.
Factor in leap years. Ethiopian leap years occur every four years. The new year starts on September 12 in a leap year, such as Ethiopian year 2000.
Hang your calendars up. They will now display both the Gregorian and Ethiopian dates.
Visit a website such as Isotropic.org, Selamta.net or Gebeya.net.
