Twelve months a year, why Ethiopia has thirteen months?

In Ethiopia, they have a tourist slogan: enjoy the sunshine for thirteen months a year. In other countries, we only have twelve months in a year. Why is Ethiopia only 13 months old? What is the reason? Then let's see how the calendar in Ethiopia is different from other countries.

Actually, it's not the same or accurate. The method of calculating the year is similar. In Ethiopia, the first 12 month is 30 days per month, the normal years in other months are 5 days, and the leap year is 6 days. The leap year is regarded as the 13 month. Although all countries use the Gregorian calendar, Ethiopia insists on using its own method. If you are in Ethiopia now, you can be eight years younger because the date there is about eight years later than the Gregorian calendar.

According to local customs, the first month of 13 is "voluntary labor month", and all employees and workers in the city have to do unpaid voluntary labor. The usual salary is also paid according to the local calendar. This 13-month calendar is said to be a relic of the disagreement between the churches in Rome and Ethiopia thousands of years ago when they argued about God's "date of manufacture".

The last month in Ethiopia is the thirteenth month. It is called Pagume, which comes from the Greek word epagomene, meaning "forgotten time in a year". The normal year is five days, and the leap year is six days. Modern Ethiopia still uses its own calendar. Due to the time difference, many people who travel to Ethiopia are not used to the timing habits here and will find it inconvenient. ?
