I don't see what the problem is. The Chinese New Year starts on a different date than in western countries, just by making equivalences you know what date we are talking about.
If we are talking about today, it would be the corresponding day of 2014 in the Ethiopian calendar, but it would still be today. And if we are talking about an event six months ago, we would just have to make calculations or look at both calendars,
But on a day to day basis it doesn't affect. Calendars are arbitrary divisions of time.
I cannot agree more. Indeed, calendars are just arbitrary division of time because there are different types of calendars in which a country uses. It just happens that Ethiopia uses a different one compared to what most of the countries uses. As a matter of fact, there are even more regions that use other type of calendar unlike what we commonly know and use in our every day lives. It's a matter of preferences, culture, and tradition. And I think there wouldn't and shouldn't be much of an issue about it since they are still living their lives 'today' and experiencing all the things the we encounter in their country as well regardless of the calendar they use. They have their own battles and struggles like any of us and surely they are still updated on the current happenings despite the unmatched date used. For sure, they are well-aware of the difference of their calendar to us, hence, are also aware on how to relate their dates to international dates if they were to check international news.
Regarding hosting Olympics and cups, I guess this matter would be thoroughly discussed before making any move. Since the people behind those tournaments know that Ethiopia is years behind, they would surely not make anything that would violate or in any way make Ethiopian feel bypassed. This matter should be organized and planned beforehand and if there's a conflict, then better not push it through so that it won't stir argument and chaos. After all, if the country's government won't allow, the event will not occur. Better not insist and respect the country's stance than to make an issue.
