I didn't even mention date formats. It's only 10/10 using the Gregorian calendar. There's still the Islamic, Indian, Chinese Hebrew, and other calendars in use around the world.
I don't know too much about the others, but the Chinese calendar is used purely in ceremonial and cultural contexts and is not really used in everyday life.
Edit: Okay so I checked, all of these calendars are used alongside the Gregorian one, mostly for religious or ceremonial purposes. Meaning if you asked a person from such a country what date it is today, they would in all likelihood answer the Gregorian date.
Once again Europeans assume the rest of the world is identical because Americans are the only ones bothering to correct them.
Quick! Name all the countries that use mm/dd/yyyy!
