Military Time vs 24hr? - Lemdro.id

Why is it that Americans refer to 24 hour time as military time? I understand that the military uses the 24hr format but I don’t understand why the general public would refer to it like that? It makes it seem like it’s a foreign concept where as in a lot of countries it’s the norm.

In the US, the 12-hour clock format is in widespread use, except in the military. That is why it’s called like that.
It’s interesting that it’s not as widespread amongst the public.As far as I know, the rest of the world either uses it or is able to understand it whereas I’ve had the opposite with Americans. I’m a very limited sample size though.
As far as I know the Japanese use it aswell. I learned 午後 and 午前 as vocab at least. (Am and pm)
