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.
The average American is likely to have more interaction with American service men and women than Europeans. Most Latin immigrants I know use the 12 hour clock. While the 24 hour clock is preferred in many countries, they are not the countries that immigrate to the US in large enough numbers to influence us or expose us to the 24 hour clock like our own military does.
Wait, how would you know whether migrants use the 24 hour clock?
You're not supposed to say "we meet at fifteen thirty", you just say half past three or, in non-English languages sometimes "three in the afternoon".
You only write it as 24 hours because it saves you having to add extra letters to solve the ambiguity. When I interact with Americans I also write "three PM", it's just being polite.
IMHO, I don’t think that would change anything (with regards to immigrant influence).
EDIT
For those downvoting me, I’ll explain it more for you. The vast majority of the world currently uses the metric system. Only three countries officially use the imperial system (UK has mixed usage, including them would bring the number to four.). If the majority of the world uses one system, and the US hasn’t changed, how will migrants influence the country enough to change?
