Compulsion

we like to stay vigilant of the Sun's position relative to our meridian

Whenever a system puts in that format I just change it back to AM/PM, I just don't like it, I like to have less numbers (bigger numbers) on my screens... Not that it confuses me or anything.

Nope “military time” as you call it, all the way babbyyyy

Some people use one 24h, other am/pm, but everything related to clocks always has the choice to use one or the other configurable. Most people use 24h format and most public info and tv shows and all that usually uses 24h. When I was a kid am/pm was used in more places, not sure why.

Basically everyone knows how to use both, it's obvious and straightforward, I don't think I've ever seen anyone ever not being able to know the time whichever foat was shown. Am/pm comes more often in informal talking when context of the conversation is obvious since it's much easier to say snack at 3 than snack is at 15.

I don't think I've ever seen any country other than the USA using the 12 hour system

It's used in spoken language, especially in combination with quarter past and stuff, but not in writing in not in the setting of digital watches

I never claimed superiority. I only said that since Europeans are accustomed to 24h system, the joke becomes difficult to understand, because we don't have this problem.

But if you perceive this as some sign of superiority, well...
