@wxcafe @sng this sounded interesting so I had started looking at the breakdown (https://en.m.wikipedia.org/wiki/Date_and_time_representation_by_country, pink are the 24-only countries) and it seems like the countries that use 24 hour often have many reasons to that affect everyday people rather than just specialists, trains and nightlife and lots of time zone crossing, international flights... Real ambiguity and lots of pressure to be clear
I do 24 written now, 12 if we're speaking since now I have that ambiguity, too, it's very relevant, but where I grew up there was no overlap except a few hours after dark, there were simply no reasons to talk about 0200, nothing was open, you'd not be coming home at it, it didn't exist. XD also it would be really really hard to break the habit of saying "o'clock" in favor of "hours" , I think, which reads number not time to me
I bet it would be fascinating to look at when the things were adopted and see, like does this shift with added trade? Urbanization? Because it's a really funny map!

@pmosetc @wxcafe In Korea the use of 24 hour time goes pretty directly back to the war. It’s far more common in older people.
