I mean, do they say “I sleep at 9pm” or more like “I sleep at 2100 hrs” even while they are talking informally? 2100 hrs sounds very formal to me, but yeah, I was just wondering if they used 24 hour format for only official and government proceedings and used 12 hour format for casual stuff.

    Wait till you hear how Japan does things. If something closes at 1a or 2a, quite often the signage says 2500 or 2600 instead of 0100 or 0200 to denote that it’s a holdover from the previous day.

    It depends. You might say something like “I’ve got a meeting from 12 to 14”, which is perfectly natural. But also a lot of the time you might just say “I go to bed at 9” because the context makes it obvious that you mean 9 in the evening. Most people don’t go to bed in the morning. Unless you do, but then you would probably give context “I’m going to bed at 9 in the morning, because I work nights”, for example.

    Instead of 9pm I would say 21 o’clock (or in German 21 Uhr), if it is obvious I’m talking about the evening, I might also say 9 o’clock (9 Uhr)

    As far as I know, no one ever says “I sleep at 2100 hrs (twenty-one hundred hours)”. We say “I sleep at 9 o’clock” or “at 21 o’clock”). Then of course change o’clock with your lagnuage’s equivalent such as “uur” or “Uhr” in Dutch and German for example. Pm or am is almost always derived from context, and if it’s not you can add “in the morning/afternoon/evening”.

    Context makes it obvious. On the rare occations when it doesn’t, I usually add “in the evening” or “in the morning”

    In text Comms I use the 24h format but since I was a kid I learned to read the 24h in 12h format. I mean if I check the clock and it’s 18:00 I won’t think “it’s 18 o’clock” but “it’s 6 o’clock”
