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.

      It’s not an “official” thing and usually rolls over based on the business.

      So let’s say one business opens at 10a and closes at 4a every day, they’ll say 10:00-28:00

      But let’s say a different company opens at 3a and closes at 10p, they’ll say 03:00-22:00

      You’ll notice that there isn’t an “official” reset of time, it’s only used when a business carries over past midnight till whenever they close the next day. You don’t really find anything going past about 4a though.
