I find 12:00 a.m. and 12:00 p.m. incredibly confusing. It’s 11:59 a.m. and one minute later it’s suddenly 12:00 p.m. and you just keep counting until 12:59 p.m. before you reset the clock to 1:00 p.m. The literal meaning of p.m. (post meridiem) is after midday, which instinctively suggests that 12:00 p.m. is 12 hours after midday. If it would just start counting from 0:00 p.m. you wouldn’t have this problem. Of course it all makes sense if you’re used to it, but this is from my 24h perspective.
