Japan has a broadcast time system. It can go from 11:00 -> 0:00 -> 13:00

So Japan gets a few things right, IMO, about time. We don’t do daylight saving. Places that stay open past midnight will list hours like ‘20:00 ~ 26:00’ to indicate closing at 2am which I feel pretty neutral about. We’re in the wrong timezone in my opinion and at least eastern Japan should move to UTC+10 or even UTC+11 so it’s not getting light at 3-something in the morning in summer.

However, the thing that drives me nuts is watching TV and it suddenly going to 0:00 at noon. Why?! This is doubly true for those who go 11 -> 0 -> 13 instead of 11 -> 0 -> 1. It’s completely irrelevant to anything in my life, so definitely just mildly infuriating to me. Maybe people with shiftwork schedules and blackout curtains might have some confusion.

Japanese broadcasting and newspapers usually use a modified 12-hour notation in which midnight is 午前0時 (0 am) and noon is 午後0時 (0 pm) […]
