As someone who grew up with a 24-hour clock, I can deal with 12 hours. Usually there’s no confusion if your store opens at 7am or 7pm. But 12:30PM being a valid time and meaning ‘00:30 on the next day’ fucks me up every time.

12:30PM means 30 minutes after 12-noon. Anyone saying that and meaning the middle of the night is just wrong, and if that’s a genuine thing people do it would drive me quite mad. 30 minutes after midnight is 12:30AM

Literally this. I was never in the military, and I’m glad they literally can’t draft me unless they lower a lot of requirements really fast. But 24-hour time is just so much more sensible. There’s no “AM or PM?” follow-up question, no guesswork. It just makes sense. If they made metric time, I’d adopt that shit in a heartbeat.

12:30 AM is 00:30 though? They shouldn’t even have 12 on the clock, it should be 0 because the 12 hour clock is modulo 12.

This teaches you the value of terms like “half past noon“ and “quarter to midnight“

"Closes at 25:00" is funny too

12:30 pm is half-past noon. 12:30 am is half past midnight, or as you would say 00:30 The m is "meridian" which is noon (sun straight up) The a is ante/before and the p is post/after In olden days it was easier to look up and set your clock at noon than midnight.

It doesn't mean that.
