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.
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.
the standard time that almost everyone uses is metric, i.e. is part of the metric system, its units are SI units. there was a system of decimal time, if that’s what you mean, developed in France during the revolution, where a day is 10 hours, each 100 minutes, each 100 seconds
so a decimal hour is 2.4 standard hours
a decimal minute is 1.44 standard minutes
a decimal second is 0.864 standard seconds
I think it’s cheating to call it metric if it’s not decimal. Even some of the oldest analog clocks had 24-hour faces, they were just a bitch to read in a watch-size. You still have to do stupid math to figure out duration past the 12 or 24, and even with the 60 minutes/1 hour. Nothing metric or superior about it.
how heartbeat? I have a metric calendar that only one other person likes. 13 months of 4 weeks of 7 days, with one day leftover for celebrating my birthday (because i decided we’re doing the calendar, the day off is my birthday suck it trebek)

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.
He did say it always fucks him up :D
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
As I said, it always fucks me up. The AM/PM indicator wraps at a different hour than the hours. Aaargh!

The French tried metric time. It was pretty quickly abandoned.

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.
By the definition of post meridian, though, half past noon should be 0:30 pm.
We use the 12 at both ends because there it is sitting at the top of the clock
It doesn’t mean that.
