    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.

      12:30 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.

      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

        Perfectly illustrates how it doesn’t make sense.

        I can get behind

        • 11.30pm
        • 12.30pm
        • 1.30am

        Or

        • 11.30pm
        • 0.30am
        • 1.30am

        But

        • 11.30pm
        • 12.30am
        • 1.30am

        just doesn’t make sense.

          You start counting the hours to the next noon at midnight, duh. That’s why it’s ante-meridian, and the beginning of a new day. If you want to go around calling it 00:30, most people would understand, even in America.

          Did you mix up the first and third place? Because if 12:00 is “m”, it makes more sense for 12:30am to be night.

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

      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.

      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

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