Case and point as to why it's confusing lmao

He did say it always fucks him up :D

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.

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

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

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

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)

But luckily unambiguous.

By the definition of post meridian, though, half past noon should be 0:30 pm.
