How we keep time is the dumbest
Why don't they just leave them the same??!!
Supposedly, this stupid nonsense is because "am" stands for "ante meridiem" and "pm" stands for "post meridiem" or "post mid-day". It's even stupider that "post meridiem" actually occurs around 11 in the "am" during daylight savings time. So for 7 out of the 12 months of the year (during DST), I think we may as well switch it to ...8am, 9am, 10am, 11pm, 12pm.
If you're not going to use numbers right, just get rid of em.
