12:00am is the middle of the night when many people (apart from Mike,
who, judging from the timestamps on his postings, never sleeps) are
asleep.  12:00pm is "the middle of the day, at least for farmers, when
one traditionally eats lunch.  Think of 12 as really meaning 0 and the
am/pm as being the high order bit of the time of day.

The point I'm unclear about is whether 12:00am belongs to the same day
as 11:59pm or as 12:01am.

I think that for as long as we've had a national currency, it's been
decimal.  Imagine how funny our spreadsheets looked when the stock
exchanges started pricing shares in $1/16ths.
