Question

What’s the logic behind ante meridian and post meridian? Why were they named like that

Answer 1

Because PM basically means "after noon" if noon is 12 than any time after it is PM including 12:00:01 so it makes sense to say 12:xx is PM and making 12 itself PM also makes sense cause just a tiny fraction of a second after its already technically after 12. That's what I think.
