Why do you keep bringing "am" into this.
again none of what I said has anything to do with the definition of "am"

And why are you being so rude on what is clearly a silly thread?

My "argument" isn't that "midnight itself makes no sense"
My argument is that having the day start at midnight isn't how people intuitively conceptualize a day, and wouldn't it be nice if the calendar day more closely resembled our intuition about days (a contiguous daytime period followed by a contiguous nighttime period).
