I guess I truly don't understand this comment, like I accept that hours divide our day into 24 segments, of which 12 are represented on the face of a clock.

I also accept that these hours are divided into 60 segments of which 5 are expressed between each of the 12 hours - which of course logically follows through basic division.

I even know the origin of O'Clock "On the clock" and contrary to the post why 6 means 30 (again this part is just math).

What I am referring to are the finer points of why 12 and not 24, or even why divide the day as 24 and hours into 60 minutes. I guess perhaps I do live in a different world, I can of course easily obtain the answers to both these questions through a simple search. My comment was more in regard to how such knowledge is something I didn't have on a holster, given that my day-to-day isn't predicated on knowing it.

I will also say, all knowledge is acquired. You by default, don't know anything, and have to learn it through experience and education. I make a point of being excited when people don't know something, especially if it's something I'm passionate about. This is actually a concept expressed well in this comic.
