Also why clockwise?
Earth rotates and orbits counter clockwise. It just seems more right

Earth rotates and orbits counter clockwise.
No it doesn't. It depends on the human perception of "up" and "down" which are completely arbitrary. We by convention see the North Pole as the "top" of the world but it could as easily be seen as Antarctica.
Well that depends on where you look at the earth from doesn’t it. It’s like saying ‘righty righty, lefty loosey’ which only holds true as long as you’re thinking about the top edge of the screw head.
Well, depending on which hemisphere you're standing in, at least. We arbitrarily set this idea that north = up in most depictions of the globe, but we could just as easily make Antarctica the top of the world and everything rotates the other way.
The reason why clockwise is what it is, is because sundials were first used to tell time in the northern hemisphere, where the shadows move clockwise. If it was in the southern hemisphere, they'd have moved counterclockwise (which would be clockwise).

Gift from ancient Mesopotamia. Mesopotamians love 12 & base 60. They also liked 7. Those numbers recur in their mythology.
Americans have a weird fixation with 💯. Where Americans might use percentages, I've seen Japanese plot values in [0, 1] (ie, pure proportions).
It's not about mythology or Mesopotamia. Those numbers are called highly composite numbers (HCN) and superior highly composite numbers (SHCN) and are great for doing calculations (especially divisions) in your head because they have a lot of factors. That's why they were used everywhere before calculators were a thing.
That's probably why Mesopotamians chose them: the convention traces back to them. Measuring angles in degrees also traces back to them.
Still, those numbers/units are quite arbitrary & introduce unnecessary conversions. Radians are dimensionless & require no conversion. Converting seconds to a more natural unit like days involves reintroducing those highly composite numbers that fit better in base-60 than the base-10 system we now use.

What is this?
My guess is there are only so many conversations you can have over whether a Silvertip Badger is superior to a Boar brush.
But there's a million razorblades people can argue about. Platinum, tool steel, carbon. And then there's which holder is the best. And then all the straight razor refinishing/refirbishing you could get into. Not to mention, strops, towels, soaps, sebum oils, styptics and on and on.

I'll be there at H:00.
I say we divide the day into 100 sections. No reason really I just think it’d be cool to party until 100 o’clock.
You might like reading about decimal time…

In Ethiopia they still use the tradition time where the day starts at the 1:00 which is our 6am. Then 12:00 is our 6PM, and it starts over. So they have 2 cycles of 12 hours, one for daytime, and one for night time. And it felt somewhat more intuitively in conversation too.
