Yay. We have a moon. It's very important to us. And it almost nearly, but doesn't quite, fit the solar year.
Lots of measurement problems come from that source.
Everything we measure is based on arbitrary standards, including metric. Sure they made sense at the time. Tech inertia keeps them in place.
We still drive automobiles with pieces of metal thumping back and forth after exploding fuel and atmosphere are ignited. Very inefficient.
It is what it is.
A bright spot is that with enough random chaos, a reasonable system may have a chance at eventually emerging. We certainly have the random chaos.
I'm not holding my breath.

They did.
That is why there are 60 minutes in a hour and 2 sets of 12 hours in a day. :)
The only less practical base numbers they could have picked besides 10 is 11 or 13.
