What is the advantage of using degrees (e.g. "30 degrees") versus radians (π/6)?
Regardless, your observations seem to come down to "12 is highly composite and we use highly composite numbers for time"—valid, but interesting?

Meanwhile, your response got me to look up whether there's a metric equivalent to degrees or radians. Apparently that exists and it's a measure called Gradians. There are 400 Gradians in a circle, and 400 is not divisible by 12. I guess that idea went the way of the French Republican Calendar.
And apparently, in what I have to assume is a related use:
> In surveying, the gradian is the default unit of angles in many parts of the world.

If you ever fooled around with your calculator in school, you probably noticed that it provided angle measurement conversion between degrees, radians, and gradians; the idea has certainly not gone the way of the French Republican Calendar.
