Every clock is a base 10 system. The numbers go 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 & 12.
NONE of the other numbers are in any other base other than the base 10 system. Clocks are NOT a base 12 system.
No one uses feet and inches. HECK, even I didn't use feet and inches and I went through the first few formidable years in Scotland.
Again, the dates are all written in base 10 numbers; and who the hell cares if there are more factors of 12 than there are of 10. No one cares.
Why not base 60? The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60. What's your point???
Why don't they teach base 12 in school??? Because no one gives a crap about it, and it's IRRELEVANT!!!
normal clocks are still basically a base 12 system
