One can certainly see the advantage in an easily divisible year.
However, this pre-supposes that the year was designed to be 12 months. I
seem to remember, but won't spend a lot of time trying to confirm it,
that the year once was 10 months, and two months were added to honor
Julius Augustus something or other. Good they had the good sense then.
Perhaps that good sense should come now. Should we switch to a base-12
numbering system?? Some advantages:
1) clocks (time), compass readings, many tool sizes, the 12 inch ft.,
etc. could all be expressed decimally (in the new system),
2) twelve is more easily divisible than 10!!
3) U.S. and U.K could tell the rest of the world to switch to our
base-12/English measurement system.
Any other believers?
