Except that for such an idea to work, you need to impose a kludge: the
365th day (not to the mention the 366th during leap years) would not be
able to belong to *any* week otherwise it would throw the entire
synchronisation askew!

As if those poor souls born on February 29 don't have enough grief
already! Only one birthday every four years. Now we'd be taking their
"rightful" place in the week away from them, instead tacking them onto the
year as some kind of left-over afterthoughts. :)

(BTW, at least one such calendar has already been devised, albeit for
literary purposes: by Tolkien for _The Lord of the Rings_. If memory
serves, his solution for the excess days was to not only deprive them of a
place in any week, but to put them outside the months as well.)
