Yes - in fact, your method makes sense - as would yy/mm/dd. Guess we Americans stick to how we say it - not how it would make any mathematical sense - so our 'calendar clocks' cycle in the middle column first, the left column second, and the right column last. Guess the Romans stuck to there idiotic numbering system for centuries as well. Some kind of strange hubris I suppose.
But - at least here, we get Pi Day! A celebration of total nerdosity!
