United States of Arbitrary
I'm with you as far as the metric system goes, but month day year is how it's spoken, so it makes more sense to me. Also, it's sort of irrelevant since a lot of countries have their own way of notating it (some of them even do it like the US, or we do it like them, I don't really know the chronology) and I don't think any of the Orthodox churches have adopted the Gregorian calendar and the International Standard is YYYY-MM-DD.
Today is November 28th.
