dd/mm/yyyy is the way to go, imo

Well for one, I've never heard of saying the month as a number in regular speech. Do you really say "The Second of the Seventh"?

I would say (and as far as I know this is the typical way throughout the U.S.) is exactly as I wrote it -- August Thirtieth, Nineteen-Eighty-Four (perhaps shortened to just Eighty-Four). Which matches to the way we typically write by numbers -- 08/30/1984.
