actually, it’s almost never dd/mm/yyy, but dd.mm.yyy, and yyyy-mm-dd. Japan is one of the few offenders, almost everywhere else the separator can be used to identify the format.

Australia also uses DD/MM/YYYY. You see ISO dates here and there but it's not as common.

I didn't mean about the separator at all, just the ordering. But good point.
