It does support YYYY/mm/dd which is the international standard.
Curious - in Europe, do you do dd/mm/YYYY or dd.mm.YYYY? The latter should be straightforward to support, but former would conflict with mm/dd/YYYY that's already included.
In india we dd/mm/yyyy too
There is no such thing as “Europe” for these purposes, so it depends.
In France we do dd/mm/yyyy. Others do dots.
