As an American, I personally hate that standard, and usually use YYYY-MM-DD wherever possible, and only revert to MM-DD-YY on documents that require it in that format. I get that MM-DD follows the conventions of speech ("the event is on May 7th"), but it's really ambiguous when written in all numbers.

"The event is on the 7th of May"

Unfortunately, that's just not the way people talk about dates here. Maybe it's because we use a backward date order, or maybe it's a self-reinforcing loop, but that just doesn't sound natural, even to me.

Isn't it MM/DD, not mm.dd in US? E.g. 8/23, not 8.23. My point is that it is more or less insane to start inventing new date format with zero regard to formats in other countries.

Eh, people will use anything, I've also seen 8-23. 8.23 certainly isn't a stretch.

You haven't been dealing with the U.S. much, have you? To be fair, most of the fun comes from their use of ancient standards rather than new ones, but they aren't exactly known for consulting with other countries. Then again, at 300 million people it's a little difficult to blame them.
