Look at what date it is today, and then try to guess which one of these format is the one they are referring to.

Also: one of these is an ISO standard format. The other one is a format that no one would use. (DD/MM YYYY is in use, but no one would write YYYY-DD-MM.)

Don’t Americans do:

MM-DD-YYYY?

So it would stand to reason that an American commenter may be meaning

YYYY-DD-MM

And guessing based on todays date, tell that to commenters who check this post in 6 months

Americans do mm/dd/yyyy, but never mm-dd-yyyy
