The most useful way long term is to do year-month-day. The most useful in the very short term is day-month-year. Month-day-year only makes sense if you are most interested in the month over days or years. (I.e. time scale of financial quarters.) Granted, it doesn’t take long to read a whole date any way you write it, so all the arguments seem to be a lot about nothing in the bigger scheme of things.
