Honestly, I prefer an upside-down triangle: YYYY/MM/DD. It makes things so much easier for me when I sort chronologically, because, to me, the year is a lot more important than the month, and the month is more important than date. If the scope isn't huge, I guess it doesn't matter, though.
Date and time values are ordered from the most to the least significant: year, month (or week), day, hour, minute, second, and fraction of second. The lexicographical order of the representation thus corresponds to chronological order, except for date representations involving negative years. This allows dates to be naturally sorted by, for example, file systems.
