I tend to organize things, photos, folders, correspondence, notes, by date, so labels start with yyyy-mm-dd which the computer quickly sorts into chronological order. This date format is called big-endian notation because the first in the series is the biggest item (the year), followed by the next biggest, and on to the smallest (the day). Of course, the existence of big-endian implies the existence of small-endian. Yet what might be called middle-endian - like December 17, 2013 - looks most pleasing to my eye, likely because I was raised in the states. According to the Guardian's Americans are almost alone in their use of mm-dd-yyyy.
