I'm just glad that nobody in Europe seems to use YYYY/DD/MM. This means that the format "YYYY-MM-DD" is unambiguous and the lexical ordering of dates is the same as their natural ordering[1], which is useful for sorting files in folders.

Except at DST switch.

DST and timezones in general are an abomination anyways.
