> (2) DDMMYY This is unnecessarily "difficult" for a human and a computer to sort and parse eh? it's trivial for humans to parse. Most of the world uses that format in day-to-day usage, albeit with some kind of separator of course. it's also absolutely trivial for a computer to sort and parse, of course. saying it's "unnecessarily" (to redirect the quotes) difficult, you may as well say decimal itself is unnecessarily difficult. just use day of year, 1-365. you're splitting hairs here that don't need to be split.
