I'm not even a programmer, but I can tell that dates are ambiguous a lot of the time.

e.g. dd/mm/yyyy (British) and mm/dd/yyyy (USA) can be confused for the first twelve days of every month.

So, given the high volume of international communication, I think we should hand-write months in full, or at least as the first three letters (Jan, Feb, Mar, ..., Dec)

We should also abandon three-letter acronyms (but that's another story).
