It could return a tuple or something then. But if I want people to choose:
either input "Nov, 23" or "12/6/99" or "1 December 2000", I don't want to
check too much. There are much date processing programs (date, I think) that
do this intelligent. You could also let the above think depend on the timezone,
if it's an american timezone, take the american way, else, take the
european way. But returning a tuple on 132 days seems better to me.

Gerrit.
