All input routines, whether they're from a web-form, database, command
line, or anywhere else, only produce objects from the datetime module
for calendar data. That way the program logic doesn't have to guess
which format it's getting... I suppose I could do something like:

   def age(born):
        mx_born = mx.DateTime.Date(born.year, born.month, born.day)
        ...
