[Tutor] datenum

[Gregor Lingl]

Hi, Cliff!
There is a powerful *new* datetime-module in Python 2.3 
Its documented here (and in the Global Module Index):

http://www.python.org/doc/current/lib/module-datetime.html

Maybe the toordinal method of the date class is something you could use:

 >>> from datetime import date
 >>> date(2003,9,25).toordinal()
731483

(Maybe you will need anoter "some zero" ?)

Have a look at the docu. You cerainly will find something which
at least will make your life easier.

Regards, Gregor
