Hi, james2dope

If I were planning such a project I would go to http://rudy.ca/doomsday.html 
for 
help and inspiratioin and links to other such the same.
It's called the Doomsday Algorithm, and it was originally created by 
Dr. John Conway, a very interesting mathemetician. 
Dr. Conway devised a way to determine what day of the week any date in history
would fall on so that you could do the calculation in your head.
I think that if you can do that calculation in your head, you won't have too 
much
trouble converting it to Python.
You will have to pay particular attention to Easter Sunday thou, as this date 
is very rarely the same on any two consecutive years.
Also, a search for "Doomsday Algorithm", "calendars, Python" and combinations 
of
such on google will prob'ly yield many free sources of completed scripts and 
info to
get you going.
