Description:

    BUGFIX: due to a stupid error I uploaded the WRONG version - this is the working one
            (the old one was one day late :)

    Once upon a time I searched for a program to calculate the weekday out of
    a numreic date. I found a SHAREWARE program with GUI to do so ???!
    Whats up? There is absolutely no engenius a-logarithm (internal joke :)
    behind this! So use this as FREEWARE, just mention my name if you
    use it in your programs ...

date2day template:

    input: <int> day,month,year

    0: error (before 1.1.1801 - this should be enough
             if somebody knows a "day" before that please mail it to me)

    1-7: Monday-Sunday
