    Rearranged argument order. day month year makes more sense.

    Revision 1.12  2001/05/27 03:44:03  rbowen
    Need to mod return value by 7.

    Revision 1.11  2001/05/27 03:41:31  rbowen
    This seems to work on all the dates that I've tested it for. More testing is
    needed.

    Revision 1.10  2001/05/27 03:13:57  rbowen
