  Description: Zeller's Algorithm can be used to determine the day
of the week for any date in the past, present or future.
Actually the algorithm should work only for those dates starting
with the use of the Gregorian Calendar in the year 1582.
The Gregorian Calendar will be off one full day in the year 4902,
so this algorithm works for any dates between 1582 and 4902
