I used to have a C function that would compute the day
of the week from any given date.  You could pass it a
date in the form yymmdd, and it would return an int
in the range 0 - 7, where 0 was invalid date, 1 was
Sunday, 2 was Monday, and so on.

But I've lost the function.  Can anyone email me such an
animal?  Or even just describe the algorithm for computing
the day of the week?  Thanks much!
