Getting the day of the week, in the Gregorian calendar, for a given date is
pretty straightforward. I thought we publihsed it online somehwere on the
Royal Observatory website, but I can't find it. However, wikipedia has the
algorithm:

An algorithm to calculate the weekday of Jan.???1th given a year is not
obvious at all.  Just the opposite: the more obvious an external fact is,
the easier (and more appropriate) it is to incorporate it to the
specification because it does not cause any distraction from the main
subject.
Cheers,
Chris
