Easter (or How to Calculate the Date of Easter)

I never realized how complex it is to determine the date of Easter. I thought the rule was "Easter is the first Sunday following the first full moon following the spring equinox." However, since nothing in christendom is that simple, here is a site that explains in some detail the history behind the ecclesiastical determination of the date of Easter for any given year. It also provides an algorithm with which one can compute the date of Easter for any given year. Or one can go cross-eyed at the Prayer Book's "Tables and Rules for Finding the Date of Easter Day," beginning on page 880.
