I meant the same numerical date, e.g. Christmas is always December 25th, 
and so is a little easier programatically than the rules for Easter. If 
you meant that Sunday is never a business day, then yes, it was a bad 
example. :)

Sure, that's an alternative, but it seems a bit too much reinventing an 
already existing wheel. I was amused to see the script had the ill-fated 
Lee-Jackson-King day in it. Ideally, we'd want a Postgres table that 
describes the rules for each holiday, and then a function that reads it 
on the fly. Perhaps a project for another day...
