I'm looking at this from a "linguistic and cultural adaptability"
perspective, which is an ISO/IEC requirement. There are two dates where
Easter is celebrated, if you consider as well the Eastern Orthodox
observance. And then there are all the other holidays which have movable
dates in various religions and cultures which base such dates on a lunar
calendar.
I wonder whether the approach is to have a function called HOLIDAY(String
name, Number year), which you could call as:
HOLIDAY("Easter", 2009)
or
HOLIDAY("Easter-Orthodox", 2009)
or
HOLIDAY("Passover", 2010)
We could reserve strings for the major observances and then allow
implementation-defined extensions.
