more about EASTERSUNDAY

[Andreas J Guelzow <aguelzow@math.concordia.ab.ca>]

Just for your information, Gnumeric 1.9.15 includes the following
functions. (Of course Gnumeric has lots of functions that are not
included in the current OpenFormula draft.) Note that while in first
glance it may seem that may of these are just fixed offsets from
EasterSunday, the interpretation of an omitted year, changes that: the
dat for GOODFRIDAY() may be in the year following the date for
EASTERSUNDAY or not., since both refer to the next such holiday.
