I just read somewhere that Good Friday is “a moveable feast.”  Hmmm, I said. What does that mean? 
Ernest Hemingway wrote a novel called A Moveable Feast,
 which is a collection of memoirs about his years in Paris. Someone 
wrote that Paris is “a moveable feast.”  Somehow, though, I don’t think 
it is a moveable feast in the same sense as Good Friday. Maybe Hemingway
 moved around Paris feasting on…things.
When I looked it up, Wikipedia said a 
moveable feast is a holiday whose date varies, depending on different 
things—as opposed to a “fixed feast” like Christmas, always December 
25.  The date for Good Friday, it said, depends on the date of Easter, 
which is also a moveable feast.  According to FashionGets.com, 
Easter
 is considered to be a moveable date because the first council of Nicaea
 in 325 AD declared it to be the Sunday after the full moon after the 
vernal equinox. It was then changed by the Gregorian calendar in 1582. 
That information was not quite confusing enough for me, so I also considered this mind-boggling erudition, found here: 
The tables which appear here and, in more detail, in the Book of Common Prayer
 can be used to determine the date of Easter. These tables were compiled
 by the then Astronomer Royal, the Revd James Bradley (1673–1762) for 
the Calendar Act 1750 (by which the Gregorian Calendar was adopted in 
Britain), and the effect of them is mathematically identical to the more
 complicated tables devised in 1582 for Pope Gregory XIII’s reform.
In another sense, a website called “Moveable Feast”
 is about an organization in Baltimore that delivers healthy meals, 
groceries, and nutrition counseling to people who suffer from AIDS. 
There’s a similar organization with this title in Lexington, Kentucky.
Oh, dear. What to do with all that?  The 
thing is, a moveable feast changes around, whereas a fixed feast does 
not.  The title has an important ring to it. Of course, we don’t call 
holidays “feasts” in America these days, although we often do feast on 
holidays.  I like thinking of Easter and Christmas as feasts of love and
 sharing. And I like thinking of a group whose purpose is to nourish 
people with AIDS—a feast of feeding, loving, giving.
