Moveable feast

In Christianity, a moveable feast or movable feast is a holy day — a feast day or a fast day — whose date is not fixed to a particular day of the calendar year but moves in response to the date of Easter, the date of which varies according to a complex formula. Easter is considered by some to itself be a "moveable feast".
By extension, other religions' feasts are occasionally described by the same term. In addition many countries have secular holidays that are moveable, for instance to make holidays more consecutive; the term "moveable feast" is not used in this case however. 
Further, by metaphoric extension to mean a party on the move — or simply as a misnomer — Ernest Hemingway used the term A Moveable Feast for the title of his memoirs of life in Paris in the 1920s. This usage has become a popular phrase in food contexts, with several catering companies adopting it as their name.
