In Christianity, a moveable feast or movable feast is a holy day -- a feast or a fast -- whose date is not fixed to a particular day of the calendar year but moves in response to the date of Easter, which date varies according to a complex formula.

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 but with the meaning of a party that was on the move, Ernest Hemingway used the term as the title for his memoirs, A Moveable Feast, of life in Paris in the 1920s. This usage has become a popular phrase in food contexts.
