Jubilee

From the English word jubilee meaning "season of rejoicing", which is derived from Hebrew יוֹבֵל (yovel) "ram, ram's horn; a jubilee year: a year of rest, prescribed by the Jewish Bible to occur each fiftieth year, after seven cycles of seven years; a period of celebration or rejoicing" (via Late Latin iubilaeus and Greek ἰώβηλος (iobelos)). In Latin, the form of the word was altered by association with the unrelated Latin verb iubilare "to shout with joy".

It may also refer to African-American folk songs known as Jubilees.

In popular culture, Jubilee is the 'mutant' name (a contraction of Jubilation Lee) of one of the protagonists of Marvel's X-Men line of comics.
