jubilee

A jubilee is often used to refer to a celebration, commemoration, or anniversary. "Jubilation" for joyful celebration comes from "jubilee". The term comes from the Hebrew Bible, initially concerning a recurring religious observance involving a set number of years, that notably involved freeing of debt slaves. Emperors of ancient Rome customarily marked anniversaries of their rule with celebrations, although they did not use the term "jubilee." Jubilee is also a term used in Roman Catholicism for special years. The term came into English usage from translation of the Bible, together with customary celebration of a reign, and at least since the 19th century is regularly used to denote the celebrations associated with the reign of monarchs after a milestone number of years have passed.
