Celebration of an anniversary of a special event…
jubilee
A jubilee is the celebration of the anniversary of a special event, or it’s the anniversary itself. Which basically means it’s a birthday party.
Here’s something you might not know: the word jubilee comes from the Hebrew word yobel, which means “ram’s horn trumpet.” If you’ve ever celebrated the Jewish New Year, it’s possible you’ve heard a ram’s horn trumpet played to mark the jubilee. In Judaism, the Jubilee Year is a year of freedom from enslavement which is celebrated every fifty years. But that horn gets played every year. What’s a jubilee without a ram’s horn trumpet?
