Jubilee is a celebration of a period of time, anniversary or other special occasions. The word jubilee is derived from the Hebrew yobel, meaning ram’s horn. In the ancient time, the jubilee was announced by the blowing of the shofar, a trumpet of ram’s horn, and as a result, the occasion came to be known as yobel, or jubilee. The Arabic word for jubilee is also yobel, and Turkish ellinci.
