Victory over Japan Day is the day on which Imperial Japan surrendered in World War II, in effect bringing the war to an end. The term has been applied to both of the days on which the initial announcement of Japan's surrender was made – 15 August 1945, in Japan, and because of time zone differences, 14 August 1945 – as well as to 2 September 1945, when the surrender document was signed, officially ending World War II.
