Victory over Japan Day (also known as V-J Day, Victory in the Pacific Day, or V-P 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 – August 15, 1945, in Japan, and because of time zone differences, August 14, 1945 (when it was announced in the United States and the rest of the Americas and Eastern Pacific Islands) – as well as to September 2, 1945, when the surrender document was signed, officially ending World War II.
