When is The World War II Victory over Japan Day (V-J day) commemorated?

Field-Marshal Wilhelm Keitel submitted the capitulation of the Wehrmacht to Marshal Georgy Zhukov in the Soviet Army headquarters in Berlin-Karlshorst. To commemorate the victory in the war, the ceremonial Moscow Victory Parade was held in the Soviet capital on 24 June 1945.

The other World War II victory day, the V-J day (Victory in Japan Day) is commemorated in August.

Victory over Japan Day (also known as Victory in the Pacific Day, V-J Day, or V-P Day) is a name chosen for the day on which Japan surrendered, in effect ending World War II, and subsequent anniversaries of that event. The term has been applied to both of the days on which the initial announcement of Japan's surrender was made – to the afternoon of August 15, 1945, in Japan, and, because of time zone differences, to 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 signing of the surrender document occurred, officially ending World War II.

August 15 is the official V-J Day for the UK, while the official U.S. commemoration is September 2. The name, V-J Day, had been selected by the Allies after they named V-E Day for the victory in Europe.
