August 15th, 1945
Soldiers in Pearl Harbor gather around a radio and listen as Japan accepts the Potsdam Surrender terms. The day moving forward is also remembered as V.E. Day or Victory in Europe Day.
August 15 is the official V-J Day for the UK, while the official U.S. commemoration is September 2nd. The name, V-J Day, had been selected by the Allies after they named V-E Day for the victory in Europe.
