In the United States, which date is commonly associated with V-J Day’s 1945 announcement?

In the United States, V-J Day’s 1945 announcement is commonly associated with August 14, 1945.

President Harry S. Truman announced Japan’s surrender to Americans on August 14, 1945, in Washington time. Because Japan was ahead across the International Date Line, the emperor’s radio broadcast occurred on August 15 in Japan. This time-zone difference explains why both August 14 and August 15 appear in historical accounts of V-J Day.

The term V-J Day means Victory over Japan Day, paralleling V-E Day, or Victory in Europe Day. In the United States, September 2 is also significant because the formal surrender document was signed that day. Some countries use August 15 for their commemoration, while the United Kingdom traditionally observes that date.

Therefore, the answer depends on whether a source means the public announcement or the formal signing. This question specifies the American announcement date, not the ceremony in Tokyo Bay.
