On what date was the Potsdam Declaration calling for Japan's surrender issued?

The Potsdam Declaration calling for Japan's surrender was issued on July 26, 1945.

The declaration was issued during the Potsdam Conference near Berlin. The United States, the United Kingdom, and China called on Japan to surrender unconditionally and outlined broad terms for ending the war. It warned that rejection would bring “prompt and utter destruction,” although the declaration did not explicitly mention atomic weapons.

President Harry S. Truman, British Prime Minister Winston Churchill, and Chinese leader Chiang Kai-shek were associated with the declaration. The Soviet Union did not initially sign it because it was still neutral toward Japan at that point. The Soviet Union declared war on Japan on August 8, 1945.

Japan did not immediately accept the declaration. The United States bombed Hiroshima on August 6 and Nagasaki on August 9, while the Soviet Union entered the war against Japan. Japan then accepted the declaration's terms, leading to Hirohito's announcement on August 15 and the formal surrender on September 2.
