World War II is generally considered to have ended in 1945, with the exact date depending on the theater being discussed.

Key end dates

  • In Europe, the war effectively ended when Nazi Germany surrendered unconditionally; this is commemorated as Victory in Europe (V-E) Day on May 8, 1945 (May 9 in the Soviet Union and parts of Eastern Europe due to time zones).
  • In Asia and the Pacific, Japan’s formal surrender aboard the USS Missouri on September 2, 1945, is widely marked as the final end of World War II worldwide.

Why multiple dates?

  • Some historians and governments emphasize August 15, 1945 (V-J Day), when Japan announced its intention to surrender, as the practical end of the war, since major combat effectively ceased after that point.
  • Others highlight September 2, 1945, because that is when Japan signed the formal Instrument of Surrender, giving a clear legal endpoint often used in official timelines and commemorations.

Simple takeaway

  • For most general purposes:
    • End in Europe: May 8, 1945 (V-E Day).
* End globally: September 2, 1945 (Japanese formal surrender).
