The 1940 Summer Olympics, officially known as the Games of the XII Olympiad, were originally scheduled to be held from September 21 to October 6, 1940, in Tokyo, Japan. They were rescheduled for Helsinki, Finland, to be held from July 20 to August 4, 1940, but were ultimately cancelled due to the outbreak of World War II. Helsinki eventually hosted the 1952 Summer Olympics and Tokyo the 1964 Summer Olympics.
