Answer Germany invaded Poland on September 1 and on September 3, 1939 France and Britain declared war on Germany.

However, despite the fact that the Allies did not declare war on Japan until December 1941, Japanese aggression included the occupation of Manchuria as early as 1931, and open war with China between 1937 and 1945. Their plans to control the western Pacific prompted their attack on the US fleet.

By convention the date generally given by historians is 1 September 1939, when Germany invaded Poland, but it wasn't an official war until 3 September 1939, when England and France declared war on Germany after Germany's invasion of Poland. It ended on September 2, 1945 with the surrender of Japan, after the United States dropped two atomic bombs on the Japanese cities of Hiroshima and Nagasaki.

The following other events are occasionally cited as possible starting points:
  • 3 September 1939: Britain and France declared war on Germany following the German invasion of Poland.
  • 7 July 1937: The Japanese invasion of China (the start of the Second Sino-Japanese War).
  • 1931: The Japanese invasion of Manchuria.
  • Others argue that the two world wars are one conflict separated only by a "ceasefire."

    Here are other significant dates of the war:
  • 10 June, 1940: Fascist Italy declares war on Britain and France.
  • 7 December, 1941: Japan attacks America without any declaration of war.
  • 8 December 8, 1941: America declares war on Japan.
  • 11 December, 1941: Germany and Fascist Italy declare war on America.
  • 8 September, 1943 Fascist Italy surrenders.
  • 13 October, 1943: Italy declares war on Germany.
  • 19 April, 1945: German forces in Italy surrender.
  • 8 May, 1945: Germany surrenders (VE Day, Victory in Europe Day).
  • 2 September, 1945: Japan surrenders (VJ Day, Victory over Japan Day). General Okamura Yasiyi submitted surrender to Douglas MacArthur and Admiral Chester Nimitz on the USS Missouri in Tokyo Bay.

  • The end of WWII was in 1945. However, there were some Japanese soldiers on isolated islands in the Pacific who never got the message that the war ended (or they believed it was a trick) and they fought on for years afterward. Believe it or not, the last Japanese soldier to surrender was Second Lieutenant Hiroo Onada who emerged from the Philippine jungle in 1974 to finally surrender. His book, "No Surrender - My Thirty-Year War" is fascinating.

Answer The commencement of World War 2 has different dates in different countries. To the Americans, World War 2 started on December 7th, 1941, when Japan attacked Pearl Harbor. To Britain, France, Canada, Poland, World War 2 started on Sept. of 1939, when Nazi Germany attacked Poland. To Czechoslovakia, World War Two started in March of 1939, when Nazi Germany attacked them. To the Ethiopians, World War Two started in 1936, when Italy attacked. To the Chinese, it dates back to 1931, when Japan occupied Manchuria. The Russians date the start in June 1941 (not 1939). Answer World War 2 "started" on the 3rd of September, when Britain and France declared war on Germany. (They had a treaty with Poland). The war ended in early May 1945 in Europe, Hitler having committed suicide in April of that year. The war in Japan ended after their surrender to the Americans in response to the A-bombs dropped on Hiroshima and Nagasaki - respectively the 6th and 9th of August 1945. Answer By a long-standing convention, the dates are usually given as 1939-1945, except in Russia, where they are usually given as 1941-1945. If one gives another starting date, one conveys the message that one is making some point or other, for example, that one is claiming that the sufferings of the Chinese have not been given the attention they deserve. As for the notion that WW1 and WW2 were one war with a 20-year truce, this is not meant literally.
World War II began on 9/3/39, 2 days after the invasion of Poland. Britain and France ordered Germany to halt the invasion of Poland and when they refused, Britain and France declared war.
