Depends on which side you are focusing. In Asia, the war really starts around 1937 when Japan invaded Manchuria (China). Most likely, though, you are looking for the event that sparked the European side of the conflict: the invasion of Poland by Germany on September 1, 1939 that brought England and France to declare war on Germany (as part of a promise to protect Poland if it were invaded).
