How long was it between first hostilities and WWII being recognized/called "World War II"?

For example:

  • 3 October 1935, Mussolini invades Ethiopia
  • 7 March 1936, Germany Invades The Rhineland
  • 12 March 1938, Hitler Seizes Austria
  • 1 Oct 1938, Germany Occupied Sudetenland
  • 1 September 1939, Hitler invades Poland (considered the beginning of WWII)

Where first hostilities 1935? Earlier?

Was the term WWII used on 1 September 1939? Later?

While more can always be said, I've previously written about the origins of the terminology of the war here, which also has links to a few previous answers on the topic.
