What people think that world war 2 started in 1938 and some other people believe that it began in 1939 most people know that it ended in 1945 you think what year did the war start and what exact date?

Actually, World War 2 started in 1939 and ended in 1945 ( as you already know.). We don't have the exact dates, but I'm sure an encyclopedia would serve you better than I could! Ha Ha! I guess that isn't really funny but oh well! World war 2 started on the Friday 1st of September 1939 in Poland with German troops stormed their frontier. It was fully underway with Europe starting war on Germany.it finally ended 6 years later on the 8th May 1945 after Hitler committed suicide and Germany surrendered.
