When did WWII end exactly?

As I was researching, I found that there has been a lot of contradiction as to when WWII ended exactly. I know there was V-E Day and V-J Day, but when was the official end of WWII? Was it when the German's surrendered or when the Japanese surrendered or when an armistice was signed? Thanks for all your help! :) show more As I was researching, I found that there has been a lot of contradiction as to when WWII ended exactly.
