We used both terms, the WW term meant the overall event and the other one was for the Soviet part that started June 22, 1941 and ended in 1945, first in Germany, the main victory, the in Far East in the war with Japan. The term itself is taken from to the war of 1812 with Napoleon; that one was The Patriotic War. The Finnish war has its own name. The Poland operation is not counted as a part of the war.
