WW2 was a global conflict that raged from September 1939 to August 1945; almost six long years.
The change of seasons brought with it changes in the pace of the war. Spring generally meant new offensives, while winter could mean stalemate or a winter offensive - such as those made by the Russians on the eastern front, or the Germans during the Battle of the Bulge in the Ardenne.
