A D-Day timeline cannot only take into account the events of June 6, 1944. The wider events of the war must be included to give context to the largest military operations of the Allied war effort. This article only touches on the events surrounding the two months before and after the Invasion of Normandy and does not take into account the massive planning efforts that extended back multiple months.
