The Normandy Landings were the landing operations of the Allied invasion of Normandy, also known as Operation Neptune and Operation Overlord, during World War II. The landings commenced on Tuesday, 6 June 1944 (D-Day), beginning at 6:30 AM British Double Summer Time (UTC+2). In planning, D-Day was the term used for the day of actual landing, which was dependent on final approval. The assault was conducted in two phases: an air assault landing of 24,000 American, British, Canadian and Free French airborne troops shortly after midnight, and an amphibious landing of Allied infantry and armoured divisions on the coast of France commencing at 6:30 AM. There were also subsidiary 'attacks' mounted under the codenames Operation Glimmer and Operation Taxable to distract the German forces from the real landing areas.[
