The Normandy landings, also known as Operation Neptune were the landing operations of the Allied invasion of Normandy, inOperation Overlord, during World War II. The landings commenced on Tuesday, 6 June 1944 (D-Day), beginning at 6:30 AMBritish Double Summer Time (GMT+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 airborne assault landing of 24,000 British, American, Canadian and Free Frenchairborne 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 decoy operations mounted under the codenames Operation Glimmer and Operation Taxable to distract the German forces from the real landing areas.
The operation was the largest amphibious invasion in world history, with over 160,000 troops landing on 6 June 1944. 195,700Allied naval and merchant navy personnel in over 5,000 ships were involved. The invasion required the transport of soldiers and material from the United Kingdom by troop-laden aircraft and ships, the assault landings, air support, naval interdiction of theEnglish Channel and naval fire-support. The landings took place along a 50-mile (80 km) stretch of the Normandy coast divided into five sectors: Utah, Omaha, Gold, Juno and Sword.

D-Day is a term often used in military parlance to denote the day on which a combat attack or operation is to be initiated. "D-Day" often represents a variable, designating the day upon which some significant event will occur or has occurred; see Military designation of days and hours for similar terms. The initial D in D-Day has had various meanings in the past, while more recently it has obtained the connotation of "Day" itself, thereby creating the phrase "Day-Day", or "Day of Days". On the same principle, the equivalent terms in French, Basque, Romanian and Slovenian are Jour J, E eguna, Ziua-Z, and Dan D.
The best known D-Day is June 6, 1944 — the day of the Normandy landings — initiating the Western Allied effort to liberate mainland Europe from Nazi occupation during World War II. However, many other invasions and operations had a designated D-Day, both before and after that operation.
The terms D-Day and H-Hour are used for the day and hour on which a combat attack or operation is to be initiated. They designate the day and hour of the operation when the day and hour have not yet been determined, or where secrecy is essential. For a given operation, the same D-Day and H-Hour apply for all units participating in it.
When used in combination with numbers, and plus or minus signs, these terms indicate the point of time preceding or following a specific action. Thus, H−3 means 3 hours before H-Hour, and D+3 means 3 days after D-Day. (By extension, H+75 minutes is used for H-Hour plus 1 hour and 15 minutes.)
Planning papers for large-scale operations are made up in detail long before specific dates are set. Thus, orders are issued for the various steps to be carried out on the D-Day or H-Hour minus or plus a certain number of days, hours, or minutes. At the appropriate time, a subsequent order is issued that states the actual day and times.
In spacecraft launchings, NASA utilizes the term 'T-Time' for the timing of the launch sequence down to the second (rather than M-Minute and S-Second), as in the expression "T minus 10 seconds and counting" for their countdown clock.
When referencing a local time zone, "Zulu" refers to Universal Co-ordinated Time (formerly Greenwich Mean Time). For other zones see list of military time zones.
