The meaning behind the "D" in D-Day has to do with military terminology.
On the morning of June 6, 1944, Allied forces staged an enormous assault on German positions on the beaches of Normandy, France. The invasion is often known by the famous nickname “D-Day,” yet few people know the origin of the term or what, if anything, the “D” stood for. Most argue it was merely a redundancy that also meant “day,” but others have proposed everything from “departure” to “decision” to “doomsday.”
According to the U.S. military, “D-Day” was an Army designation used to indicate the start date for specific field operations. In this case, the “D” in D-Day doesn’t actually stand for anything—it’s merely an alliterative placeholder used to designate a particular day on the calendar.
The military also employed the term “H-Hour” to refer to the time on D-Day when the action would begin. This shorthand helped prevent actual mission dates from falling into enemy hands, but it also proved handy when the start date for an attack was still undecided. Military planners also used a system of pluses and minuses to designate any time or day occurring before or after D-Day or H-Hour.
For example, D+2 meant two days after D-Day, while H-1 referred to one hour before H-Hour. These terms allowed units to effectively coordinate their operations ahead of time even when they didn’t know their actual start date, and they also provided flexibility in the event that the launch day shifted.
Use of these terms stretches back to World War I. One American field order from September 1918 noted, “The First Army will attack at H-Hour on D-Day with the object of forcing the evacuation of the St. Mihiel salient.” Other nations had their own shorthand. In World War I, the French used the code date “le Jour J,” while the British called their operation start days “Z-Day” and “Zero Hour.”
That’s a really hostile comment ...
Lots of D-Days in the Pacific Theater during the War.
As a kid my neighbor was at D-Day. He said it stood for “Disembarkment” Day.
I believe that October 20, 1944, the day when MacArthur returned to the Philippines, was called “A Day” for the same reason.
And on June 15 of that same year, the landing on Saipan.
Also on June 15, the Imperial Japanese Navy counter attack. The Battle of the Philippine Sea, aka The Great Marianas Turkey Shoot.
Dwight D. Eisenhower: What counts is not necessarily the size of the dog in the fight -- it's the size of the fight in the dog.
I always thought if meant Decision-Day. I stand corrected, thanks for the post.
Exactly, because lot of amphibious landings were made. In the Mediterranean, there was a D-Day in n Africa, another one for Sicily, then for Italy, and after 6/6/44, there was a D-Day in the s of France.
I was always told the D in D-Day stood for Debarkation...The exact date of the invasion not being known other than a projected window of dates in late May thru June 1944...
Due to vaguery of weather and tide, phases of moon, etc, the D was a target not an actual set date...
