Dear friends,

What does D stand for? ( I suppose it's for Dooms Day ).
What does D-Day refer to? ( I suppose it refers to the first day of important events like exam,etc)
How and when should it be used?

Thanks in advance,

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".[1]By far, the best known D-Day is June 6, 1944 — the day on which the Invasion of Normandy began — commencing 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.[2]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. There is but one D-Day and one H-Hour for all units participating in a given operation.When used in combination with figures,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. H+75 minutes means 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.


Is the above passage copied from somewhere? If so, it would be good to acknowledge the source.

My grand father told me that this is the story of why it was called D -Day:

Churchill, Roosevelt and De Gaul were sitting around trying to think of a good name for such an important day ..

"I know", said Roosevelt, "let's call it A- Day ..
"Non", said De Gaul," Aidez means help .. that is not a good name."

" Then what about B-Day?", said Roosevelt.
" Non", said De Gaul," Bidet, you must be joking".

"then we can call it C-Day", said Churchill ..
"Cedez .. give up? Jamais!"

... so they called it D - Day ...

D Day is military parlance for Day of Days, the exact day when something will happen; for example, the Normany Invasion during World War II. The French call it Le Jour of J. The military also uses H Hour for Hour of Hours. The D in D Day does not stand for anything else such as debarkation although many people who have never checked its origin think so,

Well if you want to be technical about it, no body is 100% sure, it is said to have many meanings such as designation, doomdays or I have even seen references to death day. But blacksnake statement is accurate however the D in this case is mostly accepted as literally meaning Day, so D-day means Day - Day, just the day the operation was to begin, but it is also widely accepted as designation day as well as said in:
'D-Day, The Greatest Invasion - A peoples History'
Furthermore it explains that D+7 literally means Day + 7, Designation day + 7 or 7 days after the designated landing date.
A good reference to this is a report in Times Magazine on June 12 1944 stating that "as far as the U.S. Army can determine, the first use of D for Day, H for Hour was in Field Order No.8, of the First Army, A.E.F., issued on September 20, 1918 which read, ' The first Army will attack at H-hour on D-Day with the object of forcing the evacuation of the St.Mihiel salient." (p.491)www.nationalww2museum.org
Brigadier General Schultz reminds us that the Invasion of Normandy on the 6th of June 1944 was not the only D-day of ww2. Every Amphibious assualt including those of the Pacfic,, Nth Africa, and in Sicily and Italy - had it's own D-day.
D-day is simply an alteration of H-Hour
Hii friends,

This is the day(June 6, 1944) on which Allied forces invaded france during World War II.
Here 'D' stands for decisive or dooms Day, means 'Day of the Last Judgment'.
So wht u all think about it???

I think the prior two and half pages make more sense to me than "Doomsday."

I agree with GG. It has nothing to do with Revelation's prediction of the end of the world.
