Answer 2

It doesn't really stand for anything. It just means, the day on which the military operation will begin. It's been used for many different missions but is generally only referred to as the Allied landings in Normandy on June 6, 1944.

It's standard military parlance to refer to planned operations in this way: D stands for the date of the event, and H is the planned time. The operation commences on D day, at H hour. Some things may be scheduled to occur (for example) by D-2, or two days before the event itself. If something that absolutely must happen by D-2 is delayed, whenever it occurs is still D-2, the date of the event is just changed to be two days from then.

It's similar to a NASA rocket launch. The actual time of launch is not known until it happens, so it's simply called T. "T minus 5 minutes" means "we plan to launch in five minutes, unless something goes wrong." If problems do arise, they simply stop the count ("T minus two minutes and holding", meaning "we're waiting on something, and we're ready to launch two minutes from whenever whatever it is we're waiting on happens.") Even after the launch, T is still used, since it makes more sense to think in terms of "the first burn is scheduled to stop 90 seconds after launch" ... at T plus 90 seconds ... than to try to do the actual math in your head ("Let's see, launch was at 1:17:05 PM EST, so the burn stops at 1:17:95... which is, let me think, 1:19:05... no wait, 1:18:35, shoot, I should have stopped it twenty seconds ago.")

For similar reasons, D is used to represent the start in military operations. That way if its delayed, you don't need to change all the unit orders to reflect the new actual date, they simply know "we have to be at objective A by two days from when we landed". If you had listed it in the orders as "June 8", then if the landing didn't take place until June 11, you'd have mass confusion as unit commanders tried to work out whether their orders referred to the new, revised schedule, or the old one.

Answer 3

D just stands for Day

Similarly in the phrase "H hour on D day" H stands for hour.

Answer 4

It really stands for nothing. It is just a day that a specified military activity is to take place. But some do say it just stands for day.

Answer 5

The D means nothing.

I always thought that D-day was short for decision day or something similar, but according to dictionary.reference.com, the D is just short for "day".

Answer 6

It doesn't have an official meaning. Some people think it means different things. Currently, it is commonly meant as "Day". So D-Day means Day-Day.

Answer 7

d stands for love peace and happyness
