What does the “D” in D-Day stand for?

The “D” does not stand for “deliverance,” “doom,” “debarkation,” or similar words. In fact, it stands for nothing. The “D” is derived from the word “Day”. “D-Day” denotes the day on which a military operation begins. The term “D-Day” has been used to refer to many different operations, but it is now generally used only to refer to the Allied landings in Normandy on June 6, 1944.

When a military operation is planned, the exact date and time are not always known. The term “D-Day” was therefore used to denote the date when operations would begin, whenever that should be. The day before D-Day was known as “D-1”, while the day after D-Day was “D+1”, and so on. This meant that if the prognosticated date of an operation was changed, not all dates in the plan had to be changed as well. This actually happened in the case of the Normandy landings. D-Day in Normandy was originally scheduled to take place on June 5, 1944, but was postponed to the following day at the last minute due to bad weather. The armed forces also used the phrase “H hour” for the time of day when operations were to begin.
