"d" day today.

" D" just stands for the Day (eg the day of some significant event). The same question was asked in the media here yesterday.

When a military operation is being planned, its actual date and time is not always known exactly. The term "D-Day" was therefore used to mean the date on which operations would begin, whenever that was to 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 projected date of an operation changed, all the dates in the plan did not also need to be changed. This actually happened in the case of the Normandy Landings. D-Day in Normandy was originally intended to be on 5 June 1944, but at the last minute bad weather delayed it until the following day. The armed forces also used the expression "H-Hour" for the time during the day at which operations were to begin.
