The term "D-Day" is a military term that refers to the day on which a specific operation or event is to take place. The "D" does not stand for anything in particular, but rather serves as a placeholder for the day on which the operation is scheduled. Similarly, "H-Hour" is used to designate the time that the operation is to begin.

The invasion of Normandy, also known as the Battle of Normandy or D-Day, was one of the most significant events of World War II. It involved the landing of over 150,000 Allied troops on five beaches along the Normandy coast, supported by airborne landings and naval bombardments. The operation was a critical step in the Allies' campaign to defeat Nazi Germany and bring an end to the war in Europe.
