Does the D in D-Day stand for Dover?
I wondered the same thing about what D-Day stood for until I talked to my day about his WWII experience for a class that I had. He talked about his units D-Day in North Africa. It was the departure day for an operation. Normandy is just the most famous ‘D-Day’, so people just use that term to refer to most recognized and well known D-day at Normandy.
