D-Day is a term used in the military to mean the actual day a major operation or event is to begin. The days leading up to a D-Day are called D-1, D-2, D-3, and so on. The days after a D-Day are D+1, D+2, D+3, and so on.
There were many days in military history that were called D-Day. The most famous D-Day was June 6, 1944 when the biggest amphibious (from the sea to the land) attack in military history took place in Normandy during World War II. This attack was codenamed Operation Overlord,led by American General Dwight Eisenhower. The Allies (Britain, Canada, and America) attacked Europe occupied by Nazi Germany. It was very important for the Allied success in World War II, though over 3,500 men were lost while attacking the beaches. About two months later, after very hard fighting, the Allies won World War II. They freed France from the Germans. Less than one year later Germany surrendered, and the Allies freed France from the Germans.

Personally, one of my favorite movies is Saving Private Ryan. Seen it at least 10 times. After time #3 or so, I simply cannot watch the first 20 minutes of that film anymore. It no doubt captures (as well as a film can) the horror those men went through early in that operation. Hard to imagine how so many of the early ones on those beaches survived at all.
My former father-in-law was one. He was in the army and on one of the landing craft boats in the first wave. His boat sunk a quarter mile out but he was picked up more than an hour in the water. Many of those men drowned, but he survived and went into the beach later in the afternoon when the worst was over. He went on to survive the war and come home to marry and have 7 kids. Died at 93 two years ago, yes the greatest gen...
