What is the date known as D-Day?

D-Day refers specifically to June 6, 1944, a pivotal date during World War II when Allied forces launched a large-scale invasion of Nazi-occupied France at Normandy. This operation, known as Operation Overlord, marked the beginning of the liberation of Western Europe from Nazi control. The massive amphibious assault involved thousands of troops from various Allied nations, extensive planning, and significant logistical efforts, making it one of the most significant military operations in history.

The other dates listed do not align with the term D-Day in this historical context. December 7, 1941, relates to the attack on Pearl Harbor which propelled the United States into World War II. August 6, 1945, marks the day the atomic bomb was dropped on Hiroshima, while September 2, 1945, is the date Japan formally surrendered, marking the end of the war. Each of these events is significant in its own right, but June 6, 1944, specifically embodies the term D-Day in the context of Allied military operations during World War II.
