D-Day is observed in France every June 6 to commemorate the Normandy Landing of the Allied Expeditionary Forces during World War II. This significant event marks the largest amphibious invasion in history, which took place on June 6, 1944, when approximately 160,000 allied troops crossed the English Channel. The day is marked by various local and federal events, including laying wreaths at monuments dedicated to paratroopers and organizing meetings with war veterans. Notably, the 70th anniversary commemoration in 2014 featured representatives from 18 countries, including the USA, Germany, Great Britain, and Russia, with Queen Elizabeth II leading the memorial service. These activities reflect the importance of D-Day in honoring the sacrifices made during the war and its lasting impact on history.
