Memorial Day is a U.S. federal holiday observed on the last Monday in May. It is a day dedicated to honoring and remembering the military personnel who have died while serving in the United States Armed Forces. The holiday was originally known as Decoration Day, a tradition that began after the Civil War involving decorating the graves of fallen soldiers with flowers, wreaths, and flags. Memorial Day is both a celebration and a solemn reflection on the sacrifice made by service members who gave their lives in defense of the country. It is a time for visiting cemeteries and memorials, placing flags on graves, and participating in ceremonies to pay respects to the fallen. The day also serves to remind Americans of the high price of freedom and the debt of gratitude owed to those who made the ultimate sacrifice. While Memorial Day honors those who died in service, it is distinct from Veterans Day, which celebrates all who have served in the U.S. military, living or deceased. The tradition dates back to May 30, 1868, when the first widely recognized observance was held to honor Union soldiers who died in the Civil War. Over time, Memorial Day expanded to commemorate all fallen American military personnel from all wars. In summary, Memorial Day is for honoring and remembering the men and women who died while serving in the U.S. military, reflecting on their sacrifice, and showing gratitude for their service and the freedoms it protected. It is a solemn day of remembrance and national respect.
