Every Memorial Day, Americans unite to honor members of the United States Armed Forces who lost their lives defending our freedom. Celebrated on the last Monday in May, Memorial Day was originally called Decoration Day during Civil War times; the holiday officially became “Memorial Day” in 1967. There are many American traditions of celebrating Memorial Day, which often include a town parade or vigil to commemorate fallen soldiers. The flag of the United States is also flown at half-staff until noon, then raised to the top again for the rest of the day. Explore Hallmark today for Memorial Day Cards and Products.
