On Memorial Day, the President of the United States participates in a ceremony at Arlington National Cemetery, where he lays a wreath at the Tomb of the Unknown Soldier. This solemn event honors the men and women who have died in military service to the country. The ceremony typically includes a moment of silence, speeches, and the playing of "Taps" to commemorate the sacrifices made by fallen service members.
Memorial Day always takes place on the last Monday of May.
