Memorial Day, which is observed on the last Monday of May, commemorates the men and women who died while in the military service. In observance of the holiday, many people visit cemeteries and memorials, and volunteers often place American flags on each grave site at national cemeteries. A national moment of remembrance takes place at 3:00 p.m. local time.

Many veterans are buried abroad, near where they died during battle. Pictured is an American cemetery in Impruneta, Italy.
