Gettysburg National Cemetery
Memorial Day or Decoration Day is a federal holiday in the United States for remembering the people who died while serving in the United States Armed Forces. The holiday is currently observed every year on the last Monday of May.
Many people visit cemeteries and memorials on Memorial Day, particularly to honor those who died in military service. Many volunteers place an American flag on each grave in national cemeteries.
Two other days celebrate those who serve or have served in the U.S. military: Veterans Day, which celebrates the service of all U.S. military veterans; and Armed Forces Day, a minor U.S. remembrance celebrated earlier in May, specifically honoring those currently serving in the U.S. military.
