Memorial Day or Decoration Day is a federal holiday in the United States for remembering the people who died while serving in the country's armed forces. The holiday, which is currently observed every year on the last Monday of May, was held on May 28, 2018. The holiday was held on May 30 from 1868 to 1970. It marks the unofficial start of the summer vacation season, while Labor Day marks its end.
Many people visit cemeteries and memorials, particularly to honor those who have 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.
