MEMORIAL DAY, observed on the last Monday of May, honors the brave men and women who have died while serving in the U.S. military. Originally known as Decoration Day, this national holiday began after the Civil War to commemorate fallen Union soldiers. Today, Memorial Day serves as a solemn day of remembrance for all American service members who have sacrificed their lives for our freedom and country. The holiday is traditionally marked by ceremonies at cemeteries and memorials, and it also signifies the unofficial start of summer, with many families gathering for barbecues and picnics. Common Memorial Day observances include displaying American flags, wearing red poppies, and participating in parades that honor the sacrifices of our military heroes.
