Memorial Day, formally known as Decoration Day is a day of remembrance to honor all Americans who died while in the military service.
This holiday originated after the Civil war to commemorate the Union and Confederate soldiers but was extended to honor all American soldiers by the 20th century.
Memorial Day is observed every year on the last Monday of May. It typically marks the start of summer, with Labor Day at the start of September marking its end.
Americans honor fallen soldiers on Memorial Day by visiting cemeteries and placing flags and flowers on graves, visiting memorials and wearing red poppies.
