. Originally known as Decoration Day, it began after the Civil War as a time when communities decorated the graves of fallen soldiers with flowers, wreaths, and flags
. The first national observance took place on May 30, 1868, when General John A. Logan proclaimed it as Decoration Day, and ceremonies were held at Arlington National Cemetery
. Over time, Memorial Day expanded to honor all American military personnel who died in any war, not just the Civil War
. Traditionally, people visit cemeteries and memorials to mourn the fallen, placing American flags on graves and laying flowers. A national moment of remembrance occurs at 3 p.m. local time
. The day also marks the unofficial start of summer in the U.S., often celebrated with picnics and outdoor activities, although its primary significance remains solemn remembrance
. Memorial Day differs from Veterans Day, which honors all military veterans, living and deceased, while Memorial Day specifically honors those who died in service
