Veterans Day is a U.S. public holiday designated to honor military veterans, defined as individuals who have previously served in the United States Armed Forces. The observance specifically recognizes living former service members for their patriotism, service, and sacrifice. It is distinct from Armed Forces Day, which honors those currently serving in the military, and from Memorial Day, which commemorates personnel who died while in service.
The term "veteran" is formally defined under U.S. law. According to Title 38 of the Code of Federal Regulations, a veteran is a person who served in the active military, naval, or air service and was discharged or released under conditions other than dishonorable. The holiday originated as Armistice Day in 1919 to mark the end of World War I and honor its veterans. In 1954, after World War II and the Korean War, Congress amended the act by replacing "Armistice" with "Veterans" to formally recognize veterans of all U.S. wars and periods of service.
Consequently, the holiday's application is to thank and honor all living individuals who have honorably served in the U.S. military, whether in wartime or peacetime. This specific focus distinguishes its purpose from other national observances and acknowledges the contributions of those who have completed their service and returned to civilian life. The day honors the individuals who are former members of the military institution, not the active-duty force itself.
