After World War II and the Korean War, the U.S. Congress changed Armistice Day to Veteran's Day in 1954. The new designation honors all American war veterans. The day was observed on Nov. 11 each year until 1971 when Congress made the observance a movable holiday so that employees could celebrate with a three-day weekend. Veteran's Day moved back to Nov. 11 in 1978. As of 2014, the federal government observes the holiday on a Friday or Monday only if Nov. 11 falls on the weekend.
