The United States Congress passed a resolution authorizing National POW/MIA Recognition Day to be observed on July 18, 1979. It was observed on the same date in 1980 and was held on July 17 in 1981 and 1982. It was then observed on April 9 in 1983 and July 20 in 1984. The event was observed on July 19 in 1985, and then from 1986 onwards the date moved to the third Friday of September. The United States president each year proclaims National POW/MIA Recognition Day. Many states in the USA also proclaim POW/MIA Recognition Day together with the national effort.
