Armed Forces Day takes place on May 16, 2020. Armed Forces Day is celebrated on the third Saturday in May. It falls near the end of Armed Forces Week, which begins on the second Saturday of May and ends on the third Sunday of May. First observed on 20 May 1950, the day was created on 31 August 1949, to honor Americans serving in the five U.S. military branches following the consolidation of the military services in the U.S. Department of Defense.
The first Armed Forces Day was celebrated by parades, open houses, receptions and air shows. In 1962, President John F. Kennedy established Armed Forces Day as an official holiday. The United States' longest running city-sponsored Armed Forces Day Parade is held in Bremerton, Washington. Because of their unique training schedules, National Guard and Reserve units may celebrate Armed Forces Day/Week over any period in the month of May. (With material from: Wikipedia)
