When is Armed Forces Day?

An Armed Forces Day, alongside its branch-specific variants often referred to as Army or Soldier's Day, Navy or Sailor's Day, and Air Force or Aviator's Day, is a holiday dedicated to honoring the armed forces, or one of their branches, of a sovereign state, including their personnel, history, achievements, and sacrifices. It's often patriotic or nationalistic in nature, carrying information value outside of the conventional boundaries of a military's subculture and into the wider civilian society. Many nations around the world observe this day. It is usually distinct from a Veterans or Memorial Day, as the former is dedicated to those who previously served and the latter is dedicated to those who perished in the fulfillment of their duties.
