Defence Day or Army Day (Pakistan)

Defence Day is celebrated in Pakistan as a national day to commemorate the sacrifices made by Pakistani soldiers in defending its borders. The date of 6 September marks the day in 1965 when Indian troops crossed the international border to launch an attack on Pakistani Punjab in a riposte to Pakistan's Operation Grand Slam targeting Jammu. While it is officially commemorated as an unprovoked surprise attack by India, repulsed by the Pakistan Army despite its smaller size and fewer armaments, the narrative has been criticised by Pakistani commentators as representing false history.

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.
