Armed Forces Day is marked annually on the third Saturday of May. President Harry S. Truman started commemorating this day to honor and pay tribute to military heroes for their service to the United States of America.

This year, the Armed Forces Day is marked on May 15.

"Armed Forces Day, Saturday, May 20, 1950, marks the first combined demonstration by America's defense team of its progress, under the National Security Act, toward the goal of readiness for any eventuality. It is the first parade of preparedness by the unified forces of our land, sea, and air defense," Truman stated in an excerpt of the Presidential Proclamation of Feb. 27, 1950.
