Purple Heart Day is marked annually on Aug. 7 to commemorate the creation of the U.S. military's oldest decoration for meritorious service.

On this day, Americans remember the brave men and women who were either wounded on the battlefield or have sacrificed their lives fighting for the country.

The day is also known as National Purple Heart Day, Purple Heart Recognition Day and Purple Heart Appreciation Day. It was first observed in 2014, according to National Today. The original Purple Heart, which is designated as the Badge of Military Merit, was established by George Washington in 1782.
