The National Aviation Day, celebrated on the 19th day of August, is a United States national observation that celebrates the development of human flight.  The aforementioned holiday was established by a presidential proclamation in 1939, which designated the anniversary of Orville Wright’s birthday to be National Aviation Day.

The President may issue each year a proclamation

• designating August 19 as National Aviation Day;
• calling on United States Government officials to display the flag of the United States on all Government buildings on National Aviation Day; and
• inviting the people of the United States to observe National Aviation Day with appropriate exercises to further stimulate interest in aviation in the United States.
