When to Display the Flag
The flag should be displayed on all days when weather permits, especially on legal holidays or other special occasions. It is customary to display the flag from sunrise to sunset on buildings or on stationary flagstaffs in the open. However, on special occasions it may be displayed at night, preferably lighted. In several places the flag flies day and night; among these are the Capitol in Washington, D.C., and the Fort Henry National Monument in Baltimore, which was the inspiration for “The Star Spangled Banner" by Francis Scott Key.
The flag should be displayed…
• on or near the main administration building of every public institution
• in or near polling places on election days
• in or near schools when they are in session
A citizen may fly the flag on any day he wishes.
