It should be displayed vertically, whether indoors or out, and suspended so that its folds fall free as though the flag were staffed. The stripes may be displayed either horizontally or vertically against a wall, the union should be uppermost and to the flag's own right; that is, to the observer's left. When displayed in a window of a home or a place of business, the flag should be displayed in the same way; that is, with the union or blue field to the left of the observer in the street. (Ref Flag Code 7(i))
When to display at Half-Staff.
This gesture is a sign to indicate the nation mourns the death of an individual(s), such as death of the President or former President, Vice President, Supreme Court Justice, member of Congress, Secretary of an executive or military department, etc. Only the President of the United States or the Governor of the State may order the flag to be half-staffed. (ref: Flag Code 7(m))
When used on a speaker's platform, the flag, if displayed flat, should be displayed above and behind the speaker. When displayed from a staff in a church, public auditorium or meeting place, the flag should hold the position of superior prominence, in advance of the audience, and in the position of honor at the clergyman's or speaker's right as he faces the audience. Prior to the Flag Code changes in 1976, the display procedure was somewhat different. Now the staffed flag should always be placed to the right of the speaker (observer's left) without regard to a platform or floor level. (ref: Flag Code 7 (k))
The Flag Code states it is the universal custom to display the flag only from sunrise to sunset on buildings and on stationary flag staffs in the open. However, when a patriotic effect is desired, the flag may be displayed twenty-four hours a day if properly illuminated during the hours of darkness. (ref: Flag Code 6(a)) The American Legion interprets "proper illumination" as a light specifically placed to illuminate the flag (preferred) or having a light source sufficient to illuminate the flag so it is recognizable as such by the casual observer.
