It is the universal custom to display the flag only from sunrise to sunset on buildings and on stationary flagstaffs in the
open. However when a patriotic effect is desired, the flag may be displayed 24 hours a day if properly illuminated during
the hours of darkness.
When displayed either horizontally or vertically against a wall, the union (blue star field)
should be uppermost and to the left of the observer - that is, to the own right of the flag. When
displayed in a window, the flag should be displayed in the same way, with the union to the left of the observer in the street.
No other flag or pennant should be placed above or, if on the same level, to the right of the flag
of the United States of America, except during church services conducted by naval chaplains at sea -
for personnel of the Navy - when the church pennant may be flown above the flag.
No person shall display the flag of the United Nations or any other national or international
flag equal, above, or in a position of superior prominence or honor to, or in place of, the flag
of the United States at any place within the United States of any territory or possession thereof,
heretofore followed of displaying the flag of the United Nations in a position of superior
prominence or honor, and other national flags in positions of equal prominence or honor, with
that of the flag of the United States at the headquarters of the United Nations.
When flags states, cities or localities, or pennants of societies are flown on the
same halyard with the flag of the United States, the latter should always be at the peak.
When the flags are flown from adjacent staffs, the flag of the United States should be
hoisted first and lowered last. No such flag or pennant may be placed above the flag of the
United States or to the United States flags right.
The flag of the United States of America, when it is displayed with another flag against
a wall from crossed staffs, should be on the right, the flags own right, and its staff should be
in front of the staff of the other flag.
The flag of the United States of America should be at the center and at the highest point
of the group when a number of flags of States or Localities or pennants of societies are grouped
and displayed from staffs.
When flags of two or more nations are displayed, they are to be flown from separate staffs of the
same height. The flags should be of approximately equal size. International usage forbids the
display of the flag of one nation above that of another nation in the time of peace.
