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 twenty-four hours a day if properly illuminated
during the hours of darkness.
The flag should be hoisted briskly and lowered ceremoniously.
The flag should not be displayed on days when the weather is
inclement, except when an all-weather flag is displayed.
The flag should be displayed daily, on or near the main administration
building of every public institution, in or near every polling
place on election day, during school days in or near every schoolhouse.
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 fag 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 or
any Territory or possession thereof: Provided, that nothing
in the section shall make unlawful - the continuance of the
practice heretofore followed of displaying the flag of the United
Nations in a position of superior prominence or honor, with
that of the flag of the United States at the headquarters of
the United Nations.
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 flag's 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 Sates or localities or pennants of societies are grouped
and displayed from staffs.
When flags of States, cities, or localities, or pennants of
societies are flown on the same halyard with the flag of the
Uninted states, the U.S. Flag should always be at the peak.
When the flags are flown from adjacent staff, 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 flag's right.

When flags of two or more nations are displayed, they are
to be flown from separate staffs of the same heights. 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 time of peace.
