Rules for the proper display of the U.S. Flag were finalized and became public law on December 22, 1942. When displaying the American flag at home, it is important to know the rules for proper display put forth by the United States of America. A complete copy of the US Flag Code can be found HERE.
1. Display on buildings and stationary flagstaffs in open; night display: 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.
2. The flag should be hoisted briskly and lowered ceremoniously.
3. The flag should not be displayed on days when the weather is inclement, except when an all weather flag is displayed.
4. 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, when the church pennant may be flown above the flag during church services for the personnel of the Navy. 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 or any Territory or possession thereof: Provided, That nothing in this 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, 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.
5. When flags of 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 flag’s right.
6. 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 time of peace.
7. When the flag of the United States is displayed from a staff projecting horizontally or at an angle from the window sill, balcony, or front of a building, the union of the flag should be placed at the peak of the staff unless the flag is at half staff. When the flag is suspended over a sidewalk from a rope extending from a house to a pole at the edge of the sidewalk, the flag should be hoisted out, union first, from the building.
8. The flag should never touch anything beneath it, such as the ground, the floor, water, or merchandise.
9. The flag should be displayed on all days, especially on New Year’s Day, January 1; Inauguration Day, January 20; Lincoln’s Birthday, February 12; Washington’s Birthday, third Monday in February; Easter Sunday (variable); Mother’s Day, second Sunday in May; Armed Forces Day, third Saturday in May; Memorial Day (half-staff until noon), the last Monday in May; Flag Day, June 14; Independence Day, July 4; Labor Day, first Monday in September; Constitution Day, September 17; Columbus Day, second Monday in October; Navy Day, October 27; Veterans Day, November 11; Thanksgiving Day, fourth Thursday in November; Christmas Day, December 25; and such other days as may be proclaimed by the President of the United States; the birthdays of States (date of admission); and on State holidays.
