As we celebrate our nation's Independence a lot of people will be displaying the American flag. This is always a good time to take a look at some very important flag etiquette tips and practices. According to Military.com

When placed on a single staff or lanyard, place the U.S. Flag above all other flags.

 

When flags are displayed in a row, the U.S. flag goes to the observer’s left. Flags of other nations are flown at same height. State and local flags are traditionally flown lower.

 

When used during a marching ceremony or parade with other flags, the U.S. Flag will be to the observer’s left.

 

Display the U.S. flag from sunrise to sunset on buildings and stationary flagstaffs in the open. When a patriotic effect is desired the flag may be displayed 24-hours a day if properly illuminated during the hours of darkness.

 

When the flag is displayed over the middle of the street, it should be suspended vertically with the union (blue field of stars) to the north in an east and west street or to the east in a north and south street.

 

When placed on a Podium the flag should be placed on the speaker’s right or the staging area. Other flags should be placed to the left.

 

When displayed either horizontally or vertically against a wall (or other flat surface), the union (blue field of stars) should be uppermost and to the flag's own right, that is, to the observer's left.

 

When displayed in a window it should be displayed in the same way -- with the union or blue field to the left of the observer in the street.
