Memorial Day, a federal holiday to remember the men and women who died while serving in the armed forces, is Monday, May 27.
Facilities that are open on the holiday must fly the U.S. flag at half-staff.
The U.S. flag must be flown at half-staff from sunrise — or the hour when it’s raised — until noon. Then, hoist the flag to the peak of the staff, where it either must fly until the time of closing or no later than sunset (unless the flag is lighted).
When the U.S. flag is flown at half-staff, all other flags must fly at half-staff, too.
Facilities that fly the flag at all times and are closed Memorial Day should lower the flag to half-staff when the facility closes before the holiday. Return the flag to full staff when the facility re-opens Tuesday, May 28.
The USPS® Administrative Support Manual has guidelines for U.S. flag display and maintenance (see blue.usps.gov/cpim/ftp/manuals/asm/html/asmc4_019.htm).
