On May 21, President Trump ordered U.S. flags flown at half-staff to honor the victims of the coronavirus pandemic.

Flags should be flown at half-staff until sunset Sunday, May 24.

Additionally, there are flag requirements for Memorial Day, which is Monday, May 25.

Postal Service 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 prior to the holiday. Return the flag to full staff when the facility opens Tuesday, May 26.

For more information, refer to the Postal Service’s guidelines for U.S. flag display and maintenance, as well as requirements for displaying the POW-MIA flag.
