President Trump has ordered U.S. flags flown at half-staff to honor the victims of the recent mass shootings in El Paso, TX, and Dayton, OH.

Flags should be flown at half-staff until sunset Thursday, Aug. 8.

To fly the flag at half-staff, hoist the flag to the peak for an instant and then lower it to the half-staff position. The flag should be raised to the peak again before it’s lowered for the day.

For additional information, refer to the Postal Service’s Administrative Support Manual, which explains the organization’s guidelines on U.S. flag display and maintenance.
