President Joe Biden has ordered U.S. flags flown at half-staff to honor the victims of the April 2 attack on the U.S. Capitol.
Flags should be flown at half-staff until Tuesday, April 6, at sunset.
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.
The USPS Administrative Support Manual has additional guidelines on U.S. flag display and maintenance.
