National Pearl Harbor Remembrance Day, an annual commemoration of the 1941 attack, will be observed Monday, Dec. 7.
Postal Service facilities are required to fly the U.S. flag at half-staff this day.
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.
