The flag is put back to full staff at the end of the designated half-staff period, typically specified in an official proclamation by the President or a state governor. For example:

• On Memorial Day, the flag is flown at half-staff from sunrise until noon only, then raised briskly to full staff until sunset.
• After the death of a President, the flag is flown at half-staff for 30 days, then returned to full staff.
• For a Vice President, Chief Justice, or Speaker of the House, it is typically 10 days at half-staff.
• For other officials, the half-staff duration may last until burial or a specified period.

The flag should be raised briskly to full staff at the end of the mourning period as a symbol of resilience and respect. This transition normally happens at the exact time stated in the proclamation or on the designated day (e.g., noon on Memorial Day).
