This tradition was established by federal law — specifically codified in the Flag Code and formalized through presidential proclamation. The practice dates back to a 1950 proclamation and has been reaffirmed by presidents since.
The reason it returns to full-staff at noon is equally meaningful: the second half of the day, from noon until sunset, the flag flies at full-staff to symbolize the living nation honoring and celebrating the sacrifice of those who died. It's a transition from mourning to tribute — acknowledging both grief and national pride.
So the two parts of the day carry distinct symbolic weight:
Sunrise to noon — a period of national mourning and remembrance for the fallen
Noon to sunset — a salute to the nation they died to defend, flown proudly at full height
This is why you'll sometimes see people correct the flag being left at half-staff all day on Memorial Day — that's actually not the proper observance per the U.S. Flag Code.
