American flags will be flown at half-staff from sunrise until noon, then raised until sunset, to honor the nation's fallen.

Since it was established, Memorial Day has had a clear purpose: giving Americans a day to honor those who have died in American wars. Unlike other holidays, its significance also comes with special guidelines on how the American flag should be flown.

In honor of Memorial Day, flags across the United States and Texas are required to fly at half-staff — but only until noon.
