Girl With The American Flag

To properly fly the flag at half-staff, one should first briefly hoist it top of the staff, then lower it to the half-staff position, halfway between the top and bottom of the staff. Similarly, when the flag is to be lowered from half-staff, it should be first briefly hoisted to the top of the staff.
Only state governors can decide to lower the flag to half staff, according to US Code.
Federal guidelines state the flag should be flown at half-staff at the following dates/times:
May 15 – Peace Officers Memorial Day, unless it is the third Saturday in May, Armed Forces Day, full-staff all day
