Flag days are usually codified in national statutes passed by legislative bodies or parliaments; however, in some countries a decree or proclamation by the head of state or chief executive can also order a flag day. The statute, or the proclamation or decree, may specify locations where flags are to be flown and how (for example, at full- or half-staff); alternatively, custom may prevail. The Flag Day is naturally a flag flying day.
