Flag Day
holiday each year where a flag of a country, territory, or a group of people is celebrated
A flag day is a flag-related holiday, a day designated for flying a certain flag (such as a national flag) or a day set aside to celebrate a historical event such as a nation's adoption of its flag.
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.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Flag Day”, the useful work is to connect “holiday each year where a flag of a country, territory, or a group of people is celebrated” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 24, 2026. The linked authority identifier is Q2916333. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
