A day marking an event — which frequently closes nothing at all.
A commemorative day marks an event, a person or a founding. The corpus holds 448 of them, and a large share close nothing: they are observed with ceremonies, flags and media coverage while offices work normally.
The category is worth separating because commemoration and closure are frequently confused when a calendar reports only dates. A day that is genuinely significant nationally and does not stop work is a real operational fact — for anyone scheduling government contact, a media announcement or a public event.
Some commemorations do close everything, and some close only the public sector. The category records what the day is for; the operational status records what it does.
A national day is one kind of commemoration — of the state itself. Most commemorative days mark something narrower.
A day of mourning is a commemoration with a solemn character, and is more likely to restrict activity than to close offices.
