Practical vexillology

[gfish]

I like flags. The household has quite a few, and we occasionally switches out which one is currently flying, more or less at random. What I want to build is an entire liturgical calendar of flag-relevant events, so they can be switched out every 2-3 weeks (on average).

For example, we have the EU flag to fly during Eurovision. Various pride flags in June, of course. And the UN flag for UN Day (Oct 24). I keep forgetting to buy an Esperanto flag for Zamenhof Day in December. And the French flag for Bastile Day. And NASA (or Apollo program) for July 20.

So I'm turning to you, the internet. What days that have a related flag should we be celebrating? Nothing is too minor, I promise you.

The Star Wars Resistance flag around May 25, the original premiere date of the first film.
Looks like the Articles of the Federation will be signed August 12, 2161, so there's my excuse for the United Federation of Planets.
Founding of Seattle dates to September 25, 1851 so we could fly the city flag.

You could start with a Star Wars flag on May 4th...
