This weekend is a holiday weekend since Monday is Swiss National Day. Established in 1994, it celebrates the Federal charter of 1291, what is seen as the pact that formed Switzerland.
I asked my coworkers how Swiss National Day was celebrated. They said "with fireworks and grilling with friends" or "like the Fourth of July". I asked if there were parades and was told "no", but this page describing the Zurich events says there will be a parade. I will let you know next week if and how the parade goes.
Today we avoided the rain and stayed inside. I made a Butterzopf. I made one from a mix, but it was very tasty, so I see no pressing need to try a recipe from scratch. Here is the package with a picture of what it's supposed to look like and what mine looked like.
