August 1st is the only nationwide recognized holiday in Switzerland and represents the pact between the cantons of Uri, Schwyz and Nidwalden made in 1291 to cooperatively support one another against external threats. You can read a summary of the Latin text, available here at the Federal Authorities of the Swiss Confederation. This document, the Federal Charter, is regarded as the founding document of the Swiss Confederacy.
So how do you celebrate the Swiss National Holiday? By eating sausages and blowing up small chunks of your beloved land with fireworks of course! And dancing on tables....lots of table dancing.
Next year's plan is to hit the famed "Fire on the Rocks" firework display over the Rheinfalls in Schaffhausen.
Herzliche Glückwunsch zum Geburtstag, Schwyz!
