Swiss National Day is celebrated on August 1st each year to mark the founding of the Swiss Confederation in 1291. This day commemorates the signing of the Federal Charter, which united the three original cantons of Uri, Schwyz, and Nidwalden in a mutual defense pact. The celebration includes various festivities such as fireworks, parades, and speeches. Many people gather in their communities to enjoy traditional Swiss food and music. It is a day for Swiss citizens to express their national pride and reflect on the values of unity and freedom that define Switzerland.
