Ascension Day or some other day in May

Time has passed and the event has lost much of its religious character. It is now a traditional festival of the local communities.

Founding of the Swiss Confederation in 1291
Since 1891, the first of August has been celebrated as Swiss National Day. The date refers to a historic alliance concluded in 1291 by the three cantons of Uri, Schwyz and Unterwalden. This alliance was to become the focal point around which the Switzerland of today was built over the next 500 years.
