The Swiss National Day (German: Schweizer Bundesfeier; French: Fête nationale Suisse; Italian: Festa nazionale svizzera; Romansh: Fiasta naziunala Svizra) is 1 August. It is inspired by the mention of “early August” (primo incipiente mense Augusto) in the Federal Charter of 1291. It was first celebrated in Berne in 1891, marking the 600th anniversary of the charter. It displaced the formerly more prominent traditional date of the Rütlischwur, 8 November 1307. Based on that date, in 1907, the 600th anniversary was celebrated in Altdorf. In 1941, the 650th anniversary was celebrated.
