What is Jeûne fédéral (Federal Fast)?

The Jeûne fédéral (Federal Fast), known in German as Eidgenössischer Dank-, Buss- und Bettag, is one of the most widely observed holidays in Switzerland. It falls on the third Sunday of September each year and is celebrated in all Swiss cantons except Geneva, which has its own Jeûne genevois on a different date.

Originally a day of prayer, repentance, and thanksgiving rooted in the Protestant tradition, the Federal Fast has become an ecumenical observance shared by both Protestant and Catholic communities. It is a day of quiet reflection, with many businesses and entertainment venues closed.

In the Canton of Vaud, the Monday after the Federal Fast — known as the Lundi du Jeûne fédéral — is the actual public holiday, since Sunday is already a day of rest. The holiday is associated with traditional foods such as plum tart (tarte aux pruneaux) and the famous Züri-Tirggel honey biscuit from Zurich.

History & Origin

The roots of the Federal Fast go back to medieval times, when Swiss communities declared days of prayer and fasting during crises such as wars, plagues, and famines. For centuries, different cantons held their own fast days on different dates — Protestant cantons typically fasted in September, while Catholic cantons had separate dates.

In 1796, the Swiss Diet first attempted to unify the date across cantons, but it was not until 1832 that the Federal Diet formally established the third Sunday of September as the unified date for all participating cantons.

This unification was a rare moment of inter-cantonal agreement before the creation of the modern Swiss federal state in 1848. Originally a Protestant tradition, Catholic cantons gradually adopted the shared date in a spirit of ecumenical unity.

Geneva deliberately kept its own date — the Jeûne genevois — to preserve its cantonal independence and distinct Reformation heritage.

How It's Celebrated

Züri-Tirggel: A traditional Zurich honey biscuit closely associated with the Federal Fast. This delicate, embossed biscuit dates back to the 15th century and is a cherished local specialty.

Plum Tart (Tarte aux pruneaux / Zwetschgenwähe): Especially popular in French-speaking Switzerland and the Canton of Vaud, the plum tart is the quintessential treat of the Federal Fast, made with fresh September plums and crème fraîche.

Church Services: Services are held across Protestant, Catholic, and interfaith congregations, reflecting the ecumenical character of the day.

Day of Quiet Reflection: Many businesses, restaurants, and entertainment venues are closed. It is a day for contemplation, family, and gratitude.

Bettags-Schiessen: In some German-speaking cantons, traditional shooting competitions are held as part of the celebrations.

Lundi du Jeûne fédéral: In the Canton of Vaud, the Monday after is the official public holiday, as Sunday was already a day off. This makes it a long weekend for Vaud residents.
