Valais Business Day Calculator
Last reviewed: May 19, 2026 · Holiday data: June 24, 2026
Calculate business days in Valais with its own cantonal public holidays. Valais shares the Monday to Friday working week and the Saturday and Sunday weekend with the rest of Switzerland, but its holiday calendar is different, so due dates and deadlines can land differently from the national count.
How Valais differs from the national Swiss holidays
Valais is the most distinctive Swiss canton for working-day math. It does not observe four days that are holidays almost everywhere else: Vendredi saint (Good Friday), Lundi de Pâques (Easter Monday), Lundi de Pentecôte (Whit Monday) and Saint-Étienne (26 December) are all ordinary working days in Valais. In their place it keeps a strongly Catholic calendar, adding Saint-Joseph (19 March), Fête-Dieu (Corpus Christi), Assomption (15 August), Toussaint (1 November) and Immaculée Conception (8 December). The official cantonal list runs to ten holidays in total. Valais is bilingual, French and German; the French names are used here. The net effect is that a Valais deadline around Easter can land earlier than the national one, while the autumn feasts push it later.
Worked example
Adding 1 business days to Thursday, April 2, 2026 using Valais's holidays lands on Friday, April 3, 2026. With the national Swiss holidays, the same calculation lands on Tuesday, April 7, 2026: the gap comes from Valais's own calendar.
