Switzerland Business Day Calculator
Last reviewed: May 19, 2026 · Holiday data: May 19, 2026
Calculate working days in Switzerland with the federal-plus-widely-observed Catholic-tradition public holidays preselected. The Swiss federal law mandates only three nationally-binding holidays (Neujahrstag, Bundesfeiertag on 1 August, Weihnachten); each of the 26 cantons adds its own. This calculator uses the set that SIX Swiss Exchange and Swiss banks treat as closure days. Use for ESTV (Federal Tax Administration) MWST quarterly cycles, SIX SIS settlement, SNB Monetary Policy Assessment cycles, and cantonal tax filing windows.

Pair these tools with Swiss B2B workflows
Article 104 of the Swiss Code of Obligations (Obligationenrecht) sets statutory late-payment interest at 5% per annum, payable from the day after the gazetted due date. The Late Payment Interest Calculator computes the running balance for any Swiss invoice; the Invoice Due Date Calculator stages the underlying payment term against the federal holiday calendar.
