Luzern Business Day Calculator

Last reviewed: May 19, 2026 · Holiday data: June 24, 2026

Calculate business days in Luzern with its own cantonal public holidays. Luzern 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 Luzern differs from the national Swiss holidays

Luzern is a historically Catholic canton and observes four days beyond the national Swiss set across the whole canton: Fronleichnam (Corpus Christi), the Thursday 60 days after Easter; Mariä Himmelfahrt (Assumption) on 15 August; Allerheiligen (All Saints' Day) on 1 November; and Mariä Empfängnis (Immaculate Conception) on 8 December. Days that are only local are left out of the count: St. Josef (19 March) is kept only in the communes that declare it, and the parish patron-saint feasts are local. So a Luzern count can run several days below the national one, depending on how the four cantonal days fall.

Worked example

Adding 1 business days to Wednesday, June 3, 2026 using Luzern's holidays lands on Friday, June 5, 2026. With the national Swiss holidays, the same calculation lands on Thursday, June 4, 2026: the gap comes from Luzern's own calendar.
