Basel-Stadt Business Day Calculator
Last reviewed: October 14, 2026 · Holiday data: October 8, 2026
Calculate business days in Basel-Stadt with its own cantonal public holidays. Like the Switzerland calculator, this page counts Monday to Friday as working days; what changes is the holiday list, so due dates and deadlines can land differently from the Switzerland calculator's count.
How Basel-Stadt differs from the Switzerland calculator
This page counts the eight days of this site's Swiss baseline and adds one Basel-Stadt day: Tag der Arbeit (Labour Day) on 1 May. No baseline day is dropped. 1 May falls on a Friday in 2026, a Saturday in 2027 and a Monday in 2028, so it closes a weekday in 2026 and 2028 only.
Worked example
Adding 1 business day to Thursday, April 30, 2026 using Basel-Stadt's holidays lands on Monday, May 4, 2026. With the Switzerland calculator's holidays, the same calculation lands on Friday, May 1, 2026: the gap comes from Basel-Stadt's own calendar.
