Basel-Stadt Public Holidays 2027
Last reviewed: May 19, 2026 · Holiday data: June 24, 2026
Basel-Stadt observes 9 public holidays in 2027: 5 fall on a weekday and 4 land on a weekend, leaving 256 working days across the year. The working week is Monday to Friday with a Saturday and Sunday weekend, the same as the rest of Switzerland; what changes is the cantonal holiday calendar.
How Basel-Stadt differs from the national Swiss holidays
Basel-Stadt keeps the national Swiss public holidays and adds one statutory cantonal day: Tag der Arbeit (Labour Day) on 1 May, treated as equal to a Sunday across the canton. The Basler Fasnacht, the three days of carnival that begin with the Morgestraich, closes shops and offices but is not a legal public holiday, so it stays out of the count, the same treatment given to Zürich's Sechseläuten. No Catholic days are observed canton-wide, and Stephanstag is kept. The working week is Monday to Friday with a Saturday and Sunday weekend.
