Berchtold’s Day

Berchtold’s Day is one of the distinctive dates that gives the Swiss festive calendar its regional texture. Its exact origin is uncertain: explanations have connected it to Duke Berchtold of Zähringen, to a medieval church figure, and to older winter gathering customs. What is certain is that January 2 developed into a recognised continuation of the New Year break in many German-speaking cantons.

It is not a Swiss federal holiday and does not apply everywhere. Zurich’s own information separates locally observed dates from its statutory cantonal calendar, while neighbouring cantons can make different choices. That variation is not a defect in the calendar; it is part of how Switzerland gives local communities substantial control over public time.

Swiss public-holiday law is deliberately decentralised. The Federal Constitution establishes August 1 as the one holiday treated like a Sunday throughout Switzerland; cantons may designate up to eight additional holidays with equivalent labour-law effect, and can recognise further dates under cantonal rules. Coverage can therefore differ by canton and sometimes municipality. Employees who work across cantonal borders generally follow the holiday law at their place of work, while contracts and collective agreements govern pay or time-off details not fixed by public law.
