Switzerland Working Day

Checks a date against the Saturday-Sunday weekend baseline and exact 2026-2027 authority events.

When to use

You need a deterministic Switzerland Switzerland federal public holiday layer for 2026-2027 result.

Do not use when: Federal layer only. Cantonal public holidays, municipal holidays, employer, collective-agreement, school, bank and exchange schedules are not inferred; Swiss law permits cantons to recognize additional holidays.

Example user requests

Switzerland: Swiss National Day.
Switzerland: Cantonal holiday is not inferred.

Formula

is_working_day = not an official Saturday/Sunday weekend date and no exact authority event

FAQ

Does this package include Swiss cantonal holidays?

No. The Swiss Confederation identifies 1 August as the only federal public holiday; cantonal holidays vary and require a canton-specific package.
