On Saturday 15 August 2026, public-holiday rest applies throughout Saarland and only in Bavaria's qualifying Catholic-majority municipalities. There is no substitute Monday.
Reliable planning starts by matching the precise address to the public-holiday area. Only then can rotas, school, opening hours and outings be classified correctly.
Saturday, 15 August 2026, is the relevant date; Germany does not move this public holiday to Monday when it falls on a weekend.
The same date therefore has different consequences inside Bavaria: the state boundary is not enough, and the qualifying municipality must be identified.
