Day of Repentance and Prayer is mainly Germany's Saxony exception: it is a statutory public holiday in Saxony, while most other states treat the Wednesday as a normal workday. That creates the practical questions for teams, schools and childcare.
Because the date is still widely known, misunderstandings around work, school and availability are common.
Public holiday in Saxony. The decisive place is not always the home address: workplace, school location and travel destination can each change the answer.
Mark Saxony separately. Cross-state teams should align rosters, school, childcare and availability before the November Wednesday. That check should happen before booking travel, moving meetings or assuming that school and work calendars line up.
