International Women's Day on 8 March is a regional statutory public holiday in Germany: it is a day off in Berlin and Mecklenburg-Western Pomerania. Elsewhere it remains an important awareness and action day, not an automatic day off.
In Germany, statutory holiday status is regional: Berlin and Mecklenburg-Western Pomerania are off, while most other states keep a normal workday.
Public holiday in Berlin and Mecklenburg-Western Pomerania. The decisive place is not always the home address: workplace, school location and travel destination can each change the answer.
Mark Berlin and Mecklenburg-Western Pomerania separately. Events, rosters and opening hours depend on the concrete workplace or location. That check should happen before booking travel, moving meetings or assuming that school and work calendars line up.
