Reporting a Public Holiday Error
Public holiday dates change. Governments add commemorative holidays, move existing ones, or cancel them. If you spot an incorrect date, include the country, the holiday name, the date showing, and the correct date. We verify and update confirmed errors within 30 days. Holiday data is sourced from Nager.Date, an open-source public holiday API covering 100+ countries. All holiday data used by WorkingDaysCalc comes from verified government sources.
