Official Sources
The official sources behind each country calendar, including its annual holiday list and applicable scope.
How holiday dates are checked
We begin with a government, public agency, central bank, or other public authority responsible for the calendar. We record the underlying holiday, observed date, multi-day period, and make-up work day separately when the source provides them. Published dates have official-source support, and each page links back to the underlying calendar.
A national calendar cannot describe every school, employer, bank, religious observance, or regional closure. When the scope differs, page notes explain whether an entry applies to government offices, financial institutions, private employers, or a specific region. When an annual timetable is not available, the page includes only supported statutory dates and clearly distinguishes them from extended breaks and adjusted workdays.
