What it is and what it does
chinese-calendar is a Python library that answers a single, practical question: is a given date a working day or a holiday in China? It encodes the official holiday schedules published by China's State Council, covering 2004 through 2026, and includes special handling for adjustments like the 2020 Spring Festival extension. The library provides three main functions: checking if a date is a holiday or workday, retrieving the holiday name when applicable, and identifying whether a holiday falls on a makeup workday (调休).
The package has no external runtime dependencies and installs as a pure Python wheel. It is actively maintained and typically receives updates around November each year to incorporate the next year's official holiday schedule. With 1366 GitHub stars, it serves developers building Chinese business applications, scheduling systems, and calendar tools that need to respect China's official working calendar.
Use it for
- Validate whether a date is a working day in China for payroll, leave-tracking, or HR systems.
- Build a calendar UI that highlights Chinese holidays and makeup workdays for end users.
- Filter or exclude holidays from business logic in financial or trading applications operating in China.
- Generate reports or analytics that account for China's official holiday schedule.
- Implement scheduling or availability systems that respect Chinese working days.
