Quick Start

Basic calculation

from chinese_workdays import ChineseWorkdays

calc = ChineseWorkdays()
workdays = calc.count_workdays("2026-01-01", "2026-12-31")
print(f"2026年全年工作日: {workdays}天")

Monthly statistics

march_workdays = calc.get_workdays_in_month(2026, 3)  # 22天

Usage Examples

How many working days are there in March 2026?
Working days in Q1 2026?
Calculate workdays between 2026-02-10 and 2026-03-20
How many workdays in 2026?

Command Line

# Quick calculations
python workdays_cmd.py 2026-03          # March 2026
python workdays_cmd.py 2026-Q1          # Q1 2026
python workdays_cmd.py 2026             # Full year
python workdays_cmd.py 2026-01-01 2026-06-30  # Custom range

Data Format

Holiday schedules are stored in YAML format in the data/ directory:

year: 2026
country: "China"
holidays:
  - name: "元旦"
    start: "2026-01-01"
    end: "2026-01-03"
    days_off: ["2026-01-01", "2026-01-02"]  #放假日期
    makeup_workdays: ["2025-12-28", "2026-01-04"]  # 调休上班
    note: "官方通知原文"

Updating Schedules

The State Council releases next year's holiday arrangement in November. Update the YAML file accordingly:

  1. Locate the official notice at https://www.gov.cn/gongbao/
  2. Extract dates and makeup workdays
  3. Edit data/2027.yaml (or the relevant year)

Implementation Details

  • Uses Python's datetime for date arithmetic
  • Holiday data stored as YAML for easy editing
  • Supports makeup workdays that override weekend status
  • Handles holidays that span multiple days

Limitations

  • Requires holiday schedules to be defined for the years being calculated
  • Only works for dates after 2000 (easily extendable)
  • Does not automatically fetch new schedules (manual update needed)
  • Data accuracy depends on correct YAML configuration

Technical Notes

Calculation Priority

  1. Makeup workdays (highest priority) → always counted as working days
  2. Public holidays → excluded from working days
  3. Weekends (Saturday/Sunday) → excluded unless makeup workday
  4. Regular weekdays → counted as working days

Algorithm

for each day in date_range:
    if day in makeup_workdays:
        count += 1
    elif day in public_holidays:
        skip
    elif day is weekend:
        skip
    else:
        count += 1
