How to use the calculator
Count business days
Turn on business-day counting to exclude weekends and holidays in the selected region, including any scheduled weekend workdays. Add your own closures and check the calendar’s coverage dates.
Browse the calendar
See holidays and adjusted workdays in Calendar. Mainland China and Taiwan also support lunar date conversion; Japan shows era dates and Taiwan shows Minguo years.
Plan time off
Choose a holiday and your leave budget to find a long break and the dates to request off. Check your employer’s leave policy before making plans.
Business-day rules
Calendar guidance, not legal advice.
“Business day” can differ by contract, employer, market, and location. Always check the selected holiday calendar and its published coverage; add your own dates when organizational closures matter.
