Step-by-step instructions (English)
- Enter the start and end dates of the period.
- Select the weekdays that count as working days and enter any holidays to exclude.
- Calculate and review the working-day, holiday, and non-working-day totals.
計算式と方法
Both dates are included. A date counts as working only if its weekday is selected and it is not in your holiday list. Holidays that fall on unselected weekdays are counted as non-working weekdays, preventing double counting.
使用例
A Monday-to-Friday range contains five working days by default. If Wednesday is entered as a holiday, the result is four working days and one holiday.
When this tool is useful
Count available workdays for a project or compare staffing windows with different schedules. Enter the actual local or organizational holiday dates; the weekday selection also supports schedules that do not follow Monday through Friday.
Common mistakes and limitations
- Both endpoints count when they are selected working weekdays and not holidays.
- No official holiday calendar is loaded automatically. Missing holidays make the working-day total too high.
Practical questions about this tool (English)
What happens to a holiday that falls on a weekend?
If its weekday is already excluded, it remains a non-working weekday rather than being subtracted twice. This keeps the total from undercounting working days.
How is this different from Business Days Calculator?
This tool counts eligible days between two dates. Business Days Calculator starts with one date and moves a specified number of eligible days forward or backward.
