How to use
- Pick a start date and an end date to count the working days (Monday to Friday) in between.
- Optionally list any public holidays, one per line, and they will be skipped too.
- Use the second box to add or subtract a number of working days from a date — weekends and the same holidays are jumped over.
FAQ
Are the start and end dates both counted?
Yes. The working-day count includes both the start date and the end date (when they are weekdays), which matches how most payroll and project tools count business days. So Monday to the following Monday is 6 working days.
How should I enter holidays?
Type one date per line in YYYY-MM-DD form, for example 2026-12-25. Only holidays that land on a weekday inside your date range are subtracted; anything that falls on a weekend or outside the range is ignored automatically.
Which days count as the weekend?
Saturday and Sunday. The tool uses the standard Monday-to-Friday working week. If your week is different, you can add the extra days to the holidays list to exclude specific dates.
