What this tool does
Counts the working days between two dates, excluding the weekend days you nominate, with the option to add public holidays by date.
When to use it
- Estimating a delivery date in working days rather than calendar days.
- Working out actual working days for pay or leave.
- Planning a schedule that accounts for holidays.
- Finding how many working days remain until a deadline.
How to use it
- Pick the "From date" and "To date".
- Set the "Weekend days" your country or employer uses.
- Add "Additional holidays", one date per line, if there are any.
- Click "Calculate working days" and read the four figures.
A practical example
Input
A one-month period, with a Friday–Saturday weekend and one public holiday.
Output
The working-day count, alongside the total calendar days, the number of weekend days and the number of holidays excluded.
Limitations
- Weekend days differ between countries, which is why they are set by hand rather than assumed.
- Public holidays are entered manually; the tool does not know any country's holidays automatically.
- A holiday that already falls on a weekend is not counted twice.
Privacy and processing
The dates and the holidays you enter are counted on your device and never leave it.
Technical notes
- The breakdown shown — calendar days, weekend days, holidays — lets you check the arithmetic rather than trusting a single number.
