Working days calculator
Count the weekdays between two dates, set which days are your weekend, and subtract holidays.
About the working days calculator
Notice periods, delivery windows and project deadlines are often counted in working days, not calendar days. This calculator counts every day between your start and end dates, removes the weekend days you select, and then takes off any holidays you enter. It helps with planning, but check your contract or local rules for how a particular deadline is counted.
How it works
- The calculator goes through each date from the start date to the end date, and counts a date only if its weekday is not one of your selected weekend days.
- Both the start date and the end date are included in the count.
- Working days = counted weekdays minus the number of holidays you enter. You type a number, so it does not know about public holidays in any country.
- Worked example: from Monday the 1st to Friday the 12th, with a Saturday and Sunday weekend, there are 10 weekdays. With 1 holiday, the answer is 9 working days.
- The weekend can be changed, for example to Friday and Saturday, for countries where that is the normal rest period.
How to use it
Step 1
Choose your start date and end date.
Step 2
Tick the days that count as your weekend, and enter the number of holidays in the period.
Step 3
Read the working days, the calendar days and the weekend days removed.
Good to know
- Check whether your contract counts the first day. For a 30 working day notice period, being off by one day can matter.
- Look up the public holidays in your region and add only those that fall on weekdays inside your dates.
- For a deadline, count forward and then add a day or two of slack for delays you cannot control.
Questions
Are the start and end dates included?
Yes, both dates are counted if they fall on a working day.
Does it know my public holidays?
No. Holidays differ by country and region, so you enter how many apply to your date range.
Can I count a half day?
Not directly. Count whole days first, then adjust the result by hand for any half days.
