Business days calculator — frequently asked questions
Is the tool free?
Yes. The tool is completely free and runs in your browser with no account required.
Are the start and end dates counted?
Both are counted by default, the same way Excel NETWORKDAYS works, and you can exclude either one from the advanced options.
How do I exclude public holidays?
Choose your country to load fixed-date national holidays automatically, then add Hijri or company-specific holidays manually, one date per line.
Is a holiday counted twice when it falls on a weekend?
No. A holiday that lands on a weekend day is counted once, as part of the weekend total only.
Can it find a delivery date after a number of working days?
Yes. Switch to “Add business days”, enter the start date and the number of working days, and you get the date with its weekday name.
Does it work on mobile?
Yes. The tool is responsive and works on phones, tablets, and desktop browsers.
