Business Days Calculator

How this tool works

Both start and end dates are included. Choose your regular weekend pattern and supply any additional dates that should not count as working days. A holiday that already falls on a weekend is excluded only once. The calculator uses calendar dates, so daylight saving does not change a day count. National holidays are not added automatically. Check local rules and your employer’s schedule before relying on the result for a contractual deadline. Ranges are limited to one hundred years.

How do I get a useful result?

Start by reading the field labels and the method above. Replace the example values with information that matches your own situation, then use the main button to generate the result. Review the units, dates and any assumptions before copying or printing it. If you change an input, run the tool again so the output reflects your latest choices. An example is a starting point for learning the controls, not a recommendation for your circumstances.

Does this page upload my information?

This tool performs its work in your browser. Its input values are not submitted to a server by the calculator. Closing or reloading the page clears unsaved work. Checklist pages offer an explicit browser-save option; that storage belongs to this browser and device and may be cleared by private browsing or browser settings. Downloads, printed pages and copied text contain whatever information you included, so keep them somewhere appropriate.

Can I use it on a phone?

The form and result panels adapt to a smaller screen. Use your device’s normal keyboard to enter values, and review the output before sharing it. The print button opens the browser’s print controls, where available. Printing and saving as PDF depend on your operating system. If a feature is unavailable, try a current browser with JavaScript enabled. Keep a separate copy of anything important; the page is not a cloud backup service.
