Business Day Calculator Alternatives and Tool Comparisons

Last reviewed: October 14, 2026

There is no single best way to count business days. A spreadsheet formula wins when you already have the data in columns. A phone-friendly web tool wins when you are away from your desk and just need a date. The pages below compare this calculator against a spreadsheet formula and two other online tools, and they are written to help you pick the right one, not to win every row.

The Excel and Calculator Soup comparisons set out what the other option does, read from its own pages and linked, with a feature table and a plain recommendation for when to use which. Where the other tool is the better answer, the page says so.

What it covers, what you have to do by hand, and when automatic country holidays matter.

A quick way to choose

  • Your data already lives in a spreadsheet: stay in Excel or Google Sheets with NETWORKDAYS. See the Excel comparison.
  • You need holidays for many countries at once and time-zone tools alongside them: timeanddate.com has the widest country list. See the timeanddate comparison.
  • You want a fast plain day count and will handle holidays yourself: Calculator Soup is quick. See the Calculator Soup comparison.
  • You want automatic country holidays, custom weekends, a shareable link, or a widget for your own site: start here or grab a free embed widget.

Frequently Asked Questions

Why publish comparisons against other tools?
Because picking the right tool for a one-off date question should not take an afternoon. Each page below sets out what the other tool or function does, from its own pages, and where this calculator fits better. Some jobs suit a spreadsheet, some a phone, and some need public holidays you do not want to maintain by hand.
Is BusinessDayCalculator.org free, and does it need an account?
Yes, it is free, and there is no account, sign-up, or API key. Every calculator runs in the browser, and the embeddable widgets are free to place on any site. Holiday coverage, custom weekends, shareable links, and whether the math runs inside a spreadsheet are what the comparisons look at.
Which countries' public holidays are built in?
25 countries, each with its holiday source cited, plus 88 sub-national regions in United States, United Kingdom, Canada, Australia, Germany, Spain and Switzerland. Each country also has its own working week, so Friday-Saturday weekends are handled, not just Saturday-Sunday.
How current are the competitor details on these pages?
The Calculator Soup page and Microsoft's and Google's function pages were read again on 9 October 2026, and each comparison links the pages it relies on. timeanddate.com could not be read that day, so its comparison states nothing about it for now. Features and pricing change, so confirm anything time-sensitive on the source before relying on it. A fact that could not be checked is left off rather than guessed.
