How the Custom Holiday Business Day Calculator works
The Custom Holiday Business Day Calculator bring your own holidays — exclude any list of dates from counts. Enter your details, choose the country whose public holidays apply, and the result appears instantly — with no signup, computed entirely in your browser.
Most business processes run on working days — Monday to Friday, minus public holidays. Counting them by hand drifts as soon as a date range crosses a weekend or a holiday, which is precisely what this tool removes.
Worked example
For example, if your date range starts on a Tuesday and spans both a weekend and a public holiday, the Custom Holiday Business Day Calculator skips those non-working days — so the date it returns falls later than a plain calendar count would suggest. The breakdown shows exactly which days were removed.
Frequently asked questions
Does this count weekends and public holidays?
Saturdays and Sundays are excluded automatically, and selecting a country also excludes that country’s public holidays. You can add custom closures for company-specific days off.
Can I use my own holiday list with the Custom Holiday Business Day Calculator?
Yes. On top of the built-in country holiday sets, you can add custom closures — company shutdowns, regional days, or any dates you need excluded from the calculation.
Is it free, and is my data private?
Yes on both counts. Every calculator here is free with no signup, available in 18 languages, and runs entirely in your browser, so the dates you enter are never sent to a server.
