What is the Business Days Calculator?
Plain 'days between two dates' math counts every day, including Saturdays, Sundays and public holidays — not much use for estimating when a shipment, payroll run or contract deadline that only counts business days will actually land. This tool counts the real number of business days between two dates for over 100 countries, automatically skipping weekends and that country's real, live public holidays (via a public holiday database), not a static guess.
It also shows the equivalent working hours (business days × your chosen hours-per-day) and total calendar days for comparison, so you can see at a glance how far apart 'calendar time' and 'business time' really are for your date range.

Questions people ask
Does this account for public holidays automatically?
Yes — select a country and it pulls that country's real public holidays for the relevant years and skips them along with weekends, using the same live holiday database as the site's public holiday calendar tool.
How many countries are supported?
Over 100 countries, the same coverage as this site's Public Holidays tool.
Can I count weekdays only, ignoring holidays?
Yes — a toggle lets you count weekdays-only (skip weekends but not holidays) if that's what you need.
Does it include the start and end date themselves?
Yes, both the start and end dates are included in the count if they fall on a business day.
Is my data stored?
No — dates are calculated locally, and the only network request is a live, anonymous lookup of the selected country's public holidays.
