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.

Working hours conversion
Multiplies business days by your chosen hours-per-day to estimate real working hours in the range.

Worked example
Example
March 1, 2026 to March 31, 2026 in the United States → 31 calendar days, but only 21 real business days once weekends and any US federal holiday in that range (none in March 2026) are excluded — at 8 hours/day that's 168 working hours.

Tips for the best results
- Public holidays fall on different dates each year and vary a lot by country — always select the correct country rather than assuming your own country's calendar applies.
- Some countries observe regional or state-level holidays this national database won't include — treat the count as accurate at the national level, and add local holidays yourself if relevant.
- A holiday that falls on a weekend is often observed on the nearest weekday in some countries — this tool uses the exact dates the holiday database publishes, which already reflect each country's own observed-date rules.
Common mistakes to avoid
- Forgetting to change the country and getting an incorrect holiday count for a different country's calendar.
- Assuming weekends are always Saturday/Sunday everywhere — most countries follow that pattern, and this tool uses it, but a few countries have different weekend days not modeled here.
- Confusing calendar days with business days when quoting a deadline to someone else — always specify which one you mean.

Frequently asked questions
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.
Why might the holiday list look outdated for future years?
Some countries only officially confirm certain holiday dates (like those based on lunar calendars) closer to the year in question — this tool always requests the live current data for the years you selected.
