Business days between dates online

How it works

Count business days, weekends and calendar days between dates.

We normalize civil dates to avoid timezone and daylight-saving errors.

What counts as a business day

The tool treats Monday through Friday as business days and separates Saturdays and Sundays. Long ranges are calculated efficiently in your browser.

Official holidays are not removed because they vary by country, region and year. Confirm them with the relevant official calendar for important deadlines.

Tips for a useful result

Decide whether the start date belongs to the period before calculating.
Review local holidays for deliveries, contracts or official procedures.
Compare business days with calendar days to understand the full duration.

Frequently asked questions

Is the result exact?

Day and date calculations are exact. Values shown as months, hours or minutes may be approximate where appropriate.

Which parts of the result are exact?

Dates and calendar-day totals are exact. Conversions to months, weeks, hours or minutes may be approximate when there is no single calendar conversion.

Are my dates sent to the server?

No. The calculation runs in your browser, and entered values are not included in server requests or analytics events.

Can my timezone change the result?

The tool uses civil dates without a time and normalizes them internally, avoiding one-day shifts caused by timezones or daylight-saving changes.

Does it work on phones and computers?

Yes. The interface is responsive and uses features supported by modern desktop and mobile browsers.
