Working Days Calculator
Free Business Days Calculator to calculate the number of working days between two dates, excluding weekends, quickly and accurately.
What does this Working Days Calculator do?
This calculator counts the number of weekdays (Monday through Friday) between two dates, excluding weekends — useful for estimating project timelines, shipping windows, or payroll periods.
How the calculation works
The calculator steps through every calendar day between the two dates and counts only those that fall on a weekday, skipping Saturdays and Sundays.
Step-by-step example
From Monday, August 3, 2026 to Friday, August 14, 2026 (10 calendar days), excluding the two weekends in between (August 8–9 and... actually just one full weekend falls within this range), the working day count comes to 10 business days across those two work weeks.
Tips & common mistakes
- This calculator excludes weekends only — it does not account for public holidays, which vary by country and region and need to be factored in separately.
- Different industries define "business days" slightly differently (some exclude the start date, some include both endpoints) — check what convention your specific use case (like a shipping estimate) actually follows.
Frequently asked questions
No — it excludes Saturdays and Sundays only. Factor in public holidays separately for your region.
