Working Days Calculator
Count business days (Mon–Fri) between two dates, with weekends broken out separately.
Working Days, Not Calendar Days
Project deadlines, SLA windows, and leave balances are counted in business days — not calendar days. This tool gives you both: total days, weekday count, and weekend count.
Useful For
- Project timelines and Gantt estimates
- Delivery/shipping SLA windows ("5 business days")
- Annual leave planning and days-off counting
- Invoice due-date calculations (NET 30 business)
Note: public holidays vary by country — subtract them manually if strict accuracy is needed.
Frequently Asked Questions
What counts as a working day?
Monday through Friday. This calculator excludes Saturdays and Sundays. Public holidays vary by country and are not excluded automatically.
How do I subtract public holidays?
After getting the raw working-day count, subtract the number of statutory holidays in your country that fall in the range. We show the count separately so you can adjust manually.
Does this include the start and end date?
Yes — if both are weekdays, they're counted. If either is a Saturday or Sunday, it's excluded from the working-day total.
Can I see only weekend days?
Yes — we show total days, weekdays, and weekend days separately, so you can see whichever split you need.
