Business Days Calculator
Choose two dates to count how many weekdays (Monday–Friday) fall in that inclusive range, along with weekend days.
How it works
Both ends of the range are included. A Monday through Friday in the same week is 5 business days. A single Monday is 1; a single Saturday is 0. Date order does not matter. Only Saturday and Sunday are treated as weekend — national or regional public holidays still count as weekdays unless you subtract them yourself. This is a weekday counter, not a payroll or legal working-day engine.
Formula
Business days = count of Mon–Fri dates from start through end (inclusive)
Worked examples
- 2024-01-01 (Mon) to 2024-01-05 (Fri) → 5 weekdays, 0 weekend days
- 2024-01-05 to 2024-01-08 → 2 weekdays, 2 weekend days
Useful notes
- Public holidays are not excluded.
- This is different from “days between dates,” which counts every calendar day as a duration and does not include both endpoints the same way.
FAQ
- Are public holidays excluded?
- No. Only Saturday and Sunday are skipped. A Wednesday holiday still counts as a business day here.
- Does the range include both dates?
- Yes. The start and end dates are both counted when they fall on a weekday.
- What if I reverse the dates?
- The same span is counted. The tool always uses the earlier date as the start of the range.
