Business days calculator
Count weekdays between two dates with the inclusion rule kept visible.
What this calculator covers
Use this business days calculator to count Monday-through-Friday days between two dates.
The walkthrough shows the inclusive calendar span, the weekend days removed, and the final weekday count so the rule stays transparent.
Frequently asked questions
- Are the start and end dates included in the count?
- Yes. The calculator counts both endpoints when they fall on weekdays. If you need to exclude one or both boundary dates, subtract accordingly from the result.
- Does the calculator account for public holidays?
- No. It counts Monday through Friday only and does not remove bank holidays, federal holidays, or regional non-working days. For SLA or contract purposes where specific holidays are excluded, you would need to deduct those days manually.
- What if my start and end dates fall on weekends?
- Weekend boundary dates contribute zero business days to the count. The calculator still works correctly — it simply counts no weekdays from a Saturday start or Sunday end.
- Can I count business days in a future or past year?
- Yes. The date range can span any period the date picker supports, whether historical or future. The weekend-removal logic applies consistently regardless of the year.
