Business Days Between
Count Monday-through-Friday days between two dates (inclusive of both endpoints when they are weekdays).
Calculator
Enter two dates to count the business days between them.
How it works
The calculator counts every calendar day from the start date through the end date inclusive, then keeps only those falling on Monday through Friday. Weekends (Saturday and Sunday) are skipped. The result is the number of working weekdays — useful for service-level agreements, project deadlines, and any business workflow that pauses on weekends. Order does not matter: swapping the two dates returns the same count.
Why use this calculator?
Counting business days by hand is genuinely tedious — you have to track week boundaries, remember which days are weekends, and subtract them out of a calendar count. This calculator does it in one operation. Lawyers use it for filing windows that exclude weekends, project managers use it to size sprint deliverables in working days, and contracts often quote delivery times in business days specifically.
FAQ
Are public holidays excluded?
No. This calculator counts Monday through Friday only and does NOT subtract public holidays. Holiday calendars vary widely by country and even by region within a country, so a generic count would be misleading. If you need a holiday-aware count, subtract the relevant public holidays from the result for your jurisdiction.
Are the start and end dates included?
Yes — both endpoints are inclusive when they fall on a weekday. A Monday-to-Friday range counts as 5 business days. A Friday-to-Monday range counts as 2 (the Friday and the Monday). A Saturday-to-Sunday range counts as 0.
Does the order of dates matter?
No. The calculator swaps the dates internally if needed, so entering the later date first or second yields the same business-day count. This is intentional for ergonomics — you should not have to remember which field is 'earlier'.
