Business Days Calculator
Count working days between two dates, or add working days to a date, excluding weekends and holidays.
Formula
weekdays only, minus any dates you list as holidays
Tips
- Public holidays vary by country and often by region, so they are yours to supply rather than assumed.
- Counting is exclusive of the end date, matching how notice periods and payment terms are usually written.
- When adding business days, the start date itself is not counted — day one is the next working day.
Frequently asked questions
Should the start date count?
Conventions differ, which is exactly why disputes happen. This tool excludes it. Contracts saying "within 10 business days of receipt" usually mean the same, but check the wording rather than assuming.
