Working days versus calendar days
A working-day count strips out the weekends, which is why "10 business days" is two full weeks rather than ten calendar days. This calculator walks the range one day at a time and counts only Mondays through Fridays, including both endpoints. Public holidays are deliberately left in — they vary by country and even by region, so the honest thing is to show the weekday count and let you subtract the holidays that actually apply where you are. For a plain calendar-day gap, use days between dates; to see which ISO week a deadline lands in, use the week number tool.
Frequently asked questions
- How many business days are between two dates?
- Enter a start and end date and this tool counts the working days — Monday to Friday — between them, both dates included. From today, 2026-08-02, there are 109 working days left until the end of 2026.
- Which days count as business days?
- By default, business days are Monday through Friday, and Saturday and Sunday are excluded. Public holidays are not removed automatically, because they differ by country and region — subtract any that fall on a weekday for your own location.
- Are the start and end dates included?
- Yes. The count is inclusive: if both your start and end dates are weekdays, they are both counted. A single weekday selected as both start and end returns one business day.
- Why do notice periods and delivery estimates use business days?
- Contracts, shipping estimates and payment terms are usually written in working days because weekends are not counted as operating days. "Within 5 business days" starting on a Thursday, for example, lands on the following Thursday, not the Monday.
