What is Business Days Calculator?
Business days are the days when most offices work, from Monday to Friday. Deadlines, delivery times and legal periods are often given in business days.
What this tool does
The first part counts the weekdays between two dates. The second part adds or subtracts business days from a date and shows the result. Public holidays are not excluded, because they differ by country.
How to use it
- Pick two dates, or leave them empty to use today and 30 days from today.
- Read the business days and the calendar days.
- Use the second part to find a due date.
Did you know?
- Many countries count business days differently, so check how your contract defines them.
- The start date is counted and the end date is not, as in the Date Difference Calculator.
