Frequently Asked Questions
What are business days?
Business days are the weekdays Monday through Friday, when most offices, banks, and government agencies are open. Saturdays, Sundays, and public holidays are not business days. This calculator counts the weekdays between two dates and lets you subtract holidays.
How do I count business days between two dates?
Count every day from the start date to the end date, then remove Saturdays and Sundays. This calculator does it instantly, including both the start and end date, and lets you subtract the number of public holidays that fall in the range.
Does this include the start and end date?
Yes — the calculation is inclusive of both the start and end dates. For example, Monday to Friday of the same week counts as 5 business days.
How do I exclude holidays?
Enter the number of public holidays that fall on weekdays within your date range in the "Holidays" field, and the calculator subtracts them from the business-day total. Holiday dates vary by country and state, so count the ones that apply to you.
Why do businesses use business days?
Shipping estimates, payment processing, legal deadlines, and service-level agreements are usually measured in business days because work does not happen on weekends and holidays. "5 business days" can span a full calendar week or more depending on when it starts.
