Frequently Asked Questions

Are public holidays excluded?

No, only weekends are excluded automatically, because holidays vary by country. Subtract them manually if needed.

Is the start day counted?

The count includes the start date if it is a weekday and excludes the end date. For an inclusive count, add 1 when both ends are weekdays.

Can I use it for delivery estimates?

Yes, business days are what most shipping and turnaround estimates use.
