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.
