Frequently asked questions
What is a working day?
A working day is any non-weekend day. The default weekend is Saturday and Sunday, but you can choose Friday/Saturday, Sunday only, or Friday only to match other regions.
Are public holidays removed?
No. Only weekends are removed. Public-holiday support is on the roadmap.
How is this different from the Business Days Calculator?
It is the same engine. "Working days" and "business days" are interchangeable terms — use whichever wording you prefer.
Can I exclude the start or end date?
Yes. Use the include-start / include-end checkboxes above the tool.
