Frequently Asked Questions
Does this tool account for leap years?
Yes. The tool uses standard UTC date calculation which automatically factors in February 29th during leap years (such as 2024 and 2028).
Are federal public holidays excluded from business days?
Because statutory holidays vary significantly between the US, UK, Canada, Australia, and individual state jurisdictions, our business days metric strictly counts non-weekend days (Monday through Friday).
