Frequently asked questions

What is a business day?

A business day is any weekday (Monday to Friday) that is not a public holiday. Business-day math is used for contract deadlines, shipping estimates, payroll, and project planning.

How do business day calculators handle holidays?

Our calculators exclude official public holidays for each supported country from 2024 to 2028, including observed holidays when a public holiday falls on a weekend.

Do different countries have different business days?

Yes. Public holidays differ by country, and a few countries observe Friday–Saturday weekends instead of Saturday–Sunday. Choose your country above for accurate results.

Are these calculators free?
