Business Day Calculator – Working Days Between Dates

Our free business day calculator counts the number of working days between two dates, excluding weekends (Saturday and Sunday). You can optionally exclude Australian public holidays so the count reflects actual business days in your state or nationally. This is useful for project timelines, payment terms, contract deadlines, shipping estimates, and any planning that relies on working days rather than calendar days.

What counts as a business day? Typically Monday to Friday, excluding public holidays. Weekends are excluded by default. When you enable "Exclude holidays", the calculator removes common Australian public holidays (e.g. New Year's Day, Australia Day, Good Friday, Easter Monday, ANZAC Day, King's Birthday, Christmas, Boxing Day, and selected state holidays). Holiday lists vary by state—for critical deadlines, confirm with your contract or authority.

Common uses: Project managers use it to set milestones and delivery dates. Legal and compliance teams use it for notice periods and filing deadlines. Finance teams use it for payment terms (e.g. net 30 business days). Shipping and logistics use it to estimate delivery in business days. Use the result as a guide; for legally binding deadlines, always verify with the relevant rules or a professional.

How to use this calculator

Select your start and end dates. Choose whether to exclude Australian public holidays. The calculator shows total calendar days, business days (working days), number of weekends, and optionally holidays excluded.

Frequently Asked Questions About Business Days

What is a business day?

A business day is usually a weekday (Monday–Friday) when businesses and government offices are open. Weekends (Saturday and Sunday) and public holidays are typically not counted as business days.

Are Australian public holidays included?

You can choose to exclude Australian public holidays. When enabled, the calculator excludes common national and some state holidays. Public holidays differ by state and territory, so for exact legal or contract deadlines, confirm the list that applies to you.

Can I use this for contract or legal deadlines?

This tool gives a working-day count between two dates. Many contracts and laws define deadlines in "business days" or "working days". Use the result as a guide, but always check the contract or legislation for the exact definition and any holiday calendar that applies.
