Business Days Calculator Australia – Working Days Between Dates
Count Australian working days between two dates, or move a date forward or back by a number of business days. Weekends are always excluded. Public holidays come from the official 2026 and 2027 lists already used on thepublic holidays pages — they are not copied into a second table.

The span is inclusive. Every weekday from the earlier date through the later date is a candidate. Saturday and Sunday are dropped. A weekday that appears on the selected state’s official public holiday list is dropped unless it is only a regional or part-day observance and you have left those options off.
Example without a holiday: Monday 5 January 2026 to Friday 9 January 2026 is five working days. Example with a holiday: Monday 26 January 2026 to Friday 30 January 2026 is four working days in every state, because Australia Day is a Monday that year.
Adding business days starts the day after the from date. One business day after Friday 23 January 2026 is Tuesday 27 January 2026, because the weekend and Australia Day Monday are skipped.
Public holidays used here
Dates are read from the existing public-holidays data files for2026 and 2027. National weekdays such as Good Friday sit alongside state-only weekdays such as Labour Day, which is not on the same date everywhere. Local show days, the NSW Bank Holiday, and evening part-day holidays are labelled in that source data and stay optional here.

Frequently Asked Questions
What counts as a business day in this calculator?
A business day is a Monday to Friday that is not an excluded public holiday for the state or territory you select. Saturday and Sunday never count. Statewide gazetted holidays from this site’s official lists are skipped. Regional show days and evening part-day holidays stay in the count unless you turn those options on.
Does the count include the start date and the end date?
Yes. If both dates are working days they are both included. Monday 5 January 2026 to Friday 9 January 2026 is five working days. If the only date in the span is a weekend or a statewide holiday, the count is zero.
How does adding or subtracting business days work?
The from date is not itself counted. Adding one business day to a Friday returns the next Monday, or a later weekday if Monday is a statewide public holiday. Subtracting moves backward the same way. An offset of zero returns the from date even if that date is a weekend.
Why can I only use 2026 and 2027?
This calculator only covers dates in years that have official public holiday data on this site (currently 2026 and 2027). Dates outside that window are rejected because weekend-only maths would miss gazetted holidays. When a later official list is added to the public holidays pages, this calculator can use those years without a second copy of the dates.
Which public holiday list is used?
The calculator reads the same state government dates already published on this site for 2026 and 2027. It does not scrape other websites or invent substitute days. Open the matching public holidays page to see names, notes and source links.
Is this legal or employment advice?
No. This page is general information so you can plan around weekends and gazetted holidays. It is not legal advice, not an award interpretation, and not financial product advice. Whether a day is a public holiday for your workplace depends on the official gazette, your award or agreement, and any local observance. That approach follows ASIC’s general-information standard: we do not advise on a specific product or your personal situation.
