Australia Working Day Calculator
Calculate working days and calendar days in Australia across all states and territories, including public holidays, court rules, and SOPA construction payment deadlines.
Australian Working Day & Business Day Calculator
Calculate end dates or count days between two dates using Australia's federal and state/territory public holidays, with substitution rules when holidays fall on weekends. Switch between working-day and calendar-day modes for conveyancing completions, contract deadlines, and court filings.
Sequential mode lets you chain up to six deadline periods for property settlements, construction payment schedules, and litigation workflows where one deadline triggers the next.
Disclaimer: Use at your own risk and verify deadlines against the governing statute, contract, or court rules.
Built for Legal, Construction & Property Teams
Enable Court Rules Mode for Federal Court or any state/territory court (NSW, VIC, QLD, WA, SA, TAS, NT, ACT), where short periods (5-6 days or fewer) run in working days and calendar days apply to longer deadlines. Court vacation periods suspend running timelines in VIC and WA.
Use SOPA mode for Security of Payment Act deadlines in construction contracts (NSW, QLD, VIC, SA, WA, ACT), counting Mon-Fri excluding public holidays, with state-specific suspension periods built in. Switch between 8 states and 2 territories to get region-specific public holiday calendars.

Why We Built This Australia Working Day Calculator
Australian deadline calculations vary by state, court jurisdiction, and industry. Federal and state/territory court rules apply hybrid day-counting thresholds (5-6 days or fewer in working days), VIC and WA courts have vacation periods that suspend timelines, and Security of Payment Act (SOPA) deadlines count Mon-Fri excluding public holidays, with state-specific Christmas shutdown windows applied. Conveyancing completions use strict business day definitions, while contract notice periods may run in calendar days or working days depending on the governing terms.
Working Day Calculator Australia brings those rules together in one tool. Toggle Court Rules Mode for Federal or state/territory court timelines (NSW, VIC, QLD, WA, SA, TAS, NT, ACT), switch to SOPA mode for construction payment claims, and select your state or territory to apply region-specific public holidays with automatic substitution rules.
The calculator is built for litigation teams, conveyancers, and construction project managers who need consistent, defensible timelines across Australia's eight states and two territories. Browse the use cases page for court filing, SOPA adjudication, and conveyancing settlement scenarios.
If you have a scenario we should support or feedback on state-specific rules, reach us at support@au.workingdaycalculator.com.
The calculator is designed for responsive, mobile-friendly workflows so you can run calculations on-site, in chambers, or from any device where deadlines arise.
Our mission is to give Australian legal, property, and construction teams a precise, defensible timeline for every deadline across all jurisdictions--without spreadsheets or manual holiday lookups.
