Calculate working days, court deadlines, and SOPA timelines in Australia across all states and territories, with public holidays, court-rule baselines, and explicit court controls where the governing rule makes them apply.
Calculate end dates or count days between two dates using Australia's state and territory public holidays, including observed substitutions and regional show-day differences where they apply. Switch between working-day and calendar-day modes for conveyancing completions, contract deadlines, and ordinary business timelines.
Sequential mode lets you chain up to six deadline periods for property settlements, construction payment schedules, and other multi-stage timelines where one deadline triggers the next.
Disclaimer: Use at your own risk and verify deadlines against the governing statute, contract, or court rules.
Enable Court Rules Mode for the Federal Court, High Court, and supported state or territory courts. The calculator keeps short-period rules, registry-open-day logic, and optional recess exclusions explicit so you can match the governing rule without hiding important assumptions.
Use SOPA mode for construction payment timelines, then switch regions to pick up state and territory holiday differences, including local show-day and substitution effects where they apply.
Switch between working-day and calendar-day counting, control direction, and include or exclude boundary dates to match contract or statute wording.
Chain up to six deadline periods in Default Mode for property settlements, SOPA payment schedules, and litigation workflows where timelines build on each other.
Apply Federal Court, High Court, or state/territory court rules (NSW, VIC, QLD, WA, SA, TAS, NT, ACT), including short-period thresholds, registry-open-day logic, non-court-day roll-forward, and explicit court-recess controls where the governing rule makes them apply.
Select NSW, VIC, QLD, WA, SA, TAS (North/South), ACT, or NT to apply region-specific public holidays and observed substitutions. In High Court mode, also select the relevant Registry location.
Security of Payment Act mode for NSW, QLD, VIC, SA, WA, and ACT construction payment claims, counting Mon-Fri excluding public holidays and applying state-specific Christmas/New Year shutdown windows.
Federal and state/territory public holidays included, with automatic Monday substitution when holidays fall on weekends (varies by state).
Standard Mon-Fri business day definition (excluding Saturdays, Sundays, and public holidays) used in conveyancing, banking, and commercial contracts.
Visualize the result through a colour-coded timeline showing working days, weekends, public holidays, and court/shutdown periods.
Review excluded days, any selected court-rule controls, and export the calculation parameters and audit trail to PDF.

Australia has only seven nationally consistent public holidays. Everything else varies by state—and some variations are genuinely surprising.

Substitute day rules are one of the most misunderstood parts of Australian public holiday law. Get them wrong and you've miscounted your deadline by a day.

Melbourne Cup Day is statewide by default, yet many regional councils move it to a different local show day.
Australian deadline calculations vary by state, court jurisdiction, Registry location, and industry. Federal and state/territory court rules use different short-period thresholds, registry-closed or court-closed day sets, and in some cases explicit vacation or recess exclusions. 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 the Federal Court, High Court, 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. Where a court rule excludes a recess period only in specific circumstances, the calculator presents that as an explicit rule control instead of assuming it always applies.
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 feedback@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 jurisdictions and court profiles without spreadsheets or manual holiday lookups.
