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 counting mode for all eight jurisdictions. Enter the period from the governing rule; the calculator applies public holidays and the statutory Christmas/New Year exclusions.
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.
