About Working Day Calculator Australia
Our Mission
Australian working day calculations vary across eight states and territories, each with its own public holiday calendar, substitute day rules, and court time-counting practices. Construction and procurement timelines also bring their own industry-specific rules.
Legal, HR, construction, and project teams spend hours counting dates manually, verifying holiday substitutions, and reconciling local rules. Our mission is to remove that friction with a calculator built for Australian realities.
Working Day Calculator Australia delivers defensible, exportable timelines backed by official sources and transparent methodology.
What We Do
The calculator covers core Australian working day computations:
- State and Territory Holiday Calendars: Accurate public holiday dates across all jurisdictions, including regional show days where applicable.
- Substitute Day Rules: Automatic handling of weekend holiday substitutions.
- Court Rules Mode: Court day-counting thresholds and roll-forward logic aligned to common Australian court rules.
- Construction and SOPA Deadlines: Support for industry-specific working day definitions and shutdown periods.
- Sequential Deadlines: Multi-stage projects stay in sync with chained deadline periods.
- Exportable Audit Trails: PDF and ICS exports for defensible documentation.
Every calculation shows its work: start date, end date, inclusions, exclusions, and a timeline with excluded days clearly marked.
