About Working Day Calculator Canada
Precise, transparent working-day calculations across all Canadian provinces, territories, and the Federal jurisdiction.
On this page
Our purpose
Canadian working-day calculations can change with the selected province or territory, the statutory holiday calendar that applies, substitute day rules, shutdown periods such as the Quebec construction holidays or the Federal Court seasonal recess, and the treatment of the start and end dates. This calculator makes those inputs visible so you can inspect the count it produces.
The tool handles the arithmetic after you provide the trigger date, jurisdiction, and counting settings. It does not decide which legal or contractual rule applies, when a period begins, or whether a result is valid for your circumstances.
Results show the selected inputs and excluded dates. You can export them for checking against the current source or document that governs your calculation.
What the calculator does
The calculator handles every aspect of Canadian working day computation:
- Use statutory holiday calendars for all 10 provinces and 3 territories, plus the Federal option for federally regulated workplaces.
- Apply Mondayisation and province-specific substitute-day handling when holidays fall on weekends.
- Account for Quebec construction holidays, the Federal Court seasonal recess and optional firm/corporate year-end closures.
- Apply supported court deadline calculations for the Federal Court, Supreme Court of Canada and provincial courts in Ontario, Quebec, Alberta and British Columbia.
- Keep multi-stage projects, procurement gates or litigation steps synchronised with up to six consecutive deadline periods.
- Export PDF and ICS records for documentation and calendar integration.
Every calculation shows its work: start date, end date, inclusions, exclusions, and a calendar that numbers the counted days and marks excluded days clearly.

Sources and maintenance
The calculator and supporting content use primary official publications wherever possible. Important calculations should still be checked against the current source that governs your situation.
Baseline holiday dates are generated with the Python holidays library and checked against the official publications listed here. Separately maintained calendars and exclusions use the reviewed sources cited for those features.

About the publisher
Working Day Calculator Canada is independently published and maintained by Matt W., a New Zealand legal professional. The work includes maintaining the calculator, documenting its counting controls, checking cited sources, and investigating reported errors. Canadian holiday data and rules are sourced from the official publications cited above.
The site is part of the Working Day Calculator network, which also publishes country-specific tools for New Zealand, the United Kingdom, Australia, and Hong Kong — each built around that country's own rules rather than a shared international default.
