Calculate Canadian business days and working days using the province, territory, federal, or court rule set that matches your matter.
Canada does not have one universal business-day or working-day definition. Provinces, territories, federal matters, court systems, and contracts can use different holiday calendars and counting rules. This calculator keeps those choices visible so you can select the rule set that actually applies.
Use default mode for ordinary working-day calculations with optional shutdown overlays. Switch to Court Rules Mode when you need the court-specific counting rules that apply in the selected jurisdiction.
Disclaimer: Use at your own risk and verify deadlines against the governing statute, contract, or court rules.
Use it to count forward or backward, compare calendar days against working days, or measure the number of days between two dates. Sequential mode helps when one milestone feeds the next, such as finance, due diligence, and settlement.
The calculator gives you the rule tools; you supply the legally correct trigger date. Review the result analysis before relying on the output.
Count forward to a deadline, count backward from an event, or measure the days between two dates. Switch between working days, public-holiday counting, and calendar days as needed.
Chain up to six periods so each result becomes the next start date. Useful for staged Canadian transactions, project milestones, and settlement planning.
Choose whether the start date or end date counts so the result matches the wording in your contract, statute, or court rule.
Federal holidays plus province- and territory-specific holidays are built in, including regional differences such as Family Day variants, St-Jean-Baptiste Day, and Nunavut Day.
Select the jurisdiction that governs the matter so the calculator loads the right holiday calendar and counting rules.
Where the governing rule set recognises observed or shifted holidays, the calculation reflects those dates instead of assuming one national pattern.
Add optional shutdown periods for non-court calculations when your contract, project, or industry practice excludes those dates.
Review the result on a colour-coded timeline showing counted days, weekends, holidays, and excluded dates.
See why dates were excluded, which rule controls were applied, and export the result with its calculation settings.
