A date can be a holiday in one Canadian calendar and an ordinary working day in another. The answer depends on the jurisdiction and the purpose of the count. It can also depend on whether the question concerns the statutory date or an employee's substitute day.
The calculator keeps those questions separate. Default Mode uses the public-holiday calendar selected under Province or Territory. Court Rules Mode uses a supported court profile. Use a Shutdown Overlay only where the source governing the period includes that closure.
The examples below were checked against the official sources on 3 August 2026. They explain the differences that the annual holiday guide cannot show in one table.
September 30 depends on the selected province
Start on Monday 28 September 2026, exclude the start date and count three working days:
| Province or Territory | Treatment of September 30 | Result |
|---|---|---|
| Ontario | Counted | Thursday 1 October 2026 |
| British Columbia | National Day for Truth and Reconciliation excluded | Friday 2 October 2026 |
Open the British Columbia calculation, then select Ontario to compare the first row. The result changes by one day because British Columbia excludes 30 September and Ontario does not.
That is a calendar result. The contract, statute or court rule still determines which provincial calendar applies.
A statutory date is not always a substitute date
Boxing Day is a general holiday for federally regulated employees and a public holiday in Ontario. In 2026 it falls on Saturday 26 December.
Ontario ordinary mode records 26 December. It does not automatically exclude Monday 28 December, because an Ontario employee whose Saturday is not normally a working day may receive a substitute holiday on another date or, with a written or electronic agreement, public holiday pay instead. The federal planning calendar does exclude Monday 28 December as Boxing Day observed.
The calculator can apply the calendar selected for the period. It cannot reproduce an individual's work pattern, substitute day or private agreement.
Remembrance Day can serve different purposes
The ordinary calculator excludes Remembrance Day in Alberta and counts it in Ontario. In Nova Scotia, the general planning calendar excludes the day, while the Labour Standards Code uses a separate list of paid holidays. A workplace closure, a planning calendar and a holiday-pay entitlement can therefore have different results.
Use the source that governs the period, rather than treating a public holiday list as an answer to an employment-entitlement question.
Court rules can use a different federal list
Easter Monday is not one of the ten general holidays in the Canada Labour Code. It is included in the federal Interpretation Act definition of "holiday", which Federal Courts Rule 6 uses for time computation.
The employment calendar and court calculation have different purposes. A Federal Court period should be calculated in Court Rules Mode, with a seasonal-recess control added only where it applies. It is not a choice between two interchangeable federal calendars.
