How to use the Canada calculator

A step-by-step guide to ordinary counts, Canadian calendar layers, court profiles, optional controls and results.

Last reviewed: August 2026

Step 1

Choose the calculation you want to run

At-a-Glance

•Default Mode handles one ordinary count or date difference
•Court Rules applies one maintained court profile
•Sequential Periods joins two or more documented stages

Start with the shape of the calculation. The active choice changes the controls underneath it.

Default Mode

Add or subtract one working-day or calendar-day period, or compare two dates already known.

Court Rules

Count a notice, service or filing period using a selected Canadian court profile.

Sequential Periods

Build a timetable in which the result of one stage becomes the start of the next.

The source supplies the inputs

Use the statute, rule, order, contract or policy for the trigger date, period, calendar and boundary wording. The calculator applies the settings entered; it does not classify the source or select a legal period.

Try it as you read

The three choices appear at the top of the form.

Open the calculator

Default Mode

Run an ordinary business-day or calendar-day count

At-a-Glance

•Deadline uses one date and a period
•Difference compares two dates
•Boundary boxes follow the wording of the source

Select Default Mode, then work down the form in the order shown. A period stated in calendar days stays a calendar-day period even when its final date may move from a weekend or holiday under the source.

Calculation Mode

Use Deadline for a start date plus a period. Use Difference when both dates are already available.

Direction

Forward counts after a start event. Backward works back from a hearing, closing or other target date.

Working Days / Calendar days

Working days exclude weekends and dates in the selected holiday and shutdown layers. Calendar days count consecutive dates.

Number of days

Enter the period stated by the source. Weeks and months use their separate period controls when available.

Include start date

Turn this on only when the first date forms part of the period.

Include deadline date / Include end date

Match the last-date wording. The label changes between Deadline and Difference calculations.

A small boundary check

Start on Monday and add three calendar days. With the start excluded and the deadline included, Thursday is day 3. Including the start instead makes Wednesday day 3.

Check the source wording

See how working days, calendar days and boundaries differ.

Holiday calendar

Choose Federal, province or territory

At-a-Glance

•The selector loads one holiday layer at a time
•Federal is a federal calendar, not a union of every province

The Province or Territory control appears for working-day calculations in Default Mode. Select the calendar named by the source or workflow.

Alberta
British Columbia

New Brunswick
Newfoundland and Labrador
Nova Scotia
Northwest Territories
Nunavut
Ontario

Quebec
Saskatchewan

Ontario and Quebec at Family Day

A one-working-day count from Friday 13 February 2026 finishes Tuesday in Ontario and Monday in Quebec because the Ontario calendar excludes Family Day.

Federal means one calendar

The Federal option loads the calculator's federal holiday layer. It does not add every provincial and territorial holiday to one count.

Observed dates and individual entitlements

A calendar layer contains the dates modeled for that jurisdiction. An employee's substitute day, a workplace closure or a court holiday may come from a different source and may need a different setting.

See which dates differ

Conditional controls

Set Quebec Easter and shutdown overlays

At-a-Glance

•Quebec exposes a Good Friday or Easter Monday choice
•A shutdown overlay adds dates to an ordinary working-day count
•Quebec construction dates are verified through 2028

These controls appear only in an ordinary working-day calculation. They are separate from the holiday calendar and separate from the rule controls inside Court Rules Mode.

Quebec Easter Holiday

This control appears when Quebec is selected. Choose Good Friday or Easter Monday to match the applicable ordinary calendar.

Law Firm Year-End24 December to 2 January

Corporate Year-End27 to 30 December

Quebec construction

The summer and winter options exclude the published 14-day CCQ periods. Dates after the verified range carry an estimate warning.

Private year-end overlays

Law Firm Year-End and Corporate Year-End are optional private calendars. Select one only when the source or actual timetable uses that closure.

One day across Easter 2026

Start on Thursday 2 April and count one Quebec working day. With Good Friday selected, the result is Monday 6 April. With Easter Monday selected, Good Friday remains countable and the result is Friday 3 April.

The controls stay independent

Selecting Quebec does not add a construction vacation. Selecting a shutdown does not change the Province or Territory. Court recess controls remain inside Court Rules Mode.

Court profiles

Set up Court Rules Mode

At-a-Glance

•Select Notice / Service or Filing where the profile supports both
•Enter the legally correct trigger date before counting
•Read the live method banner after entering the number of days

Turn on Court Rules when the selected profile matches the court and the type of period being counted. The profile supplies its counting method, holiday layer, default boundaries and terminal-day adjustment.

Open full size

The Federal Courts profile shows its method, status, supported scope and optional Rule 6 recess control. Select the image to open the full-size view.

Court Rules Workflow

Select Notice / Service to count backward or Filing to count forward. Some profiles support Filing only and lock this choice.

Hearing date / Service date

Enter the source's correct trigger date. The calculator does not apply a deemed-service or event-trigger rule before this date.

Days

Enter the stated period. Threshold profiles can switch method when this number crosses their short-period boundary.

Court Jurisdiction

Select the named court profile. This is separate from the ordinary Province or Territory calendar.

The banner is part of the setup

The banner above the controls shows the active profile label, the method used for the entered period and the fixed boundary reminders. Re-read it after changing the number of days or jurisdiction.

Current profile coverage

Build Sequential Periods

At-a-Glance

•Each period has its own days, calendar, shutdown and boundaries
•The prior result supplies the next period's start
•Review all periods before running the combined count

Turn on Sequential Periods when a documented timetable contains two or more consecutive stages. Each stage remains separately configurable.

Period 1, Period 2 and later tabs

Set the number of days, direction, Province or Territory, Shutdown Overlay and boundary choices for that stage.

Add period

Add the next stage only when the source contains another consecutive period.

Review all periods

Check the hand-off dates and each stage's settings in one view before selecting Calculate.

Check the hand-off boundary

The result of one stage becomes the next start date. Review whether that shared date belongs to the first stage, the second stage, both or neither under the source wording.

If the date looks wrong

Troubleshooting and limits

At-a-Glance

•A one-day difference usually starts with the boundary boxes
•A missing holiday usually starts with the selected calendar or mode

The result is one day early or late

Check Include start date and Include deadline date or Include end date. Then check whether the source uses clear days or a moved terminal date.

A holiday is missing

Check Province or Territory, the calculation year and whether the date belongs to an employment, court or individualized substitute-day calendar.

Quebec uses the wrong Easter date

In Default Mode with Quebec selected, check Quebec Easter Holiday. Court Rules Mode uses the court profile instead of this ordinary selector.

A construction or year-end period is still counted

Check Shutdown Overlay. Selecting a province does not add a shutdown automatically.

The Court Rules method changed

Re-check the number of days against the threshold text in the court banner. Several profiles change from working days to calendar days at a defined boundary.

A recess is still counted

Check the optional rule controls under the court banner. Their availability depends on the court and workflow; they remain off until selected.

The profile is Partial or Limited scope

Read its scope summary and keep the calculation within that stated model. The calculator does not extend a profile to an unlisted filing category, local closure or trigger rule.

The Quebec shutdown result has a warning

The calculator has CCQ-published dates through 2028. A later year uses an estimated pattern until the official dates are added.
