Open Calculator

A step-by-step guide to ordinary counts, Canadian holiday calendars, court jurisdictions, optional rules and results.

Last reviewed: August 2026

Step 1

Choose the calculation you want to run

At-a-Glance

•Manual rules handle one ordinary count or date difference
•Court rules apply one maintained court jurisdiction
•Sequential joins two or more documented stages

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

Manual rules

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 jurisdiction.

Sequential

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

Find the inputs in the governing source

Use the statute, rule, order, contract or policy for the trigger date, period, calendar and boundary wording. Confirm those details from the source before entering the settings.

Try it as you read

The three choices appear at the top of the form.

Open the calculator

Manual rules

Run an ordinary business-day or calendar-day count

At-a-Glance

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

Leave Use court rules off, 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.

Deadline or Days between

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

Direction

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

Counting method

Working days exclude weekends, dates in the selected holiday calendar and any additional excluded periods. 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.

Holiday calendar

Choose the applicable Jurisdiction and any item required under Additional excluded periods.

Dates to include

Include the start date only when it forms part of the period, then match the end-date choice to the source wording.

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 calendar at a time
•Federal is a federal calendar, not a union of every province

The Jurisdiction control appears for working-day calculations in Manual rules. Select the calendar named by the source or workflow.

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 calendar. It does not add every provincial and territorial holiday to one count.

Observed dates and individual entitlements

A holiday calendar contains the dates published 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

Compare Family Day, September 30 and Remembrance Day examples.

Conditional controls

Set Quebec Easter treatment and other exclusions

At-a-Glance

•Quebec exposes a Good Friday or Easter Monday choice
•An item selected under Additional excluded periods removes dates from a manual 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.

Public holiday treatment

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

Options under Additional excluded periods

Quebec construction — winter shutdownPublished 14-day CCQ period

Quebec construction — summer shutdownPublished 14-day CCQ period

Law firm year-end closure24 December to 2 January

Company year-end closure27 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 closures

Law firm year-end closure and Company year-end closure 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 Jurisdiction. Court recess controls remain inside Court rules.

Court jurisdictions

Set up Court rules

At-a-Glance

•Choose Backward for a notice or Forward for a filing
•Enter the legally correct trigger date before counting
•Read the live method banner after entering the number of days

Open Court rules when the selected profile matches the court and the type of period being counted. The profile supplies its counting method, holiday calendar, default boundaries and closed-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.

Direction

Choose Backward for a notice counted from an event, or Forward for a filing counted from a trigger. The calculator resolves the compatible sourced court rule and names it under How this will be counted.

Hearing date / Service date

Check the applicable deemed-service or event-trigger rule, then enter the resulting trigger 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 jurisdiction. This is separate from the ordinary Jurisdiction calendar.

The banner is part of the setup

At-a-Glance

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

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

Period 1, Period 2 and later cards

Set the number, Jurisdiction, Additional excluded periods and boundary choices for that stage.

Add another period

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

Move left / Move right

Reorder only when the source requires a different sequence. Every period and its settings remain visible before 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.

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

A holiday is missing

Check Jurisdiction, the calculation year and whether the date belongs to an employment, court or individual substitute-day calendar.

Quebec uses the wrong Easter date

In Manual rules with Quebec selected, check Public holiday treatment. Court rules use the court jurisdiction instead of this ordinary selector.

A construction or year-end period is still counted

Check Additional excluded periods. Selecting a province does not add a shutdown automatically.

The Court calculation 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. If your filing category, local closure or trigger rule is not listed, use the governing source to set up a manual calculation or obtain advice.

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.
