Construction schedule calculator for Québec
Four weeks of work started on July 6, 2026 do not end on August 3: the construction industry shuts down from July 19 through August 1, by obligation. Give a start date and a duration in working days — the tool returns the real date, and names what it removed.
What the tool removes, and why
- Weekends. Saturday and Sunday do not count as worked days.
- The ten paid statutory holidays of the official CCQ calendar. They are not the ones other sectors observe: construction closes on Good Friday AND Easter Monday, and observes Canada Day on July 3, 2026 rather than the 1st.
- The two mandatory shutdowns: July 19 through August 1, 2026 inclusively, and December 20, 2026 through January 2, 2027. Every site covered by the decree is closed — those weeks are not made up.
- Nothing else. Weather, delivery lead times and inspections are not guessed: those are your days, and only you know how many to allow for.
What the tool does not know
The official CCQ dates are published through 2028. Beyond that, the tool removes weekends only, says so clearly, and states that the result is optimistic for that part. A date that merely looks certain would be worse than a warning.
Frequently asked questions
Which days does the tool remove from the calendar?
Weekends, the ten paid statutory holidays of the official CCQ calendar, and the industry's two mandatory shutdowns — July 19 through August 1, 2026 inclusively, and December 20, 2026 through January 2, 2027. These are not the holidays other sectors observe: construction closes on Good Friday AND Easter Monday, and observes Canada Day on July 3, 2026 rather than the 1st.
What happens if my start date falls on a non-working day?
The tool moves nothing silently: it starts the calculation on the next working day and says so on screen, with the date it used. A start set for July 22, 2026, in the middle of the summer shutdown, becomes a start on August 3 — which is exactly what happens on a real job, except that here you know before promising it to the client.
How far ahead is the calculation reliable?
The official CCQ dates are published through 2028: beyond that, only weekends are removed, because the holidays and mandatory shutdowns are not known yet. The tool then shows a warning and states that the result is OPTIMISTIC for that part. An answer that admits its limit beats a date that merely looks certain.
Why not simply count in calendar days?
Because the calendar lies on a Québec job site. Three days lost on July 17, 2026 do not push to July 20 but to August 5: the site is closed in between. One day lost on June 23 pushes to the 25th, not the 24th. And the slip propagates to every following phase — which is how a schedule drifts a little more with each line.
