My sunlight
Clocks don’t create light: they move it. See where your light falls, depending on your town and your schedule. Calculated in your browser: nothing is sent.
In Montréal, with your schedule, year-round daylight time would give you +222 hours more light while you are awake, every year.
Compared with today (with clock changes), year-round daylight time adds 74 h of sunshine during your free time, mostly from November to March.

How it is calculated
- “Light while you are awake”: the sun up between your wake-up and your bedtime. For Quebecers as a whole, using the sleep hours reported to Statistics Canada, see the calculation for all of Québec.
- “Free time”: the sun up between your wake-up and leaving home, plus between the end of your day and bedtime.
- Clear horizon, cloudless sky. Mountains, buildings and weather reduce the real light, equally under either system.
- Twilight counts too. After sunset it stays light for about thirty minutes, and before sunrise too. These figures count only the sun above the horizon.
- A daytime schedule, every day. The simulator applies your schedule every day of the year, with no weekends or holidays, and does not handle night schedules.
- Mornings count. That is why the mornings when you leave before sunrise are shown too: that is what daylight time changes in the morning, mostly in December and January.
- Special time zones. The Magdalen Islands and the Lower North Shore live on Atlantic time: for them, the calculation uses Eastern time and is only a comparison.
The same calculation, redone independently in the research folder, gives the same results. All the details are in the method.
