Typically, the autumnal equinox can occur between September 21 and 24, depending on the year.
But what is an equinox? As the Earth orbits the Sun, it does so at an angle. For most of the year, the Earth’s axis is tilted either toward or away from the Sun. This means that the Sun’s heat and rays fall unevenly on the northern and southern halves of the planet.
At the equinox, the Earth's axis and orbit align so that both hemispheres receive an equal amount of sunlight.
The word equinox comes from two Latin words meaning “equal” and “night.” That’s because during an equinox, day and night last roughly the same amount of time—though you might benefit from a few extra minutes, depending on where you are on the planet. In Montreal, true “equinoxes” occur three days after the September equinox and three days before the March equinox, explains Space for life.
The vernal equinox, or spring, occurs between March 19 and 21. This year, spring in the Northern Hemisphere will arrive on March 19, 2024.
What is a coup?
The solstices mark the times of the year when the Earth is tilted most toward or away from the Sun. This means that the two hemispheres receive very different amounts of sunlight, and that day and night are most uneven.
During the summer solstice in the Northern Hemisphere, the upper half of the Earth is tilted toward the Sun, creating the longest day and shortest night of the year. This solstice occurs between June 20 and 22. In 2024, the longest day of the year was June 20, 2024.
Meanwhile, at the winter solstice, the Northern Hemisphere is tilted away from the sun, resulting in the shortest day and longest night of the year. The winter solstice occurs between December 20 and 23. In 2024, it will be held on December 21 at 5:20 a.m. (EST).
Equinoxes mark the beginning of spring and fall. Solstices mark the beginning of summer and winter.
When do we turn back the clock in Quebec?
In Quebec, the return to Eastern Standard Time (EDT) will occur during the night of November 2 to 3, 2024 at 2 a.m.
This is good news for those who love to sleep, because we will gain an hour of sleep. However, studies show that changing the time twice a year has negative effects on sleep, mood and concentration in many people, especially young children.
This time change also means winter will come with the sun setting earlier in the evening. In fact, we will lose clarity every night.
