The onset of daylight saving time for 2024 is just around the corner. This year, daylight saving time commences on Sunday, March 10, at 2 a.m. local time. Although this transition means losing an hour of sleep due to the “spring forward” adjustment, it also heralds the arrival of longer daylight hours in the evenings.
Daylight saving time, spanning from March to November, is a period when the clocks are set forward to extend evening daylight. The shift not only provides extra daylight during the spring and summer but also adjusts for more morning light when we “fall back” in November. However, not all regions in Canada observe daylight saving time, with places like Yukon, much of Saskatchewan, and certain areas in Quebec, Ontario, and B.C. opting to remain on standard time year-round.
The concept of daylight saving time was first introduced to Canada in 1908, following New Zealand entomologist George Hudson’s 1895 proposal to extend daylight hours for his studies. The initiative saw its initial adoption in the towns of Port Arthur and Fort William (now Thunder Bay, Ontario), primarily to afford workers more leisure time in daylight after their jobs.
Internationally, daylight saving time was first implemented by the German Empire and Austria-Hungary in 1916, aiming to conserve fuel during World War I. Despite its intent to optimize daylight usage, the practice has sparked debate due to its potential health impacts, including increased risks of strokes, heart attacks, and car accidents immediately following the time change.
Canadian researchers have also highlighted the adverse effects of daylight saving time, such as “social jet lag,” characterized by disrupted sleep patterns, fatigue, and metabolic disturbances. The adjustment is particularly challenging in spring, though the shift back to standard time in fall is associated with depression and seasonal affective disorder due to reduced daylight exposure.
The debate over daylight saving time continues across Canada, with some provinces exploring the possibility of abandoning the tradition. However, changes remain pending, often contingent on corresponding decisions by American states sharing the same time zones.
