Some areas of the country don't observe daylight time, including some parts of Saskatchewan, Ontario, Quebec, British Columbia and Nunavut.

The need to physically change the time has decreased over the years, as more people rely on electronic devices that automatically switch.

But some are tasked with making sure historic clocks from coast to coast tell the right time.

Craig Potter makes the climb up Citadel Hill in Halifax twice a year to change the city's historic timepiece that's been ticking since 1803.

The back-and-forth debate over following daylight time is also never-ending.

Alberta held a referendum in 2021, and a little more than half of voters wanted to continue changing their clocks.
