Mark your calendars: Time will spring forward an hour for most of you soon, robbing you of an hour of sleep but guaranteeing more sunlight during the day.
Daylight saving time officially begins at 2 a.m. on Sunday March 9 after clocks switched back an hour on Nov. 3, 2013, to help people adjust to weather changes for the winter.
The time change, however, doesn't apply to everyone. Saskatchewan observes Central Standard Time (CST), one uniform time all year round, in all communities except for Lloydminster.
Numerous areas in B.C., Alberta, Ontario, Quebec and Nunavut also don't observe daylight saving time.
People will no doubt enjoy an extra hour of sunlight in the evenings, but the lost hour of sleep has its costs, according to one study.
The lack of sleep can cost the American economy as much as $434 million, Dan Schecter, creator of SleepBetter.org, said last year.
He came up with the estimate by looking at incidents of heart attacks, workplace injury in mining and construction, and cyberloafing as they relate to daylight saving time, though the financial toll may be even higher when accounting for car accidents and injuries in other fields.
There's also a humourous side to the time change. Twitter users last year blamed problems such as a sleepy drive to work and an early start to the day on daylight saving time.
