When Does Colorado Switch Off Daylight Saving Time In 2019?

2 a.m., Sunday, Nov. 3, 2019

Another summer come, and another summer gone. Daylight Saving Time ends this weekend for another year, meaning post-7 a.m. sunrises are put off again until December.

So prepare to set back your clocks.

Most digital devices these days handle the change for you, making it easier to forget, but analog wall clocks and plenty of still-good kitchen appliance clocks will need a helping hand. Don't forget the clock in your car — if it's more than a few years old it likely needs a human touch, as well.

Controversial from its introduction during World War I, DST has been a target of lawmakers in Colorado in recent years. The latest legislative effort to revoke the state's membership in the DST club failed in the state House earlier this year.

To the north, Saskatchewan has abandoned the switch. British Columbia is on track to follow and now eyes are on the rest of Canada — which otherwise has long stayed in step with the U.S.

More to know: Whether DST actually saves the energy it's intended to save remains unclear, but as time goes on more research indicates it can have a negative impact on our mental health. Motorists are advised to be especially careful and get plenty of rest as the transition can be jarring.

Until it changes, though, remember that not-so-old adage, "Spring forward, fall back."
