BOISE, Idaho — Don't forget to turn your clocks back before your go to bed Saturday night.

You will gain an hour of sleep, but we'll lose an hour of daylight starting Sunday night.

Daylight Saving Time officially ends at 2 a.m. on Nov. 3. Most smart phones will automatically adjust.

Hawaii and Arizona both operate on standard time year-round.

Supporters of year-round Daylight Saving Time argue that switching clocks negatively impacts our health, and extra hours of daylight in the evenings would reduce deadly crashes and crime.

As you change the time on your clocks, firefighters say it's also a good time to change the batteries in your smoke detector.

They say those batteries should be replaced at least once a year, so the end of Daylight Saving Time is a good way to remember.

Daylight Saving Time returns on March 8, 2020.
