OTTUMWA — You’ll get an extra hour of sleep on Sunday, thanks to the end of Daylight Saving Time.
The time change has a long history. Germany was the first nation to use the shift, making the change during World War I in an attempt to save coal. It became an (almost) nationwide step in the United States in 1966. Most states use Daylight Saving Time between the second Sunday in March and the first Sunday of November, but Hawaii and Arizona opt out.
The semi-annual shift has been embraced by emergency services as an opportunity to remind people to change the batteries in their smoke detectors. While some newer models have multi-year batteries, those still using the older styles should swap out the batteries to make sure they’re protected for the next several months.
And, while many devices now get the time from internet connections, items like watches and most alarm clocks will still need to be set back one hour.
Daylight Saving Time will return on March 8, 2020.
