This weekend, when we set our clocks forward an hour, we’ll be losing a little sleep but marking the centennial anniversary of Daylight Saving Time.

According to USA Today, Daylight Saving Time, which starts its annual eight-month run at 2 a.m. Sunday, was first enacted by the federal government March 19, 1918, during World War I, as a way to conserve coal.

Why it’s stuck around all these years isn’t the question, as far as I’m concerned. For me, the real question is why it isn’t year-round.

Apparently, states across the U.S., including Illinois, have talked about going to Daylight Saving Time all the time. (Note For Sticklers: It’s “Saving” Time, not “Savings” Time.)

Right now, two states — Arizona and Hawaii —don’t move their clocks.

And folks in other states — Florida, for example — are pushing pretty hard to stop the twice-a-year time change.

In February, the Florida House overwhelmingly approved the “Sunshine Protection Act of 2018,” which aims at observing Daylight Saving Time year-round in the state. If approved by the Florida state legislature, the U.S. Congress would have to give its blessing.

For the record, the U.S. Department of Transportation is in charge of time in the U.S., including time zones and daylight saving time.

As you know from reading Kane County Connects about this time last year, the state of Illinois legislature tried to make Daylight Saving Time the year-round standard time for the entire state. Sadly (again, my opinion), the legislation died in 2017.

Daylight Saving Time returns to Kane County, IL, this weekend. Officially we turn our clocks forward an hour, following the old adage, “Spring Forward, Fall Back.”

If you’re a stickler for such things, when local standard time is about to reach 2 a.m. Sunday, March 11, you quickly move all your clocks forward one hour to 3 a.m.

That’s right. We lose an hour of sleep.

Difficult, for sure, but a small price to pay, I say, for the light we gain at the end of the day. And of course, it just gets better from here, as the days get longer and spring draws near.

• Editor’s Note For Sticklers: My old AP Stylebook says “daylight-saving time” is lowercase and hyphenated. For consistency (and so that I don’t have to go back and change last year’s story), we’re using the style folks most often see online.
