Iowans, get ready to change your clocks and lose an hour of sleep.

This spring's daylight saving time — the twice yearly tradition of "springing forward" or "falling back" — is right around the corner. Here's what you need to know about the time change in Iowa.

When is daylight saving time 2022?

Daylight saving time starts on Sunday, March 13. Clocks spring forward at 2 a.m. to 3 a.m. CT that day.

You'll get your extra hour of sleep back when daylight saving time officially concludes at 2 a.m. CT on Sunday, Nov. 6.

Why was daylight saving time created?

The U.S. Department of Transportation says that daylight saving time conserves energy. When the sun sets later, it's presumed that people will stay out longer and spend more time outside. Theoretically, that leads to less electricity for lights and appliances.

Benjamin Franklin proposed the idea in 1784 after noticing people burning candles through the night but sleeping past dawn. However, the first national daylight saving time, set forth in a measure known as Standard Time Act, occurred in 1918 as a way to save fuel.

It took on its modern form in 1966 when President Lyndon Johnson signed the Uniform Time Act into law.

Which states don't observe daylight saving time?

There are two: Arizona and Hawaii.

After Arizona observed daylight saving time in 1978, an exemption statute was enacted one year later. Under the Uniform Time Act, Hawaii opted out of the law, too. Hawaii's location — which has limited differences between summer and winter day light hours — was the main factor.
