FORT WAYNE, Ind. (WFFT) — Daylight Saving Time begins this weekend.
Before you go to bed Saturday night, make sure to move your clocks ahead one hour.
Otherwise, when you wake up Sunday morning, your home's clocks will not match what's on your cell phone.
It's also a good time to check and change the batteries in your home's smoke and carbon monoxide detectors.
We actually change our clocks in the summer to help reduce electricity use in buildings, according to the U.S. Department of Energy.
It also gives farmers an extra hour of sunlight in the evenings during the summer.
On Saturday, March 7, we'll see the sunrise at 7:04 a.m. and set at 6:39 p.m.
When Daylight Saving Time begins on March 8, we'll see the sunrise at 8:02 a.m. and set at 7:40 p.m.
Daylight Saving Time was adopted by the United States during World War I and World War II, but federal law did not regulate it.
The Uniform Time Act was passed in 1966 and was created to create uniform dates for observing daylight saving time.
For almost 40 years, the Energy Policy Act extended the length of daylight saving time for energy consumption.
About 70 countries in North America and Europe observe Daylight Saving Time.
In the United States, Arizona and Hawaii are the two states that do not observe any time change.
Neither do Guam, Puerto Rico, the U.S. Virgin Islands, American Samoa and the Northern Mariana Islands.
A 2014 U.S. study looked into the heart-related issues one might have from Daylight Saving Time.
It showed that when a person "loses" an hour of sleep, your risk of having a heart-related issue goes up 24 percent.
There's also good news from this study.
When Daylight Saving Time ends and you "gain" an hour of sleep, your heart-related issues actually decrease by 21 percent.
Before April of 2006, Indiana did not observe the time change.
During that time, Indiana counties near Chicago, Illinois, Cincinnati, Ohio and Evansville would change their clocks.
