(CNN) - Mid-South residents are getting ready to gain one hour Sunday.
That's right, Daylight Saving Time is officially at 2 a.m. Sunday.
Yet, many people are puzzled why we fall back to the standard time. Several residents are especially confused because the old standard has been shrinking since World War I.
Daylight Saving Time was first implemented to save energy.
The switch made the sunset time later in the day.
Experts said the reason for the change is because many parts of the U.S. only get about 9.5 hours of sleep.
In essence, if the change was not made, people will be beginning and ending days in the dark.
The fall back to standard time keeps the time of dawn a tad closer to what we are used to.
