(CNN) – Daylight saving time ends this weekend, but what exactly are we falling back to?
Daylight saving time sounds kind of special, you're not just saving time. You're saving daylight time.
But it puzzles the daylights out of some folks why we fall back to standard time.
That's what it's called - standard time.
We spend eight months out of the year in daylight saving time, but standard, which is hardly the standard, is still called standard.
It's been shrinking since World War I. That's when daylight saving time was first implemented to save energy.
The switch made the sunset time, later in the day so people didn't have to turn their lights on as early.
But what about winter, and the fall back to standard?
Well, look at it this way. Most parts of the U.S. only get about 9.5 hours of daylight in winter time.
If we didn't set our clocks back in the fall, sunrise wouldn't be until 8:30 a.m. in many places - you'd be starting and ending your day in the dark.
Falling back to standard keeps the time of dawn, which is a little closer to what we're used to, and it helps us start our day in the light.
Plus, there's that whole extra hour of sleep thing, assuming you go to bed on time when we fall back.
So less daylight, but more sleep, unless you happen to live in Arizona or Hawaii.
Most parts of Arizona and all of Hawaii don't observe daylight saving time.
They don't have to because it's not required by law.
So at least during standard time, they may have an easier time computing time differences for phone calls or travel to other time zones.
After all, that takes time.
