Daylight saving time: What you need to know

Nov. 2 is when the time changes back one hour for most of the USA.

As the saying goes, spring forward and fall back one hour for daylight saving time.

Here's what you need to know about changing your clocks this year, and the debate over getting rid of DST.

First, when do I need to change my clocks?

Move your clocks back one hour at 2 a.m. Nov. 2. Then on the second Sunday in March, move your clocks ahead one hour.

(Try not to mix it up, like Toronto mayor Rob Ford did in March.)

Ditch daylight saving time?

Arizona and Hawaii are currently the only two states that don't observe daylight saving time.

In Utah, two lawmakers say they will propose a bill to get rid of daylight saving time, reports The Washington Post.

One reason is safety: Parents are concerned about their kids going to school in the dark in the morning, The Post reports.

Also, it's just plainly a pain to change your clocks twice a year.

Earlier this year, an Alabama lawmaker introduced a bill for year-round daylight saving time. The bill would keep the state on Central Daylight Time and not switch twice a year.

"People are tired of springing forward and falling back," Rep. Greg Wren, the lawmaker who proposed the bill, told The Montgomery Advertiser. "A lot of it is simply the fact that it's an archaic standard."

Why does daylight saving time exist?

In 1966, President Lyndon Johnson signed the Uniform Time Act into law.

The idea behind daylight saving time is to take advantage of daylight hours and save energy. But some studies have shown there's minimal energy savings, reports National Geographic.
