Daylight saving time is coming, and with it, longer, more light-filled days.

Below, your Buzz round up of questions on the time change.

When is it?

We spring ahead the second Sunday in March. This year the time change starts on

Sunday, March 13 and ends Sunday, November 6. Not all states observe the time

difference: Hawaii, most of Arizona, American Samoa, Guam, Puerto Rico, and the

Virgin Islands opt out.

Why do we have daylight saving time?

The hope is that we save energy -- since there's less of a need to switch on

the lights if natural light will do. Studies have shown the electricity

conserved on the new schedule is actually pretty nominal. But look on the

bright side. Those longer light-filled days are sure nice. Searches on the time

switch have increased 797% in the last week. The sunlight-deprived would like

to know "what is daylight saving time," "daylight saving time dates," and

"origins of daylight saving time."

What is the history of daylight saving time?

Fun fact: The idea was first floated back in 1784 by one Benjamin Franklin.

While minister of France he wrote the essay "An Economical Project for

Diminishing the Cost of Light." The idea failed to see the light of day until

practically 100 years later, when the U.S. railroads instituted a standardized

time for their train schedules. That time change was imposed nationally during

the first World War to conserve energy, but was repealed after the war ended.

It became the national time again during World War II.

After that, it was a free-for-all of states deciding if they wanted it, and

when it would start and end. Congress finally enacted the Uniform Time Act in

1966, which decreed that if a state chose to opt in to daylight saving, it had

to be at the same time as everyone else.

Why does it start at 2 a.m.?

The website LiveScience explains that's it's pretty much the least disruptive

time of day to make a switch. After all, most of us are asleep. Those who work

on Sunday usually start later than 2 a.m.

Don't lose sleep over it

While the shift is only one hour, according to Health Day, sleep disorder

specialists say you should prepare yourself: You actually can lose sleep over

the time change. Experts suggest being well rested before the time change by

getting up and going to bed an hour earlier. Our unscientific suggestion: On

Sunday, sleep in.
