Don't forget to fall back when Daylight Saving Time ends Sunday


Daylight Saving Time will return to steal an hour of sleep again on Sunday, March 11, 2018. After that, days will get slightly longer - about two more minutes of daylight each day.

There might be some benefits to the time change each year.

The annual change comes in the middle of the night, but most people usually set their clocks back before heading to bed Saturday night.

Daylight Saving is observed in 70 countries and most states in the US, with clocks being set ahead one hour in the spring and back one hour in autumn. We enter the end of Daylight Saving Time during the fall and winter months, and having darkness fall earlier seems to go well with the time and climate. At least it beats losing an hour in the spring? Under the Uniform Time Act, as amended, states can exempt themselves from observing daylight saving time by state law, according to the U.S. Department of Transportation. CNN previously reported that the government starting moving into and out of "Daylight Saving Time" during World War I to copy the Germans, who apparently were using the time change to save fuel.

How can the transition be eased for minimal effect?

In 2012, a University of Alabama researcher suggested "springing forward" could present health challenges, including an increase in the potential for heart attacks.

"The autumn transition is often popularized as a gain of 1 [hour] of sleep but there is little evidence of extra sleep on that night", Ms. Harris said in the study. The idea was that shifting the clock would mean the best hours of sunlight happened at the most opportune time of the day.
