Fall Back: Change Your Clocks Tonight for the End of Daylight Saving Time

Daylight Saving Time—you either love it or hate it. Some look forward to an extra hour of sleep, others dread adjusting kids' sleep schedules and changing all the clocks in the house.

Whether or not you're a fan, it's here. Daylight Saving Time—which began in March when we set the clocks forward one hour—ends 2 a.m. Sunday, so it's time to set clocks back before you go to bed Saturday to return to Standard Time.

So, why do we observe DST?

Benjamin Franklin first proposed the idea in 1784, according to TimeandDate.com and it has since evolved as a way to make better use of the daylight in the evenings, save energy and even boost tourism.

If you're not a fan of changing the clocks, take heart: It's easier to adjust to the return to Standard Time, according to this ABC news story.

"Generally, it is always easier to stay up an hour later than to go to sleep an hour earlier, so most people have relatively little problem setting the clocks back in the fall," Dr. Steven Feinsilver, director of the Center for Sleep Medicine at Mount Sinai School of Medicine in New York, told Ned Potter of ABC News.

Feinsilver said our body clock seems "programmed" for a longer than 24 hour day.

Since you are already changing your clocks, it is a good time to change batteries also. The Firemen’s Association of the State of New York (FASNY) reminds residents to use Daylight Saving Time to change the batteries in their smoke alarms and carbon monoxide (CO) detectors. The batteries should be changed at least once a year, a simple way to ensure they are working properly.  Remember to test the detectors to determine if it is time to replace them outright
