Daylight Savings Time (DST) is nearing its end as colder months fall upon much of the U.S. Instead of long, sunny days, most U.S. states will set their clocks back an hour and enjoy an extra hour of sunlight in the morning but an earlier onset of darkness in the evening.

Daylight Savings Time ends on Sunday, Nov. 3, at 2 a.m., when clocks go back to 1 a.m. DST usually ends the final Sunday in October, but this year, it occurs on November's first Sunday.

The extra hour could help some folks catch up on the sleep they lost back in March, when Daylight Savings Time made everyone “spring ahead” and lose an hour of sleep.

DST was first proposed by entomologist George Vernon Hudson in 1895 as a way to extend daylight hours in summer. But it was adopted as an energy-saving measure by President Franklin D. Roosevelt in the United States and called "War Time," during World War II, from Feb. 9, 1942, to Sept. 30, 1945. The law was enforced 40 days after the bombing of Pearl Harbor.

These days some states do not partake in Daylight Savings Time. There are mixed studies as to whether or not the time change actually helps to save energy, said.

Those who use personal computers, smartphones, tablets and other electronic devices (just about everyone) don’t have to worry about turning the time back because the devices automatically do it. On the first Sunday in November, however, those who do need to manually set the hour hand back should do so before going to bed.

In March, when everyone “springs ahead,” there are only 23 hours in the day. But when most of the country “falls behind” next month, there will be 25 hours in the day. What will you do with the extra hour?
