Spring Forward: When Do We Change Clocks for Daylight Saving Time?

Make sure you have your clocks right as the clocks jump forward an hour tomorrow Sunday, March 10. Also would be good time to change your batteries in your smoke alarms and carbon monoxide detectors.


It's Daylight Saving Time already again tomorrow. While it might not feel like Spring today, it's coming soon, and that means it is Spring Forward this time.

So when does Daylight Saving start?

Daylight Saving Time starts at 2 a.m. Sunday, March 10. That means you’ll “spring ahead” and move your clocks forward one hour—and, unfortunately, lose that hour of sleep.

The benefit is that we’ll get more sunlight later in the evening and it’s a pleasant sign that spring is just around the corner. (Spring 2013 officially starts on Wednesday, March 20, so prepare for those days to start getting longer)

Many electronic devices, like your cell phone and computer, automatically adjust when Daylight Savings Time begins or ends.

So, why do we do this at 2 a.m., and why shift our clocks at all?

According to Webhibit:

In the United States, 2 a.m. was originally chosen as the changeover time because it was practicaland minimized disruption. Most people were at home and this was the time when the fewest trains were running. It is late enough to minimally affect bars and restaurants, and it prevents the day from switching to yesterday, which would be confusing. It is early enough that the entire continental U.S. switches by daybreak, and the changeover occurs before most early shift workers and early churchgoers are affected.

The larger reason for shifting our clocks, however, is energy conservation.

Ben Franklin first suggested shifting the clocks to save on candles, according to Discovery, but no one took him up on his idea at the time.

The first official national time shift wasn’t until 1918. Then the United States stopped the practice, started again during World War II for energy conservation reasons, stopped when the war was over and re-started with the Uniform Time Act in 1966. The Energy Policy Act of 2005 lengthened daylight saving to eight months instead of six months.

Does Daylight Saving actually save energy?

Discovery News reported:

Although a U.S. Department of Transportation study in the 1970s found that daylight saving trimmed electricity usage by about 1 percent, later studies have shown that the savings is offset by air conditioners running in warmer climates.

It may not all be for naught, however. Another study, performed in 2007 by the RAND Corporation found that the increase in daylight in spring led to a roughly 10 percent drop in vehicular crashes.

When you change your clocks in the fall and spring because of Daylight Saving Time, it’s also a good time to change batteries in your smoke and carbon monoxide detectors, and check to make sure the devices are in working order.
