Daylight Savings Time
It is daylight savings time and if you didn't spring forward your clock an hour before bed on Saturday, you may need to do so now to adjust to the 2012 time change. Reuters

Around this time of year, people across the U.S. start to wonder when exactly we will fall back. In 2011, Daylight Savings doesn't end until the morning of Sunday, Nov. 6.

Yet, if Google trends are any indication, people are already beginning to wonder how much longer before they have to change their clocks.

On Nov. 6, you'll move the clocks back one hour and enjoy 60 more minutes of sleep each morning.

If you're feeling like Daylight Savings is coming particularly late this year, that's because of a change that was made a few years back. The Energy Policy Act of 2005 altered the start and end dates of daylight savings time. Beginning in 2007, clocks were set ahead one hour on the second Sunday of March instead of the first Sunday of April. Clocks were then set back one hour on the first Sunday in November rather than the last Sunday of October.

The move was made in an attempt to save energy.

Most, but not all, States and U.S. territories observe daylight saving time. The federal government doesn't require U.S. states and territories to observe it, which is why residents of Arizona, Hawaii, Puerto Rico, the Virgin Islands, American Samoa, Guam, and the Northern Mariana Islands don't change their clocks.

Quick Tip: Daylight Savings is also a good time to change the batteries in all smoke detectors, carbon monoxide detectors, and flashlights.
