It’s that time of year. Be sure to set all your clocks back an hour when you go to bed tonight.
This year is a little different from all the other years though, this year the end of Daylight Saving Time comes on the first Sunday of November (November 4th) instead of the last Sunday of October as it has in the past (for the US; it’s different for other parts of the world).
On August 8, 2005, President George W. Bush signed the Energy Policy Act of 2005. This Act put into effect a change of Daylight Saving Time dates that begins in 2007, so this is the first year we’ve done this (even though the act is about two years old). The Secretary of Energy will do a study of the results of this change and submit the report to Congress, Congress will then decide if it was all worth it and may or may not wind up putting us back on the old schedule. And no… I have no idea what started all this =)
At any rate, Daylight Saving Time now starts on the second Sunday in March (”spring” forward an hour) and ends the first Sunday of November (”fall” back an hour).
It’s interesting to read the history of Daylight Saving Time to see the path its followed over time. From the clever adjustments made by the ancients, to Benjamin Franklin’s suggestion that cannons be fired off at sunrise to awaken the lazy Parisians sleeping the morning hours away.
Franklin’s famous statement: “early to bed, early to rise, makes a man healthy, wealthy, and wise” was an urge to his fellow countrymen to work in the light of day and sleep after dark so as to save money on candles. He calculated that if all the families of Paris, who usually caroused until late at night and slept until noon, would make a habit of rising with the sun, 64 million pounds would be saved in a six month period on candle wax alone! He suggested, half jokingly: “to ring church bells at sunrise, and if that was not enough, let canon be fired in every street to wake the sluggards.”
As an amusing side-note to his interest in the saving of money on candles, Benjamin Franklin’s father, Josiah Franklin, was a tallow chandler, a maker of candles and soap; so he was intimately familiar with this topic.
You can read more on the Daylight Saving Time schedule change at http://tf.nist.gov/general/dst.htm where you can pick up bits of information such as this:
“DST was formally introduced in the United States in 1918. Today, most of the country and its territories observe DST. However, DST is not observed in Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands and the state of Arizona (with the exception of the Navajo Indian Reservation, which does observe DST).”
As a final note, if you’re ever in doubt of what time it is for any of the US timezones, simply go to http://time.gov/ where you can view the official government atomic clock time (they even tell you how many fractions of a second the estimated margin of error for the displayed time is).
