End of Daylight Savings Time 2011

Daylight Savongs Time EndsDaylight Savings Time 2011 ends in the United States on Sunday, November 6. Before going to bed on Saturday, November 5, people will be advised to turn their clocks back one hour (“spring forward, fall back”) and consequently gain an hour of sleep.

Daylight Savings actually ends on October 30 in the United Kingdom and other countries, but the later date began in the U.S. in 2007. The U.S. Energy Policy Act of 2005 changed the start of DST to the second Sunday of March from the first Sunday of April, and extended the end date by one week.

But why? What is Daylight Savings, and why do we have it?

As featured on I-Am-Bored, this lengthy but surprisingly educational video takes you through the history of DST, first proposed by proposed by George Hudson in 1885 to give people more sunlight in the summer. The narrator covers the confusion the hour gained/lost causes as well as modern debates that suggest technology (air conditioning, TVs, video games, smartphones) has outgrown our need to continue changing our clocks.

Some studies say DST now costs more electricity with the hour change, while others suggest it saves — but both agree that the difference is minimal, costing or saving less than 1 percent (or $4) per household.

Perhaps the most interesting thing you may learn is that most of the world does not make any changes to their clocks all year long and two states in the U.S. also don’t recognize Daylight Saving Time. According to the video, Arizona and Hawaii ignore the clock change due to excessive year-round sunlight. The same is true for the U.S. territories of Puerto Rico, the Virgin Islands, American Samoa, Guam, and the Northern Marianas Islands.

And lastly, did you know that “Daylight Savings” is technically called Daylight Saving Time, without the plural? Crazy!
