Daylight Savings 2011 – Did you know that Daylight Savings Time ends today? You probably woke up this morning and had to change some of your clocks if you didn’t make the change last night. Make sure to change your clocks back by one hour.
It also means that you get one extra hour of sleep.
In the northern hemisphere, the annual event generally begins in March and ends in November. It allows for more daylight during the evening hours and less in the morning hours. The shift is meant to make mornings lighter, helping people to prevent accidents and wake up to sunlight, rather than to the drizzling darkness that has plagued recent dawns. It was originally introduced to make the most of the weakened winter sun.
The practice has been criticized and reported to cause problems for farming and other occupations tied to the sun and daylight.
In the United States, the Energy Policy Act of 2005 says it officially begins on the second Sunday of March and ends on the first Sunday of November.
Ben Franklin was apparently the first person to suggest the concept of changing the clocks because it was a way to save oil for lanterns.
It wasn’t until World War I that changing the time was realized on a grand scale. Germany was the first state to adopt the clock changes, to reduce artificial daylight and thereby thereby saving coal for the war effort.
