  • Daylight Savings Time: What is the point of this?


    Hopefully, most of us remembered to turn our clocks back one hour and our clocks reflect the correct time. We enjoy this change of the clock because we get an extra hour of sleep. (WOO HOO!)

    But can someone honestly explain why we do this? And does everybody do this? You've got questions, we've got answers:

    The history behind DST:

        * The Standard Time Acts of 1918 began our clock changing. It was repealed a year later, but re-established in World War II.

        * The Uniform Time Act of 1966 provided dates of the beginning and end of daylight time in the U.S. The act provided that daylight time begin on the last Sunday in April and end on the last Sunday in October, with the changeover to occur at 2 a.m. local time.

        * During the "energy crisis" years, Congress enacted earlier starting dates for daylight time. In 1974, daylight time began on January 6th and in 1975 it began on February 23rd.

        * In 1986, a law was passed that shifted the starting date of daylight time to the first Sunday in April, beginning in 1987. The ending date of daylight time was not subject to such changes, and remained the last Sunday in October.

        * The Energy Policy Act of 2005 changed both the starting and ending dates. Beginning in 2007, daylight time starts on the second Sunday in March and ends on the first Sunday in November.

    What a mess right? And for what? I found these reasons online.

        * It shifts summer daylight to evening hours, when it can be enjoyed more. I think this is a good reason.

        * It saves energy, because people don’t use their lights as much in the evening. Back when lights were the main use of energy, I think this was a bigger justification.

        * It reduces accidents, because people are less likely to be driving in the dark. Hm.

    And remember, Not all places in the U.S. observe daylight time. Hawaii and most of Arizona do not use it.

    My head is spinning.

    What do you think about DST? Do you think its useful or pointless?
