Daylight Savings Time - Interesting Facts

Daylight Saving Time (DST) begins on Sunday, March 13, 2011. The way we refer to time zones also changes. For example, Eastern Standard Time (EST) becomes Eastern Daylight Time (EDT).

But remember, some areas of the United States don’t use DST, such as Arizona, Puerto Rico, Hawaii, the US Virgin Islands and American Samoa.

Benefits of Daylight Saving Time

Despite some concerns, Americans overwhelmingly like Daylight Saving Time. There is simply more sunlight in the evenings to enjoy the outdoors and get things done. Plus, additional hours of daylight can help save energy on a national scale - as much as 100,000 barrels of oil per day according to some estimates.

And brighter is safer. Studies have shown that the DST shift reduces traffic accidents. Additionally, a study by the US Law Enforcement Admin also determined that crime is consistently lower during DST, with violent crimes down as much as 10% to 13%. For many crimes, like mugging, darkness is a factor--so more light in the evening hours reduces these types of crimes.

Cons of Daylight Saving Time

Not everyone benefits from DST. For example, many farmers say that DST has a negative impact on their livestock’s natural schedules. The airline industry also reports that it costs millions of dollars to adjust time schedules - and even then, airlines report numerous problems with international flight connections during the transition time since DST isn’t followed uniformly around the world.

Interesting DST Facts

A man was actually able to avoid the draft for the Vietnam War using a Daylight Saving Time loophole. When he was born, it was just after midnight, DST. When he was drafted, he successfully argued that in his home state of Delaware, standard time - not DST - was the official time for recording births. So he was technically born on the previous date - which had a much higher draft lottery number - and he was able to avoid being drafted.
In September 1999, the West Bank was on Daylight Saving Time, while Israel had switched back to standard time. A group of West Bank terrorists prepared some timed bombs. Unfortunately for them, they misunderstood the time change and the bombs exploded early - killing the terrorists themselves rather than the intended victims, two busloads of innocent citizens.
In the 1950s and 60s, each state and locality was permitted to choose start and end DST dates as they desired. During 1965, Minneapolis and St. Paul - which are considered one metropolitan area - didn't agree on start dates, and for a period of time, these Twin Cities had a one hour time change between them. And on one Ohio to Virginia bus route, passengers technically had to change their watches seven times in 35 miles!
To keep to their published timetables, Amtrak trains cannot leave a station before the scheduled time. So when the clocks "fall back" in the fall, all trains that are running on time actually stop at 2 am - the official time of DST change - and wait one hour before resuming their routes. In the spring, the routes instantaneously become one hour behind schedule, but they just keep going and do their best to make up the time.
Finally, since many electronic devices and computer programs are set to adjust to DST based on the old dates, they may not change automatically on March 13. So, you’ll want to double-check all of your devices and confirm that the time is correct.
