It's a part of the year that usually indicates winter is just that much closer. Daylight Saving Time ends at 2am Sunday November 1, which for this year means turning the clocks back on Halloween night before going to bed.
According to timeanddate.com, “In the U.S., Daylight Saving Time – or “fast time”, as it was called then – was first introduced in 1918 when President Woodrow Wilson signed it into law to support the war effort during World War I.”
For modern times the website notes “In the United States, DST caused widespread confusion from 1945 to 1966 for trains, buses, and the broadcasting industry because states and localities were free to choose when and if they would observe DST. Congress decided to end the confusion and establish the Uniform Time Act of 1966 that stated DST would begin on the last Sunday of April and end on the last Sunday of October. However, states still had the ability to be exempt from DST by passing a local ordinance.
The U.S. Congress extended DST to a period of ten months in 1974 and eight months in 1975, in hopes to save energy following the 1973 oil embargo. The trial period showed that DST saved the energy equivalent of 10,000 barrels of oil each day.”
In 2005 Congress changed Daylight Saving Time to begin on the second Sunday of March and end on the first Sunday of November.
In a CNN article about what daylight saving time does to the body, the recommendations to deal with the change are: Don't stay up late, use the sun and take your time.
Daylight Saving Time 2016 (Spring Forward) begins at 2am Sunday March 13.
