Well, going back in time might have been terrible for Marty McFly in “Back to the Future,” but for most people setting their clocks back an hour Sunday morning, it will mean another hour of welcome sleep. 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, Daylight Saving Time 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 Daylight Saving Time. Congress decided to end the confusion and establish the Uniform Time Act of 1966.”
Since then, Congress extended Daylight Saving Time to a period of eight months in 1975, in hopes to save energy following the 1973 oil embargo. The trial period showed that Daylight Saving Time saved the energy equivalent of 10,000 barrels of oil each day.” Then, in 2005, Congress changed Daylight Saving Time to begin on the second Sunday of March and end on the first Sunday of November.
Setting the end date in November allowed longer daylight in the evening for tricker-or-treaters on Halloween night in the interest of safety.
