It’s been five years since the Daylight Saving Time rules changed in the United States. In 2007, Congress decided to keep the country on Daylight Saving Time a bit longer, citing energy savings. Whether it actually saves energy or not is somewhat controversial. But at any rate, instead of being adjusted on the the first Sunday in April, clocks are now adjusted for Daylight Saving Time on the second Sunday of March. And for the return to standard time, clocks are now adjusted on the first Sunday in November instead of the last Sunday of October.
Some newer clocks adjust for the time change automatically — in fact some are set to the atomic clock in Boulder, Colorado via a small radio receiver. However, if you bought one of these new-fangled clocks before the rules changed in 2007, it changes automatically — on the wrong date. These sometimes have to be manually set.
Older and more manual clocks also have to be set manually. Although the change actually happens at 2 AM, most people will set their clocks back one hour before they go to bed on Saturday night.
Again, don’t forget to “fall back” one hour on Saturday night.
