It's time to fall back
Fall back -- it's time to change clocks again.
Daylight Saving Time is a week later again this year, and Halloween skies were lit an hour longer because of it.
Clocks will change at 2 a.m. Sunday -- the first Sunday in November -- rather than the last Sunday of October.
The Energy Policy Act of 2005 is responsible for the change, expanding Daylight Saving Time by a month, starting three weeks earlier and finishing a week later.
For nearly 20 years, Daylight Saving Time lasted from the first Sunday in April to the last Sunday in October.
But in an effort to save energy, that period was extended by a month -- three weeks in the spring and one week in the fall. The government says doing so could save the equivalent of 100,000 barrels of oil a day, but that has yet to be proven.
Not everyone likes Daylight Saving Time. The most frequent complaint is the inconvenience of changing clocks and the adjustment to a new sleep schedule.
Many fire departments use the occasion to encourage people to change the battery in their smoke detectors when they change their clocks.
Daylight Saving Time for the U.S. is not observed in Hawaii or in the state of Arizona, except for the Navajo Indian Reservation, which does observe due to its large size and location in three states.
