Daylight savings time is tardy this year, arriving one week later than usual, on Sunday Nov. 4. The extension is the result of the Energy Policy Act of 2005, to lengthen the daylight-saving time period, starting in 2007.
Among other provisions, the bill attempts to combat growing energy problems by changing the start and end dates of daylight savings time. Delaying the announced time of sunrise and sunset increases the use of artificial light in the morning and reduces it in the evening. It is presumed that more people need evening light than morning light, and energy is conserved if the evening reduction outweighs the morning increase. Despite this theory, however, many question whether daylight saving results in a net energy savings.
Believer or not, next weekend you’ll get that extra hour of sleep.
