Boston-area residents and others across the country can look forward to an extra hour of sleep as clocks turn back one hour in observance of daylight savings time at 2 a.m. Sunday morning.
The time shift occurs twice per year in North America: one hour is lost on the first Sunday in April, and the hour is gained back on the last Sunday in October. This policy was enacted by the Uniform Time Act in 1966.
Lawmakers made recent changes that will extend DST four to five weeks beginning in 2007. The Energy Policy Act of 2005 will change DSTs duration from the second Sunday of March to the first Sunday in November. Those in favor of the change said the US will save on energy costs by taking advantage of the extra hour of sunlight during the extended period.
