PORTLAND — It's the weekend to spring ahead to daylight saving time.
For one night, there's the prospect of 60 fewer minutes of shut-eye, but ahead are many months with an extra hour of evening sunlight.
The official change takes place at 2 a.m. on Sunday.
"This change helps keep the hours of daylight coordinated with the time that most people are active," according to the National Institute of Standards and Measurements. "Proponents feel that this saves energy because in the spring and summer months more people may be outside in the evening and not using energy at home."
Recent studies have shown that people in Indiana may use more energy as a result of DST, and that California might benefit from moving the clocks ahead and leaving them there.
Not everyone in the U.S. makes the switch from standard time. The exceptions are Hawaii, most of Arizona, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas.
Standard time returns this year on Nov. 3.
