Proponents usually argue that the time change conserves energy by minimizing the need for residents to use electrical lighting at home, because the sun sets one hour later in the evenings. But those on the opposite side of the debate say the practice wastes energy.
"Patterns of energy consumption today versus 70 years ago are so different," said Chu.
In 2008, the National Bureau of Economic Research concluded that daylight saving time actually increases residential electricity demand by about 1 percent, and between 2 percent and 4 percent in the fall. The researchers studied three years' worth of residential electricity consumption data from Indiana households and also concluded that there was a social cost of increased pollution emissions.
States and territories of the U.S. can opt to exempt themselves from observing daylight saving time as is the case with Hawaii, Arizona, American Samoa, Guam, Puerto Rico and the Virgin Islands. In the case of Arizona, most of the state, with the exception of the Navajo Nation, observes Mountain Standard Time year-round.
Another argument for resetting all our clocks — or relying on smartphones to do it for us — is it can save lives and prevent traffic injuries when people are doing errands or traveling to and from work or school during the daylight hours. Additionally, they suggest it can reduce crime since people are out and about during the daytime when there's less crime.
Yet, there may be a health risk associated with the time change. There is a 25 percent jump in the number of heart attacks on the Monday after the time change compared to other Mondays during the year, according to a study presented in 2014 to American College of Cardiology.
A national Rasmussen Reports survey released in 2014 also found that 43 percent of respondents believe there's no need for daylight saving time.
