The last time Americans changed the clocks in 2014 was on Sunday, Nov. 2, at 2 a.m., when they were set one hour back. This officially ended daylight saving time that had begun on March 9. Clocks were set one hour ahead at that time.
In 2015, daylight saving time officially began Sunday, March 8, at 2:00 a.m., and is scheduled to end on Sunday, Nov. 1, 2015, at 2 a.m. A recent New Mexico bill proposed keeping daylight saving time year-round. Sen. Cliff Pirtle (R-Roswell) proposed the bill, claiming the adverse health effects caused by setting the clocks back outweigh any benefits of daylight saving time. Although the bill passed the New Mexico Senate, it failed in the house. Currently, Arizona is the only state that does not observe daylight saving time, joined by Puerto Rico, Guam, the U.S. Virgin Islands and American Samoa.
