TOLEDO, Ohio – Daylight saving time ends this year on Sunday, Nov. 3 at 2 a.m., sending clocks back an hour and giving everyone that extra hour of sleep they lost in March. The biannual event is observed by 48 states, the only two opted out on a loophole being Hawaii and Arizona. However, legislative efforts in many states support the permanent establishment of daylight saving time. But even state bills that pass would not be allowed to take effect until Congress repealed the federal law mandating the current functionality of daylight saving time.
