PHOENIX — Most Americans get an extra hour of sleep this weekend when daylight saving time ends at 2 a.m. Sunday, Nov. 1. Most of Arizona will not touch a clock.
Arizona does not observe daylight saving time, so Arizona time stays the same year-round. The exception is the Navajo Nation in northeastern Arizona, which does observe it and will fall back with most of the country.
What does change is how Arizona lines up with the rest of the country. Starting Sunday, Phoenix will be one hour behind Denver and two hours behind the East Coast, and Arizona will no longer match California and the West Coast.
That matters for TV schedules, sports start times and calls with family out of state. Prime-time network shows and many national broadcasts will air an hour later in Arizona than they did over the summer.
The U.S. first adopted daylight saving time in 1918 during World War I to save fuel, according to the Congressional Research Service, as cited by CBS News. Congress later let states decide whether to observe it, and Arizona opted out decades ago, in part because extra evening daylight in the desert heat was seen as a burden rather than a benefit.
Daylight saving time will return for most of the country in March.
