California Will ‘Fall Back’ to Standard Time Sunday for an Extra Hour of Sleep

Daylight Saving Time for 2023 ends at 2 a.m. on Sunday, Nov. 4, in California, with clocks resetting to 1 a.m. Pacific Standard Time.

The change offers an extra hour of sleep. It’s also a reminder to make sure smoke detectors have fresh batteries and that sprinklers aren’t wasting water.

Most of the United States will “fall back” to Standard Time on Sunday. Only Hawaii, most of Arizona, American Samoa, Guam, Puerto Rico and the Virgin Islands do not change with the rest of the country as they are always on Standard Time.

Arizona opts out of Daylight Saving Time as an energy-saving measure for the desert cities of Phoenix and Tucson, while Hawaii and other islands near the equator do not experience large variations in daylight.

The Automobile Club of Southern California warns drivers to be on the lookout for children and other pedestrians, since it will be dark an hour earlier in the evenings.
