Daylight Saving Time begins at 2 a.m. Sunday, so it’s time to set clocks ahead one hour as the majority of the United States adjusts to an earlier sunrise and a later sundown. All states observe Daylight Saving Time except Hawaii and Arizona (except the Navajo Nation portion of Arizona, which does observe DST across several states), and about 70 nations also observe Daylight Saving Time. The common expression “spring forward, fall back” is a reminder to change the clock forward an hour in the spring and back an hour in the fall, this year beginning Sunday, and ending Sunday, November 3rd. The time change is made at 2 a.m. Most people make the change before bedtime on Saturday. Most cell phones and other electronics will make the change on their own. The time change is also considered a good time to check the batteries in your smoke detectors
