JOINT BASE SAN ANTONIO, Texas -- Daylight saving time ends Nov. 5. Time will be set back one hour at 2 a.m. to standard time.
Beginning in 2007, Congress established that daylight saving time begins on the second Sunday in March and ends on the first Sunday in November.
Before then, daylight saving time dates have varied as Congress passed new statutes several times since the Act of March 19, 1918, sometimes called the Standard Time Act. The act also established daylight saving time, a contentious idea then.
Not all places in the United States observe daylight saving time. In particular, Hawaii and most of Arizona do not.
As you move your clocks back an hour, don’t forget to change the batteries in your smoke detectors and other home safety devices.
Having a working smoke detector can mean the difference between life and death. The death rate is twice as high for home fires where the smoke detectors are either absent or not working, according to a 2019 report by National Fire Protection Association researcher Marty Ahrens.
A smoke detector cannot operate without working batteries, so this Daylight Saving Time is an excellent opportunity to remind yourself to replace the batteries in your smoke detectors at home. In addition, you should test them at least once per month so you know if batteries need to be replaced.
Let the beginning and end of Daylight Saving Time serve as a reminder that when you change your clocks, also change your batteries in your smoke and carbon monoxide detectors. A few minutes could save your life.
