Daylight Saving Time ends at 2 a.m. on Sunday, Nov. 4.

Remember, you’ll “fall back”--set your clocks back one hour before you go to bed Saturday night. Many electronic devices automatically adjust when Daylight Saving Time begins or ends.

What will you do with that extra hour?

When you change your clocks in the fall and spring ÷because of Daylight Savings, it’s also a good time to change smoke detector batteries.

Arizona, Puerto Rico, Hawaii, U.S. Virgin Islands and American Samoa do not observe Daylight Savings Time.

The resumption of Daylight Saving Time will occur on the second Sunday of March, which in 2013 will be March 10.

Change Batteries in Smoke Alarms, Carbon Monoxide Detectors

According to the CDC, ,more than 400 people die every year in the U.S. due to unintentional, non-fire related carbon monoxide (CO) poisoning — something that a fully charged CO detector in a home could likely reduce.

The same is true for smoke alarms. They most often fail because of missing, dead or disconnected batteries so maintenance is a simple, effective way to protect your family and reduce home fire deaths, according to the Washington State Fire Marshal's office.

When you change your clocks, take time to change and test the batteries in your smoke alarms.  

In fact, working smoke alarms nearly cut in half the risk of dying in a home fire. Warnings from smoke alarms can provide those critical extra seconds people need to get out of their homes safely.
