Daylight saving time ends at 2 a.m. this Sunday, so you'll need to remember to turn your clocks back one hour before you go to bed Saturday night.
It also marks the 25th year that the International Association of Fire Chiefs has used daylight saving time as a time to remind people to change the batteries in their smoke alarms and carbon monoxide detectors and test them to be sure they're working.
"Eighty percent of child fire fatalities occur in homes without working smoke alarms," St. Petersburg Fire and Rescue fire marshal Robert Bassett said in a prepared release. "It's a tragic statistic that could be reduced by adopting the simple habit" of changing batteries and performing tests twice a year.
This was the sixth daylight saving time period since federal changes to daylight saving time set it to begin at 2 a.m. on the second Sunday in March and end on the first Sunday in November. The change, required in 2007 by the 2005 Energy Policy Act to reduce energy consumption, marked the first adjustment of daylight saving time dates in 20 years, according to the National Institute of Standards and Technology.
