Get ready to set those clocks forward one hour before going to bed Saturday, as Daylight Saving Time begins Sunday. Daylight Saving Time begins at 2 a.m. on the second Sunday of March and ends at 2 a.m. on the first Sunday in November.

Many fire departments encourage people to change the batteries in their smoke detectors when they change their clocks because Daylight Saving Time provides a convenient reminder.

More than 90 percent of homes in the United States have smoke detectors, but one-third are estimated to have dead or missing batteries.
