You know the drill: Spring forward, fall back.
What you might not know is that this Sunday, March 9, is the day determined by the federal government as the day for Daylight Saving Time to kick in. During DST, clocks are turned forward an hour, which moves an hour of daylight from the morning to the evening.
Back in 2005, President George W. Bush signed the Energy Policy Act of 2005. This act changed the time change dates for Daylight Saving Time in the U.S. Starting last year, DST began on the second Sunday in March and ended the first Sunday in November.
Many fire departments encourage people to change the batteries in their smoke detectors when they change their clocks because DST provides a convenient reminder.
