In 2012, the U.S. switched to Daylight Saving Time on March 11.
The big [push id for folks is to check or replace the batteries in the smoke and carbon monoxide monitors in the house.It is useful to also check that you know whether to move the clocks ahead or behind.
Very often, the beeping coming from a smoke detector is a sign that the batteries may be going dead. If you want the beeping to stop, change the batteries.

To change from Daylight Saving Time to regular time, you typically "fall back" by setting your clocks back one hour. This transition usually occurs in the fall when Daylight Saving Time ends. People in regions that observe Daylight Saving Time usually set their clocks back on the first Sunday in November.
Fire safety officials encourage people to use the two annual clock shifts as a reminder to check the batteries in smoke and carbon monoxide detectors. This is especially important in fall, just before the heating,candle, and fireplace season causes an increase in home fires.
Because they hate change of course..
