Richmond, Va. — We fell back to Eastern Standard Time at 2 a.m. Sunday.  It’s also a good time to replace your smoke & carbon monoxide detector batteries.

Here is how it affects the timing of the daylight:

We switch back to Daylight Saving Time (and lose an hour of sleep) on Sunday, March 13, 2016.  The Energy Policy Act of 2005 changed when we switch the clocks.  Since 2007, we switch the clocks on the second Sunday in March (to Daylight Saving Time) and the first Sunday in November.  This extended the amount of time during the year that we observe DST.   Prior to 2007, we used to change the clocks the first Sunday in April and the last Sunday in October.

We use the 2 a.m. time on Sundays because it was originally thought it would be the least disruptive to most people’s lives.  Daylight Saving Time is observed in about 70 countries around the world.  However, in the United States, Hawaii and parts of Arizona do not.
