Sunday marks the end of Daylight Saving Time for 2021. Clocks will be set back one hour as of 2am Sunday morning. Originally the first Sunday in April to the last Sunday in October, it’s changed to the second Sunday in March to the first Sunday in November as part of the Energy Policy Act of 2005. Area citizens are reminded to use this time to check their smoke and carbon monoxide detectors to make sure they’re working properly.
