The mornings will be a little brighter but say goodbye to seeing the sun after work for a while. Daylight saving time officially ends at 2 a.m. tomorrow. Clocks need to be set back one hour unless they are connected to a network like a cellphone.

It is also a good time to check the batteries on all smoke and carbon monoxide detectors.

Daylight saving time has been in place in the United States since 1918 to conserve fuel during World War I. Only Arizona and Hawaii do not conform to the “changing of the clocks.”
