Daylight saving ends 2013 this weekend. The majority of Americans will adjust their clocks back one hour at 2 a.m. Sunday, Nov. 3 -- allowing slighter lighter mornings and darker evenings at an earlier hour.
Not all U.S. states participate when daylight saving ends. As National Geographic notes, Arizona, Hawaii with the exception of Navajo Indian Reservation residents, Puerto Rico, the Virgin Islands, American Samoa, Guam, and the Northern Marianas Islands.
Daylight saving time is no longer a practice of Russia. They stopped the ritual in 2011. Japan hasn't observed it in over 60 years. Parts of Brazil will turn their clocks back.
When daylight saving ends, it's a good time to hange batteries in warning devices, such as smoke detectors and hazard warning radios. Carbon monoxide detectors are another device that should have fresh new batteries replaced.
Cleaning smoke detectors is a smart thing to do since dust can prevent them from working properly.
