Don’t forget to reset your time clocks, timers, generator exercise timers, and building management systems this weekend for the end of Daylight Saving Time. It’s also a great time to check any batteries in your time clocks, smoke detectors, fire alarm, and security systems.

The official time for people to turn the clocks back an hour is at 2 a.m. on Sunday, November 1. You might get an “extra” hour of sleep that day, but it will also begin to get darker earlier in the day. The amount of daylight will shorten each day until the winter solstice on Dec. 21. Daylight saving time begins again March 14, when clocks “spring forward.”
