Daylight Saving Time ends in the US on November 4, at 2:00 AM in your respective time-zone. Fire departments across the country recommend that you change the batteries in your smoke detectors at this time, because it provides a convenient, twice-yearly reminder to do that, and because properly operating smoke detectors save lives.
Some people refer to the summer time shift as "Daylight Saving(s) Time", which is incorrect. The word "Saving" is used an adjective. It describes what we are doing with "time"; namely that we are saving it. In other words, Daylight Saving Time is the kind of time that saves daylight.
Not that it actually "saves" daylight; rather it moves a little daylight from morning to evening, but nobody is proposing we call it a more appropriate name, like "Daylight Moving Time", or "Daylight Shifting Time" or "More Daylight Up In The Evening Time".
Nevertheless, many people feel that it sounds better to call it "Daylight Savings Time" so they arrogantly and purposefully call it that without regard to whether it is correct. Other people do it out of ignorance, the same way I hear people say "eckspecially", or "assumably". Arrrgh!
But I digress.
