When is daylight saving time — and will changing our clocks soon be a thing of the past?

Daylight saving time returns to the U.S. on Sunday and is scheduled to end in early November as usual — unless Congress decides it's time for a change. A proposal to end the decades-old practice of making Americans change their clocks twice a year passed the Senate by unanimous consent last year but wasn't voted on in the House, meaning the legislation must start over in the new Congress.

Under the measure, daylight saving time would have been made permanent, and if the bill was signed into law, most Americans would have shifted their clocks one hour forward Sunday and left them that way. As it stands now, those clocks will need to be shifted back an hour on the first Sunday of November, when standard time resumes.

A CBS News/YouGov poll last year found nearly 80% of Americans supported changing the current system. The idea of permanently shifting an hour of daylight from the morning to the evening appealed to 46% of Americans while 33% wanted the clock to run out on daylight saving time.
