Clocks are going back an hour this weekend: Daylight saving time is once again ending to create a monthslong window where it’s dark when you leave for work and dark when you’re on your way home. On Sunday at 2am ET, we will turn our clocks back our clocks will reset themselves and our microwaves will either be right or wrong until we move the clocks ahead in March. All this disruption to our lives, and most studies show that clocks going back an hour has a minimal impact on conserving energy.
