Daylight saving time came to an end early Sunday morning, Nov. 2, with clocks ‘falling back’ an hour and people across most of the United States getting an extra hour of sleep. Daylight saving time always occurs on the second Sunday of March and ends on the first Sunday of November.

Many Americans will have to reset their clocks and circadian rhythms when daylight saving time ends on Sunday.

A sound extra hour of sleep Saturday night won’t hurt, either.
