How does daylight saving time work in March? What to know about time changes as we prepare to spring forward.

Daylight saving time ends this year in the early hours of Sunday, March 10, giving us longer, sunnier evenings until Nov. 3. Here's what to know about how the time change works. 

While the origins of daylight saving time are disputed — ranging from an essay authored by Benjamin Franklin in 1784 to a pamphlet written by British builder William Willet in 1907— the time change itself is standardized. Daylight saving time always begins on the second Sunday of March and ends on the first Sunday of November.
