When is it?

We spring ahead the second Sunday in March. This year the time change starts on Sunday, March 13 and ends Sunday, November 6. Not all states observe the time difference: Hawaii, most of Arizona, American Samoa, Guam, Puerto Rico, and the Virgin Islands opt out.
Why do we have daylight saving time?

The hope is that we save energy -- since there's less of a need to switch on the lights if natural light will do. Studies have shown the electricity conserved on the new schedule is actually pretty nominal. But look on the bright side. Those longer light-filled days are sure nice. Searches on the time switch have increased 797% in the last week. The sunlight-deprived would like to know "what is daylight saving time," "daylight saving time dates," and "origins of daylight saving time."
