Daylight Savings

As of 2007, Daylight Saving Time begins in the United States on the second Sunday of March and concludes on the first Sunday of November. During the warmer months, clocks are advanced so that darkness falls later.

Daylight Saving Time also changes the names and acronyms used for local time in each zone. Eastern Standard Time (EST) becomes Eastern Daylight Time (EDT), Mountain Standard Time (MST) becomes Mountain Daylight Time (MDT), and so on.
