Time Change Spring 2010 will begin on Sunday, March 14, 2010 at 2 a.m. in the United States. Every spring we move our clocks 1 hour ahead of time in order to adjust for the time change. When it is fall we "lose" an hour during the night and each Fall we move our clocks back one hour and "gain" an extra hour.
But Daylight Saving Time (and not Daylight Savings Time with an "s") wasn't just created to confuse our schedules. The phrase "Spring forward, Fall back" helps people remember how Daylight Saving Time affects their clocks. At 2 a.m. on the second Sunday in March, we set our clocks forward one hour ahead of Standard Time ("Spring forward"). We "Fall back" at 2 a.m. on the first Sunday in November by setting our clock back one hour and thus returning to Standard Time.
The change to Daylight Saving Time allows us to use less energy in lighting our homes by taking advantage of the longer and later daylight hours. During the eight-month period of Daylight Saving Time, the names of time in each of the time zones in the U.S. (map) change as well. Eastern Standard Time (EST) becomes Eastern Daylight Time, Central Standard Time (CST) becomes Central Daylight Time (CDT), Mountain Standard Time (MST) becomes Mountain Daylight Time (MDT), Pacific Standard Time becomes Pacific Daylight Time (PDT), and so forth.
