Daylight Savings Time 2010, the setting forward of clocks occurs at 2 a.m. on Sunday, March 14. By Federal law, daylight savings time changes are set for the second Sunday in March and the first Sunday in November.
George Vernon Hudson, a New Zealand entomologist, first proposed daylight saving time in 1895 as an effort to reduce the use of incandescent lighting.
Prior to 2007, the dates were the first Sunday in April and the and the last Sunday in October. The change to March and November, lengthening daylight saving by about a month, was part of an energy bill passed in 2005 to reduce energy consumption.
States are not required to follow the daylight saving law, Arizona and Hawaii stay with standard time year round, as does Puerto Rico, the Virgin Islands, American Samoa and Guam.
If you cannot remember whether to set your clocks ahead or back, remember "spring ahead, fall back"!
