The annual “spring forward” for American clocks – well, most American timepieces – arrives at 2 a.m. Sunday, March 10.
Everyone in the United States excluding Hawaii and Arizona participates in the time change. A few territories also pass.
Daylight Savings Time was created to give evening hours more sunshine and to save energy even though later studies proved that the move saved very little energy.
When solidified by the Unified Time Act of 1966, DST was conducted on the last Sunday in April and the final Sunday of October.
In 1986, the early DST date was moved up to the first Sunday in April.
It was extended in 2007 by moving to the second Sunday in March and the first Sunday in November.
If you really like to plan, DST ends November 3 this year – that’s when we’ll “fall back.”
