In 2014 we (as in a majority of North America) spring forward one hour on March 9th at 2:00 AM local. That’s just one day shy of the earliest that we can now spring forward, as the current convention established by the Energy Policy Act of 2005 during the Bush administration that was enacted in 2007 now sets the beginning of DST as the 2nd Sunday in March.
In 2005 Congress passed the Energy Policy Act of 2005. One of the provision of the bill was to extend Daylight Saving Time by four weeks starting in 2007. Daylight Saving Time begins on the second Sunday in March and ends on the first Sunday in November. Previously, Daylight Saving Time started on the first Sunday in April and ended on the last Sunday in October.
You may be asking how changing Daylight Savings time ends up in an Energy Bill. In theory Daylight saving times promotes energy conservation. Energy consumption is lowered because we use less energy in lighting our homes by taking advantage of the longer and later daylight hours.
Daylight Saving Time was instituted in the United States during World War I in order to save energy for war production by taking advantage of the later hours of daylight between April and October. During World War II the federal government again required the states to observe the time change. Between the wars and after World War II, states and communities chose whether or not to observe Daylight Saving Time. In 1966, Congress passed the Uniform Time Act which standardized the length of Daylight Saving Time.
The switch will provide an extra hour of daylight in the evening, so the sun won’t set Sunday until 7:04 p.m. But it also will mean that workers and school children who were getting used to getting up to daylight the past few weeks will again arise in the dark. Sunrise will come Sunday at 7:27 a.m.
