The Energy Policy Act of 2005 extended Daylight Saving Time in the U.S. beginning in 2007, though Congress retained the right to revert to the 1986 law should the change prove unpopular or if energy savings are not significant. Going from 2007 forward, Daylight Saving Time in the U.S. (and most of Canada) begins at 2:00 a.m. on the second Sunday of March and ends at 2:00 a.m. on the first Sunday of November.
In most of the countries of Western Europe, including the countries that are
members of the EU, Daylight Saving Time: begins at 1:00 a.m. GMT on the last Sunday of March and ends at 1:00 a.m. GMT on the last Sunday of October
