Time Zones & Daylight Saving Time
Daylight Saving Time in Canada - changes for 2007
Starting in March 2007, the standard North American period for Daylight Saving Time is to be from the second Sunday of March to the first Sunday of November. For more information on how this can affect computers, click here.
Canadian provinces and territories have announced that this standard will replace their previous practice (from 1987 to 2006, DST was from the first Sunday of April to the last Sunday in October).
Note that for 2007, the time difference between Europe and North America will change for a period of 3 weeks instead of 1 week (2 weeks in March and 1 week in November) and will be in the opposite sense to past experience.
