It’s Time To Fall Back An Hour in the US and Canada: Daylight Saving Time Ends This Sunday

Yes, it’s that time again if you’ll pardon the pun, to fall back in much of the Northern Hemisphere.

Daylight saving time ends at 2:00AM local time on Sunday, November 7, 2010, in much of the U.S and Canada, except in parts of the countries (including Hawaii and Arizona). You can read more than you’ll ever want to know about DST here and on our official Microsoft Daylight Saving Time Help and Support Center at http://www.microsoft.com/time.

This year, DST in much of the US and Canada ends in accordance with the US Department of Energy’s Energy Policy Act of 2005 that was passed into law. DST will end later than it did prior to 2007, on the first Sunday of November (in 2010, November 7); more details on the new DST start and end times can be found here). This results in a new DST period that is approximately three to four weeks longer than in previous years.

The switch to daylight saving time also means the time zone suffix changes, now using Daylight Time: for example, Pacific Standard Time is now Pacific Daylight Time (aka PDT). The other time zones move to Mountain Daylight Time (MDT), Central Daylight Time (CDT), and Eastern Daylight Time (EDT).

As I noted in this article, Microsoft strongly recommends that DST and time zone updates be installed on all affected systems, devices and applications to ensure consistency with current DST rules and time zone settings worldwide. Customers should review the product updates available and posted on this site and at http://support.microsoft.com/gp/dst_prodlist for the latest and updated information of Microsoft products affected by daylight saving time.
