2007 Daylight Savings Time Changes

February 23, 2007 :: John Mulhern III, ISC Technology Support Services

Beginning in 2007, Daylight Saving Time (DST) has been extended by four weeks. It will begin on the 2nd Sunday of March (March 11th) and end on the first Sunday of November (November 4th). This change will have an impact on many computer operating systems and on calendaring software.

Microsoft and Apple have released patches for their more current operating systems that account for the new DST rules. In addition, most calendar software products have patches to correct for the new DST rules. For more information, please see: http://www.upenn.edu/computing/product/dst2007.html.
