In 2007, the US moved daylight savings to March 11 instead of the more traditional
first weekend in April.  It continues to November 4, a week later than before.
Google "daylight savings 2007" for lots of background.

Some MS programs did not make the switch until April 1, therefore my calendars
doubled up continuing appointments.
