The date displays incorrectly in the Windows Calendar Sidebar gadget on a Windows Vista-based computer

When you add the Windows Sidebar Calendar gadget to the desktop of a Windows Vista-based computer, you may notice that the date displays incorrectly in the Windows Sidebar Calendar gadget.

Note Although the Windows Sidebar Calendar gadget shows the incorrect date, the system clock still shows the correct date.

This problem will occur if the following conditions are true:

• The computer is set to use a time zone in which the daylight saving time change starts at midnight, such as the "(GMT-3:00) Brasilia" time zone.
• In the Time Zone Settings dialog box, the Automatically adjust clock for Daylight Saving Time check box is selected.

This issue occurs because of an error in the Windows Sidebar Calendar gadget.

If the change to daylight saving time occurs at midnight, the Windows Sidebar Calendar gadget adds a second instance of the previous day to the calendar when the Automatically adjust clock for Daylight Saving Time check box is selected. Additionally, all the remaining days for that month appear one day ahead.
