OL2000: Birthday or Anniversary Spans Two Days

In Microsoft Outlook, some anniversaries, birthdays, and other recurring all-day events such as holidays, may appear in the Calendar on two consecutive days.

Outlook treats anniversaries and birthdays as all-day events. If you change the Windows time zone after you create an all-day event, the event may span two days instead of one. If you change the time zone back to the one in effect when the anniversary or birthday was created, the all-day event reverts to the correct time and spans one complete day.

All Outlook calendar events are sensitive to the change of time zones.

To work around this problem, either correct each item for the current time zone setting, or change the time zone in Windows back to the one used when the items were created.

NOTE: In the daily view of the Calendar, a clock icon appears on the item. If you open such a recurring item, the appointment dialog box specifies the time zone of the appointment.

Correcting Each Item for the Current Time Zone

To change each birthday or anniversary back to a single day, follow these steps:

1. Open the recurring item in the Calendar. When prompted, click Open The Series.
2. Click the Recurrence button on the toolbar.
3. Verify that all settings in Appointment Recurrence are correct and then click OK.
4. Click Save and Close on the toolbar.

Changing the Time Zone

To change the time zone in Windows back to the one used when the items were created, follow these steps.

1. Open the recurring item in the Calendar. When prompted, click Open The Series.
2. In the appointment dialog box, under Recurrence, note which time zone defines the item. On the File menu, click Close to close the appointment without saving.
3. On the File menu, click Exit And Log Off.
4. Click Start, point to Settings, and then click Control Panel.
5. In Control Panel, double-click the Date/Time icon.
6. On the Time Zone tab, click to select the time zone that matches the one in the Outlook appointment, and then click OK.
