I have a MacBook Pro intel running 10.6.8
My iCal has started to swap my friend's birthdays about. I have entered them correctly in Address Book, but some (not all) are now just plain wrong in the calendar.
(I have now sent two birthday cards on the wrong dates!)
The date is correct in the system clock.
Any suggestions?
Thanks

Rain,

You might try these steps.

1. In iCal, go to Subscriptions on the left and uncheck "Birthdays"
2. In iCal, go to Preferences in the Menubar
3. Go to General, and uncheck "Show Birthdays calendar"
4. Quit iCal
5. Relaunch iCal
6. Go to iCal Preferences and checkmark "Show Birthdays calendar"
7. Make sure "Birthdays" is checkmarked again under Subscriptions
8. If you do not like the new default color, highlight "Birthdays" and then use Command + i to get "Birthdays" Info. Use the up/down arrows in that window to select the color you prefer.

Thanks for the suggestion, tried it, no luck
