Create a Birthdays Calendar

Thanks to Address Book, you’ll never forget a birthday again. That’s because iCal will create a Birthdays calendar for you, so you’ll have plenty of time to pick up a card or present. First you need to add a birthday field to Address Book.
Here’s how:

1. Open Address Book and go to a contact to which you’d like to add a birthday.
2. Pull down the Card menu and choose Birthday from the Add Field option.

The birthdays you add in Address Book automatically appear in iCal if you:

1. Open iCal.
2. Choose Preferences from the iCal menu.
3. Click the checkbox next to Show Birthdays calendar (under the General tab).
