From Michel Dalal:
Utility to manage and organize family's, friend's and associate's birthdays. Seamlessly integrates with Address Book and iCal. Current features include:
- Integration with Apple's Address Book. A person's information is obtained from your Address Book.
- Ability to add and/or update a person's date-of-birth.
- Gradual highlighting for approaching birthdays.
- Intelligent exporting of birthdays to iCal. However, you do not have to export to iCal to see whose birthdays are approaching.
- If you add/update a person's information, existing events in iCal will be updated to reflect those changes on your next export.
- Ability to move events into other iCal calendars.
