From the developer:
BirthdaysPro creates birthday lists, contact lists, and releases birthday notifications. With this utility, you are always informed about the upcoming birthdays of all your contacts. You get up to 2 notifications for each birthday. However, you can switch off the reminder for certain contacts. You can add or edit birthdays directly in the address book or in BirthdaysPro.
You may want to check out more Mac applications, such as PhoneAmego, PastebotSync or ScreenHaven, which might be similar to BirthdaysPro.
