Facebook's birthday reminders enable thousands of birthday greetings every day. Whether a message, a Wall post, a greeting sent through applications like Birthday Cards, Birthday Calendar, and Birthday Greeting Cards, or an old-fashioned phone call, people have found it easy to keep track of their friends' birthdays thanks to a little box in the right hand column of the home page.

To make it even easier—even if you don't check Facebook every day—this week we released a new feature that can remind you of upcoming birthdays via an email notification. If you opt in, you will receive an email on the weekend summarizing the upcoming birthdays of your friends for the next week. Here is how to enable it from the Account Notifications page:

1. Under the "Facebook" section, click "Show More"
2. Turn on "Has a birthday coming up"
