Family Birthday Tracker

Does anyone else have such a hard time remembering the date of everyone's birthday?  Do you think it is such a hassle to rewrite all the birthdays on the new calendar every year?  The new website Pinterest has some wonderful ideas to help just about anything you could possibly want to look up.  I found some ideas to make a birthday tracker.  Thanks to all of the talented crafters who share ideas and get that creative juices flowing in others.  Here is the one that I made and have hanging in the She-Cave as a reminder of who needs a card this month and who I need to plan for next too.
