Keeping track of birthdays can be difficult, especially when you come from a sizable family and then marry into an even more sizable family. Between my parents, my siblings and their kids, there are 21 of us. Combine that with 35 people on my husbands side and I have 56 birthdays to remember. Plus 3 Grandparents and a handful of friends. So I started searching for a system that would aid my memory, and I pleasantly stumbled upon this free printable Birthday Calendar at Lemon Squeezy. I really like that everyone's birthdays are displayed on one page. With a single glance I can see who's birthday is this month and how many cards I will need to get for next month. It will make planning ahead a cinch and hopefully I won't miss any more birthdays!
