I think this is a fantastic idea eden
I've updated it up to this point including my May 31 birthday (May seems to be the biggest birthday month so far!) I really hope you didn't mind us helping update it, if you don't just tell me and I won't do it again, it's just that I had a rare day off work and was a bit bored
Also, I wasn't sure what you wanted to do with multiple birthdays on the same day... for now I've given them a separate line, but I didn't know if you wanted that or them all put on the same line. I'll leave that to you to do what you'd like with it.
