Which spine number coincides with your birthday?

I know this is an odd question and reads a bit like I'm collecting data, but hear me out! My copy of Black God White Devil showed up recently and I noticed that the spine number (1225) was my birthday. So, I looked it up and realized that we have gone past 1231, so everybody has a spine birthday number. I guess some of you have two, if your your birth day is a single digit, but anyone care to share? Nothing datacollecting!

EDIT: I am glad that a random thought I had in the middle of the night has brought so many people joy. To the people saying thanks, you're very welcome. And to the people making the totally fair point that this is American format dating, let's do this again upon the release of spine number 3112!
