Well, I don't know about this, and I never thought about it. This comes to my mind when I read your post, I don't even know the birthdays of my previous companies, and I don't remember the birthday of my own business. I suppose I can check it on my business license.

Very interesting question. But don't think that we have the exact answer. You may try to ask the admins if you're really curious and if the information holds some value to you. I tried to search for an answer. But in vain. Good luck to you!
