How would friends react when they find out I changed my birthday on Facebook?

[M.C.]

I've had the account for 2 years now. When I first created one I set up a fake birthday only the birth day was true but the month was false. I don't know why I did but I did. Year after year friends post and wish me happy birthday but i forgotten I added family members from England so they are puzzled and they wrote out the confusion on my timeline. Now I want to change it to the true month but would facebook allow it?? I'm 16 and i remember I couldn't change it so easily. But could I now?! And if I do change it how wod many of my fb friends react to this?

They'd most likely ask you why the hell you put your fake birthday and why you didn't tell them sooner. Depends on your friends, actually. Maybe they'd be a little pissed. Maybe they'd laugh and call it a joke, you should know your friends the best.
