How do I change an incorrect birth date on my driver's license, social security card and other personal history?

Question Details:

I just recently found out that my birthday is not my birthday. My driver's license, social security number, and personal history does not match my birth certificate. My original birthday is in December and all my documentation has a birthdate of March, 4 months after my birth. How do I go about correcting this and are there any legal issues that I will need to address? I have an expired passport with the correct birthdate that was issued prior to my knowledge of the wrong date. (I thought is was just an error and I only needed to use it once but now I know it was correct). Important Notice
