Hi,

That cannot be changed. Only court can declare your birthday on matriculation certificate & that also you have to produce invincible proof like

(1) the hospital certificate in which you were born

(2) if you were born at home the midwife or the women who helped your birth (she has again to file  affidevit in court).

(3) birth certificate from municipal corporation.

After this with the above documents you have to approach the court and the court will declare your new date of birth. But still then the date of birth on your marriculation will remain as it is. However, after declaration by court your new date of birth shall remain valid for all govt. Records.

Hope you got your answer.
