Correction in Date of Birth in 10th Passing certificate after 16y

The issue is related to correction of Date of Birth on SSC passing certificate (March 2000). I had appeared for SSC examination in Maharashtra in March 2000. My correct date of birth is 14/04/1985 which correctly mentioned on Birth certificate, PAN card, Aadhar Card. However the leaving certificate issued by my secondary school mentions incorrect date of birth which incidentally continued in leaving certificate after 10th and after 12th and also in SSC passing certificate. Now I have applied to one of the Central Govt. for job. They are considering birth date mentioned on SSC passing certificate or leaving certificate only, which would pose difficulties to me in future. Please consider following : 1. I have heard that DOB on SSC passing certificate can be corrected within 10 years. 2. I read in rules of Maharashtra state board that only if DOB in school records is correct and DOB on SSC certificate is wrong then they would do the correction after making application to them through school head. 3. But in my case DOB in school records itself is wrong how ever in my school primary GRN my date of Birth is right but while transcripting in to secondary school certificate it was enterend wrong and then that wrong date of birth continued. Kindly let me know how to rectify date of birth from 10th passing certificate as it is clerical mistake only.Even I went to vashi board for rectification but they told me your school can do whatever can be done we have entered the Date of birth which School provided and then i Went to school they told me to attach only affidavit by court let me know what to do Also kindly let me know the suitable course of action/procedure to be undertaken to : 1. Correct the DOB in SSC passing certificate.
