Hi

Two different dobs which is the right one?

Valid proofs of date of birth for most of the exam forms are 10th marksheet and aadhaar card. Now I hope the dob in your aadhaar card is the right one or if its not then change it. UIDAI has

given direct link — ssup.uidai.gov.in/ssup/login.html for Aadhaar card holders who wish to change their date of birth. Just upload supporting documents and its done!

Changing the dob in 12th mark sheet is comparatively more complicated that entirely depends on your board of education!

Aadhaar card is an accepted valid proof of address and date of birth in India. So make sure to correct any errors in it.

Hope this helps.
