Dear Client, 

You can't change the date on the birth certificate but you need to execute an affidavit and newspaper publication stating your correct date.

Thank You

You can change the date in all the wrong documents or execute a common notarized affidavit for the same

You cannot rectify the birth certificate to your convenience.

The date of birth recorded in the birth certificate cannot be altered or amended.

If you want to alter or change the date of birth in the register for births held by the competent authority you may have to file a suit for declaration to declare your correct date of birth in the basis of the documentary evidences you rely upon.

If the court is convinced and satisfied by the documents you have produced before court, it may pass an order to declare your correct date of birth and may direct the concerned birth registrar to amend the date of birth accordingly.

 It is possible to correct the date of birth on all documents including passport but the procedure  is cumbersome and time taking. Your best option is obtain a fresh certificate as on date borne by all document. Under Section 15 of the Registration Of Births And Death Act you can also get your date of birth corrected but that is also not easy.

Following is the procedure under Births and Death Registration Act for obtaining birth certificate …

1. Apply to municipal authority for birth certificate as shown in certificate. Municipal authority will give a certificate that no such birth is registered on that date.
2. Submit an application to the Executive Magistrate/Tahsildar/MRO for direction to municipal authority for birth certificate  on the date mentioned in documents with following  .
3. A notarized affidavit stating that you birth took place at home on the said date and the same is not registered.
4. “No birth registered certificate” issued by municipal 
5. Notarized affidavit of mother and father (if alive) stating that you birth took place on that date and it is not registered.
6. First page copy of passport and education certificate of 10th. SSC etc.
7. Executive Magistrate/Tahsildar/MRO will give direction to municipal authority for issuing birth certificate.
8. Take that direction to municipal authority and apply for birth certificate  on said date.
9. You will get required birth certificate on payment of Rs. 50/- fee to municipal 

But in your case there is not big gain. You are getting benefit of 10 days.

Well you can correct the documents using a affidavit or court order if you still wish to proceed.
