But for getting only one name and change in dob you need to file a declaration suit against the authorities 

1.The right procedure is getting a notice published in a local News Paper, regarding your intention to change your name/or add surname to it, and subsequently get it published in Gazette of India.
These days Gazette prints have been discontinued, so you may have to check with concerned press in your city, if they still print the Gazette Notification, or it is given to you in soft copy.

2.You have to make an affidavit mentioning the correct date of birth before the first class Metropolitan magistrate of your jurisdiction you have to also mention the wrong date of the date of birth.. then have to produce the affidavit before the concerned authority ..

1. The name can be changed by executing a sworn affidavit before an oath commissioner and then publishing it in a national and regional daily. Thereafter, she can change the name in all her documents of identity.

2. However, to change the DOB now will be a long drawn process with an uncertain result. Since 23 March is her DOB appearing in all her documents she has to produce some documentary evidence which will vouchsafe that she was born on 22nd March.

Changes cannot be done simply by notarized affidavit. The legal procedure can be discussed in consultation.

Dear Sir/Madam,

However, it is possible to go for the name change but the same can't be done for the date of birth. For the name change, get the affidavit prepared, news paper publication done and then gazette notification.  

Now cannot change.

Only if you have hospital records which show date and time of 22 march than DOB in BC can change. Spelling of name will change by applying at collector office, Gazette notification will issue.

1. No, she cannot make these changes just by notarized affidavit.

2. She can change her name only and that is only by proper procedures of name change through gazette notification.

3. She cannot change her DOb without her birth certificate and for that she may have to file suit for mandatory injunction against passport office and other departments.

1) Change of name can be done, through Affidavit, and the same needs to be got published in news papers about change of name, followed by publishing in Gazette.  

Further, the same has to be changed in all the certificates also

2) Change of DOB is not possible through Affidavit. 

An application has to be filed before court by giving reasons, if it is captured as 23rd March in Birth Certificate, it is difficult to get it changed.

The name can be changed but not the date of birth. It is too late for that.
