Although this is a bit late for you but Ministry of External Affairs has recently issued a notification announcing an amendment to proof of birth and other rules. The official release is here.
From the release (emphasis mine):
It has now been decided that all applicants of passports can submit any
one of the following documents as the proof of DOB while submitting the passport application:(i) Birth Certificate (BC) issued by the Registrar of Births & Deaths or the Municipal Corporation or any other prescribed authority whosoever has been empowered under the Registration of Birth & Deaths Act, 1969 to register the birth of a child born in India
(ii) Transfer/School leaving/Matriculation Certificate issued by the school last attended/recognized educational board containing the DOB of the applicant
(iii) PAN Card issued by the Income Tax Department with the DOB of applicant
(iv) Aadhaar Card/E-Aadhaar having the DOB of applicant
(v) Copy of the extract of the service record of the applicant (only in respect of Government servants) or the Pay Pension Order (in respect of retired Government Servants), duly attested/certified by the officer/in-charge of the Administration of the concerned Ministry/Department of the applicant, having his DOB
(vi) Driving license issued by the Transport Department of concerned State Government, having the DOB of applicant
(vii) Election Photo Identity Card (EPIC) issued by the Election Commission of India having the DOB of applicant
(viii) Policy Bond issued by the Public Life Insurance Corporations/Companies having the DOB of the holder of the insurance policy
In the same press release point 3.(ii)
says that Annexure A has been withdrawn. Additionally (though this does not directly affect you) all annexes now can be submitted as self declaration on plain paper (Point 3.(iii)
). Please note that ration card is no longer a valid proof of address or identity (I can’t find a direct link to this but the passport homepage has this item in the ticker on top of the page.
If you still haven’t lodged the application, you can submit any of the above documents (as long as they mention the date of birth of applicant) as proof of date of birth.
