Could anybody rectify my time of Birth...???

[navall]

Dear all,

I am asking for birth rectification, because i dont know the exact time birth, acc to my father it was 4.15 pm and he is not 100% sure as it cud be +/-2 min. when time is taken 2 min before i.e 4.13 pm the navamsa lagna changes from Gemini to Tauras, but on the other hand navamsa lagna remains the same even for next 5 min or more.

As the Lagna changes to Tauras, My 7th House of Navamsa and Venus (Karak for marriage) Becomes afflicted by Rahu and Ketu with deb moon there too.

So i request to take a close look to my chart,so that in case of affliction remedies can be done prior to marriage and so on.

My details are: 6may,1985, 4.15 pm Ambala, (76.49E ,30.19 N) India.
