Accurate time of birth : Question for learned members

[Guest guest]

Dear learned members,

Often enough I have seen that astrologers ask for the exact time of birth so

that the prediction can be accurate.

Since astrology is an ancient subject and science, some time back in India, lets

say before 1950, very few people had watches and also very few people were born

in hospitals(which may have had watches and hence time of birth was noted

accurately).

Now we all have watches and can get the accurate time of birth,

 

does it mean that all the predictions that were done earlier than 1950 were hit

or miss since time was not very accurate?

 

[i remember my grandmother saying ... " oh...Aunt was born in Magh month " not

which day and minute]

Excuse me if this is a silly question.

Best

Raj
