Antra and Bhukti. With these many events tally and helps in preparing a right horoscope, but when they do not tally, birth rectification of time is required for the horoscope.

An astrologer can understand if the time difference is much or not and on the other hand, it is also the duty of the native to find some correct ascendant to cast a perfect horoscope. The happening of some particular event has to be highlighted to the astrologer so that he applies the ruling planets theory for Birth rectification time calculation.

Specifying the day, year and month of birth with approximate time is enough to arrive at your birth time.

As the events tally, one can consider that the horoscope is correct, but in case, they fail to tally, then certainly it is incorrect and requires birth rectification of time.
