When you don’t know your time of birth or suspect it is off by a few minutes or more, you can have your birth time rectified. Rectification is a very time-consuming process that involves forecasting backwards in your life and adjusting your birth time until it coincides with all the significant events in your life.
It can be a costly investment. However, the time and costs can be considerably less if you have a birth time on your birth certificate from which to start the process, and if you have a very good memory for as many events in your life as possible.
Rectification is not a job for an amateur; not even all professional astrologers are up to the task. But, for astrology to work properly, an accurate birth time is essential, and rectification is the best way to determine it. So if you want to get your chart rectified, start by obtaining a copy of your birth certificate and then make a detailed list of all the significant events in your life (e.g., births, deaths, relocations, marriages, divorces, career moves, etc.), asking your friends and family members for help along the way if you can't remember exact dates, times or places. After you've done all of this preparatory work, you can start looking for an astrologer who is experienced in rectification.
Rectification is an important investment for anyone who regularly uses and relies on astrology for guidance in life. Once your exact birth time has been properly determined, you will find that astrological consultations are far more accurate than you ever imagined possible, and that the predictive advice you receive will be right on the money.
