The Rectification (Change Birth time) tool offers you a brilliantly simple solution to birth time rectification. It allows you to examine the effects of a different birth time, in any screen, by simply clicking on one of the buttons. Instantly the screen is recalculated and you can observe and judge the effect it has on the horoscope.
This tool will work in the worksheet, the dasha effects window, the rectification screen etc.
Another helpful feature is the rectification screen. This screen gives an overview of different times of birth and how, for each time in the list, the dashas would have been for the events entered. The events are specified for the person’s life. Glancing up and down the list, one can locate that time of birth for which the dasha combinations make sense for each event.
