Questions
What is birth time rectification?
It is the process of recovering an unknown or unreliable birth time by testing candidate times against events that have already happened in your life, and keeping the one the transits fit best.
Why does my birth time matter?
The ascendant moves roughly one degree every four minutes. Without an accurate time your rising sign, your house placements and the position of the Moon can all be wrong, which affects most of the chart.
What do I need to provide?
Your birth date and place, and at least two dated life events — a move, a marriage, a bereavement, a job change. Events from earlier in your life are the ones most likely to make contact.
Do I see the result before I pay?
You see the window of times your events fit best, how distinctive that fit is compared with randomly made-up dates, and how many of your events aligned. The rectified time itself is the paid part, and it is included free with an Astral membership.
