Your birth chart is one of the most precise tools in astrology — but it only works if the time is right. The exact degree rising on the eastern horizon at the moment of your birth determines your ascendant, your house structure, and the entire framework through which every other planetary placement is interpreted.
An inaccurate birth time means an inaccurate chart and also locks you out of many traditional timing techniques for prediction.
Chart rectification is the process of finding that time using the evidence of your life and orking backwards to establish an accurate birth time.
This is detailed, rigorous work. I use a combination of personality profiling, key life event analysis, annual profections, and zodiacal releasing to build a case for your most likely birth time — presenting the evidence clearly so you can see exactly how and why I arrived at the conclusion. The goal is a chart you can trust and work with for life.
Before You Book — Please Check These First
The more information you can bring to this process, the more accurate the result. Before booking either service, please spend some time checking the following:
- Ask parents, grandparents, siblings, aunts, and uncles if they remember anything about the time of day you were born
- Check any baby books or keepsakes your family may have kept - family bibles too.
- Look for your hospital wristband tag — these sometimes record birth time
- Contact the hospital or maternity unit where you were born — some hold records
- Check your birth certificate — in some countries the time is recorded
Even a rough indication — morning, afternoon, evening, middle of the night — can significantly reduce the number of charts we need to compare and improve the accuracy of the result.
Chart Rectification — Day Part Known (up to 6 hour window) — £225
For clients who have a rough idea of their birth time but need to narrow it down. Perhaps you know you were born in the morning, or that it was after dinner. A 5-6 hour window gives us up to four possible charts to work with — a manageable and focused comparison.
What's included:
- Detailed questionnaire sent in advance covering key life dates and events
- One interview call covering personality, relationships, and significant life moments
- Analysis of the shortlisted charts using profection years and zodiacal releasing
- A second call to discuss the shortlist and gather your feedback
- One hour video reading presenting the full evidence and the case for your rectified chart
- Written notes summarising the conclusion
Chart Rectification — Time Unknown — £450
For clients who have no idea of their birth time and have been unable to source any information about it. A full 24-hour window means at least 12 possible charts to generate and compare with even more needed to refine the ascendant degree. This is significantly more work, and a longer process involving multiple stages.
What's included:
- Detailed questionnaire sent in advance covering key life dates and events
- One interview call covering personality, relationships, and significant life moments
- Full personality profile used to identify the most likely rising sign candidates and narrow to a shortlist
- Second call to discuss the shortlist and gather your feedback
- Final comparison of the two most likely charts using profection years and zodiacal releasing
- One-hour video reading presenting the full evidence and the case for your rectified chart
- Written notes summarising the conclusion
The additional investment reflects the volume of research, chart generation, and comparison involved in working from a completely unknown starting point. This is the most thorough version of the service and is priced accordingly. To book this option please book two of this service.

A Note On Outcomes
Chart rectification is not an absolute guarantee of a single definitive answer in every case, however, I have shown a very good level of precision in previous work in cases which have later turned out to be verified by further research on the client's part.
I can't guarantee of course absolute accuracy and if you later turn up a birth certificate and my timing is not correct THERE ARE NO REFUNDS! :) This work is time consuming and there will be an evidence-based analysis that presents a clear case for the birth time that fits the information we have from your lived experience.
In the majority of cases, this produces a chart that clients recognise immediately as accurate. In all cases, it produces significantly more information about your chart than you had before.
Delivery Time
This is a lengthy piece of work, and I'm aiming at a two-week window from booking to completion. If you need it sooner than that for any reason, please check in with me before booking, as my availability can get booked up with standard readings.
