Birth time rectification
Work back from dated life events. The narrower the time range and the more events you add, the more precise the result.
Guide
How to use birth time rectification
Rectification tests candidate birth times against dated life events to narrow the range. The result is an estimate, not a substitute for an official birth record.
Good for
- Narrow the range when you only know your approximate birth time
- Compare how different Ascendants and Midheavens fit life events
- Settle on a working birth time for future natal chart readings
How it works
- 1Enter your birth date, place and the most reliable time range you have.
- 2Add at least 4 major life events with reliable dates.
- 3Compare the candidate times and how well each fits your events, keeping the uncertainty in mind.
Frequently asked questions
Is the result my exact birth time?
No. It's an estimate based on your events and the model's rules. Cross-check it with family memories or a birth certificate.
Why do I need several life events?
One event can match by chance. Several well-dated events of different kinds show which candidate time holds up.
Which events work best?
Moves, school milestones, career changes, major relationships or family changes: events with fairly clear dates that had a real impact on you.
