About This Calculator
What it does: This calculator helps narrow an uncertain birth time by comparing the chart against life-pattern clues and rectification signals. How it helps: It gives you a more reliable starting point for later KP analysis when the recorded time is missing, approximate, or clearly unreliable. How to use it: Enter the known birth details, choose the rectification inputs that match the person’s life history, and compare the likely time results or scores shown below.
Need a human check on the scan?
Rectification gets you close, but a live review is still useful when the birth record is ambiguous or the event history is thin. Book a consultation if you want the result checked carefully.
