Birth Time Rectification Tool

Unsure of your exact birth time? Auto-Rectify tests candidate times against real, dated events from your life — and disqualifies any candidate whose own chart denies an event that actually happened.

What this tool does

Birth Time Rectification narrows down an uncertain birth time using events you know actually happened — a marriage, a job change, a health event, a relocation. You provide your recorded (approximate) birth details plus a handful of real, dated life events, and Auto-Rectify tests candidate times around your recorded time, scoring each one on how well it explains what actually occurred in your life.

Full method explained in Birth Time Rectification in KP Astrology.

Who it's for

• Anyone whose recorded birth time is a rough estimate (birth certificate missing exact minutes, family recollection, etc.).
• Anyone who's noticed predictions from their birth chart don't match their real life — a classic sign the birth time itself needs correcting.
• KP practitioners running a structured rectification workflow instead of manual trial-and-error.

How it works

1. Enter your name, recorded (approximate) birth date, time and place.
2. Add a few real, dated life events — the more specific and confidently dated, the better the result.
3. Auto-Rectify generates candidate times around your recorded time (typically within roughly ±5 to 30 minutes), scores each against your events using dasha-period timing, and independently checks each candidate's own Cuspal Sub-Lord promise for that event category.
4. You get a ranked shortlist with confidence scores, a timeline showing which events each candidate explains, and a side-by-side comparison against your original recorded time.

What makes this different

The distinguishing piece is the CSL Promise Cross-Check: a candidate time that matches your events purely on dasha timing coincidence is still disqualified if its own natal Cuspal Sub-Lord structurally denies that category of event. A candidate time can't contradict its own chart — that's the same standard classical KP rectification practice expects, and it's built into every rectification run here, not offered as an optional extra check.

Choosing good rectification events

The method works best from events you can date with real confidence: a wedding date, a job start date, a hospitalization, a relocation, the birth of a child. Vaguer memories ("things felt hard around 2015") don't give the scoring enough precision to discriminate between candidate times, so a shorter list of well-dated events consistently outperforms a longer list of fuzzy ones.

What the output looks like

A rectification run returns a ranked shortlist of candidate birth times with confidence scores, a timeline showing exactly which of your events each candidate explains and which it doesn't, and a side-by-side comparison of cusps, sub-lords and dasha timing between your original recorded time and the top candidate — so the correction is never a black-box number, you can see precisely what changed and why.

The traditional definition of "birth"

Classically, the moment used for a chart is the baby's first cry — the first independent breath — not the moment delivery began or the time written on a certificate, which can lag the actual moment by several minutes. If you have that precise moment from a reliable source, use it as your starting point; if you only have a rough estimate, that's exactly the gap this tool is built to close.
