What calibration is doing, and why we ask first
Before reading forward, Daivaj checks the chart against your past. Here is what those questions test, what the score means, and why a birth time can be corrected.
Most astrology asks you to trust the chart. Daivaj checks it first.
The problem calibration solves
A birth chart is only as good as the birth time behind it. The ascendant moves about one degree every four minutes, and the house placements — which most of a reading rests on — move with it. A time recalled as "around 9pm" can put planets in different houses than the truth, and every reading built on it inherits the error.
Recorded times are frequently wrong. Hospital records get rounded, family memory drifts, and a certificate often records the time of registration rather than birth.
How the check works
Calibration asks about real stretches of your past — periods the chart makes a specific claim about. For each one you say whether the thing it predicts actually happened.
Crucially, some of the questions are controls: periods the chart says nothing about. A chart that predicted everything would agree with every "yes", and a chart that predicted nothing would agree with every "no". Neither is accuracy, so the score measures both directions — how much of what happened it caught, and how much of what did not happen it correctly stayed quiet about. Agreeing with everything cannot produce a high score.
"Not sure" is dropped from both sides. A skipped question is missing evidence, not evidence against.
Correcting the birth time
While scoring, Daivaj also tests candidate birth times around the one you gave — and, if nothing fits, across the whole day. If your life fits a chart drawn a few minutes from the recorded time substantially better than the recorded one, the reading uses the corrected chart.
Your recorded birth time is never overwritten. What you told us stays exactly as you told it. We correct the reading, not your memory.
What a low score means
A low score is information, not a failure. It usually means one of three things: the birth time is further off than the search covered, the birth date or place is wrong, or the periods asked about were ones you genuinely cannot recall.
If nothing verifies at all, Daivaj says so rather than banking the result. An unverified chart still gets read — but it is read tentatively, and the reading tells you it could not be confirmed.
