Rectification is the astrological technique of deducing an unknown birth time by comparing a person's known life events and personality traits against multiple possible charts. Practitioners have relied on this method for centuries — long before computers, Vedic astrologers would manually test different ascendants until one chart consistently matched the individual's reality.

Modern rectification follows the same principle but replaces manual trial-and-error with algorithmic scoring. Instead of an astrologer spending hours checking divisional charts by hand, an AI evaluates every candidate time slot simultaneously and returns a probability-ranked shortlist within minutes.

Provide the basics — Enter your date of birth and the city where you were born. You do not need to know even an approximate time; the tool covers the entire 24-hour window automatically.

Answer tailored questions — The system generates a unique set of yes-or-no questions derived from the planetary configurations at each hourly slot. Your honest answers steer the algorithm toward the slots that match your lived experience and away from those that do not.

Review your ranked results — Once enough data points are collected, the tool displays a circular probability wheel highlighting the most likely birth hours. You can hover over any segment to see its confidence score and explore adjacent windows for comparison.

Divisional chart analysis — Navamsa, Dasamsa, and other divisional charts shift dramatically with small time changes. A birth time that is off by even thirty minutes can place planets in entirely different divisional houses, leading to misleading readings about marriage, career, or health.

Dasa timing predictions — Vimshottari dasa periods depend on the Moon's exact degree at birth, which in turn depends on precise time. An inaccurate birth hour can shift dasa start dates by months or years, making predictive astrology unreliable.

Muhurtha and relocation astrology — Selecting auspicious moments for weddings, business launches, or travel requires a solid natal chart as the baseline. Relocation charts that overlay your natal positions onto a new geography are equally sensitive — without the correct ascendant, the relocated houses tell the wrong story.
