Birth Time Rectification
Narrow doubtful birth time with dated events vs dasha and transits. AI proposes window and lagna—you accept to refresh all charts.
Find your birth time
We will ask about dated life events (marriage, children, career moves, relocations, health, losses) and narrow the clock time that fits your chart.
Have rough dates ready for about 3–5 major events before you start.
- Per Lagna sign~2hThe rising sign changes roughly every two hours.
- Per degree~4 minThe ascendant moves about one degree every four minutes.
- Per Navamsa~13 minThe D9 ascendant shifts about every 13 minutes.
When the clock time on your birth certificate is missing or doubtful, rectification narrows the plausible window by comparing major life events against dasha and transit triggers. Our guided session asks for your birth date and place, a rough time-of-day hint, and dated milestones you are willing to share. The AI works through structured chart tools—not casual guessing—and ends with a proposed time, confidence and ascendant for you to accept or refine. Better birth time unlocks reliable houses, lagna and divisional charts for every other tool on this site.

FAQ
Rectification questions
What is birth time rectification?
It is the practice of inferring a more accurate birth time from event history and chart timing techniques when the recorded time is unknown or rounded.
How long does it take?
Plan about ten minutes to enter events and respond to follow-ups. More precise memories improve the result.
What events should I prepare?
Marriage, moves, job changes, accidents or awards—with month and year at minimum. Exact dates help when you have them.
Will it change my Moon sign?
Usually not, unless your birth date was near a Moon sign change. It mainly shifts lagna and house cusps.
Can I use the result on other pages?
Yes—accept the proposed time to update your profile and refresh natal, dasha and matching charts.
