Enter one proposed birth time and verify it with KP New ayanamsha, Placidus cusps and Mean Rahu. The tool applies Astro Nilmani's four core rectification rules and then verifies the proposed time against dated life events using Law of Judgment, Vimshottari DBA and Nadi house-combination rules.
| Rule | Condition | Observed | Status |

Birth time rectification is used when a recorded time is approximate or when fine KP cusp and Sub-Lord judgments do not agree with known life events. In KP astrology, a difference of a few minutes can change the Ascendant cusp, Star Lord, Sub Lord or Sub-Sub Lord even when the broader birth chart appears similar.
The calculator checks one proposed birth time at a time. It calculates all four Astro Nilmani rectification rules together: the Moon Sub/Sub-Sub target houses, Lagna-9th interrelation, the ninth cusp connection with Jupiter/Venus/Sun, and the Lagna-Moon lord relationship. Each rule is shown separately as PASS or FAIL. After Part 1, dated life events can be checked against the active Mahadasha, Antardasha and Pratyantardasha using Astro Nilmani's event-house combinations and Law of Judgment.
Birth time rectification is an astrologer-led judgment. Instead of automatically ranking many nearby times, this tool lets the astrologer enter a specific proposed time, inspect all four structural rules, then manually try another minute if necessary.
জন্ম সময় কয়েক মিনিট এদিক-ওদিক হলে KP Astrology-তে Lagna cusp, Star Lord, Sub Lord এবং Sub-Sub Lord বদলে যেতে পারে। এই tool-এ একটি নির্দিষ্ট birth time manually দিয়ে চারটি rectification rule একসঙ্গে দেখা যায়। প্রয়োজন হলে time কয়েক মিনিট বদলে আবার check করা যায়।
No. This is a manual verification support tool. Enter one proposed time, review the four rules, then change the time manually if you want to test another candidate.
Yes. Change the birth-time field manually - for example from 03:30 to 03:33 or 03:35 - and run the four-rule check again.
Fine birth-time rectification depends on smaller KP subdivisions. This tool therefore calculates Sub-Sub Lords internally even though the normal public horoscope report may not display them.
All four rules are still shown. In Astro Nilmani's judgment, a 3/4 or 4/4 Moon-house match is a strong primary indication. When Rule 1 gives only 2/4, the remaining three rules become especially important for review.
Use events with dates you can verify, such as a recorded marriage or job joining date. Keep approximate dates marked as approximate, and compare candidate times against more than one event.
This tool applies Astro Nilmani KP rules to support investigation. A higher score does not independently prove a birth time, and the result should be reviewed with the records and chart context.
