Question 1

What is Birth Time Rectification (BTR)?

Accepted Answer

Birth Time Rectification (BTR) is the process of determining your accurate birth time when the recorded time is uncertain. Vedic astrology uses specific life events (marriage, career changes, childbirth, etc.) matched against planetary Dasha periods to reverse-calculate the most likely birth time within the stated uncertainty window.

Question 2

Why is accurate birth time important?

Accepted Answer

Accurate birth time is critical for correct Lagna (Ascendant) calculation, which changes approximately every 2 hours. Lagna determines the entire house system, planet strengths through house placement, and the timing of Dasha periods. An error of just 4-5 minutes can shift the Ascendant by more than 1 degree.

Question 3

How many life events are needed for BTR?

Accepted Answer

For reliable rectification, at least 3-5 accurately dated major life events are recommended. The engine scores each candidate birth time against classical Dasha significations of the events. More events produce more precise results. Events like marriage, childbirth, career changes, property purchase, and major illnesses work best.

Question 4

Is BTR guaranteed to find the exact birth time?

Accepted Answer

BTR narrows down the most probable birth time window based on available life events, but it cannot guarantee the exact minute. The more events you provide and the more accurate they are, the narrower the uncertainty window becomes. Classical BTR methods combined with our engine can typically reduce uncertainty from hours to minutes.

Question 5

What is the difference between BTR and birth chart calculation?

Accepted Answer

Birth chart calculation simply places planets based on the given birth time. BTR is a diagnostic process that uses real life events to verify and correct an uncertain birth time. Think of BTR as quality assurance for your birth chart -- without accurate time, even the best chart calculation is built on an incorrect foundation.
