Birth-time rectification

Is your birth time correct?

Your date of birth is usually certain, but the birth time often rests on memory. Enter your birth details, then move the time by 5, 10 or 30 minutes and see whether your lagna and current mahadasha change.

Enter your birth details above to see your chart.

How to read the comparison

  • Your stated time and the adjusted time are shown together. Anything that moved is marked “changed”.
  • If the lagna changes, you were born near a lagna boundary, and pinning down the time matters more.
  • If the mahadasha changes, your whole dasha table shifts. Check the birth certificate or hospital record.

Why birth time matters

In Vedic astrology the lagna (ascendant sign) changes every ~2 hours, so a 10-minute difference is often enough to shift the lagna, especially if you were born near a sign boundary (sandhi).

The Moon's nakshatra shifts every 6-7 hours as well. If you were born near a nakshatra boundary, your Vimshottari mahadasha's starting lord will change, shifting the entire dasha sequence by years.

This page does not rectify your birth time. That takes an astrologer matching your chart against life events. It shows you how sensitive your chart is, so you can decide whether to push your parents on the exact minute, or ask a pandit for a formal rectification.

FAQ

Questions about birth time

I don't know my exact birth time. What should I do?

Start with hospital records, birth certificate, or ask your parents: often you can narrow it to within 5-10 minutes. If you truly have no starting point, an experienced astrologer can do a formal chart rectification, matching your chart against known life events.

Does even a 5-minute difference really matter?

Usually not, five minutes rarely changes the lagna. But if you were born near a lagna or nakshatra boundary (sandhi), five minutes can be enough. The tool on this page will show you.

Does Nakshara do rectification?

This tool shows sensitivity, not rectification itself. Formal rectification needs matching life-event dates against the chart. That's an astrologer's job, not a computed one.
