Impact Of Birthtime Error


There are twins in this world who are born 1-2 minutes apart, but live significantly different lives. There may be some similarities between closely born twins, but there can be significant differences too.So this proves that divisional charts and special lagnas, which change very fast, have a great bearing on a native’s fortune. If one’s birthtime is wrong by 2 minutes, lagna and special lagnas in some divisional charts change and so the results change. This is how we can explain the differences between twins.

Now the question is — if changes in lagna and special lagnas in divisional charts explain the different fortunes of twins, what about people who don’t have a twin? Well, the same thing applies to them. If we analyze the chart cast with a birthtime that is wrong by 2 minutes, we are no longer examining the chart of the native – we are simply looking at the chart of his hypothetical twin! The results predicted need not be true.

Lagna in D-1 changes rasi once in 2 hours. Some people make predictions only using D-1, but that is unscientific and against the teachings of maharshis. Due to divine powers and God-given intuition, one can be successful in one’s predictions only using D-1, but that is clearly unscientific. We should see different areas of life in different divisional charts, as taught by Maharshi Parasara. When we do that, we need an accurate birthtime. If one’s birthtime is between 9:02 am and 9:08 am, can we make accurate predictions using an average of 9:05 am? No! Many people are born within the small span of 6 minutes (between 9:02 and 9:08) and they can be significantly different from each other (e.g. twins). Applying precise techniques is pointless when we only have an approximate time. So let us conclude that we must first make sure that we are working with an accurate birthtime. Readers should remember that our analysis could be only as accurate as our data!

We are often told by clients that their birthtime is very accurate. However, it is this author’s experience that birthtimes reported by people are seldom accurate. There can be various reasons behind a birthtime error: (1) using an unadjusted clock/wristwatch showing a slightly incorrect time, (2) forgetting to note the birthtime exactly after birth and noting down it a little later with some manual correction applied to compensate for the lapse, (3) wrong memory of mother or father when giving the correctly noted birthtime to an astrologer, (4) using the wrong definition of ‘birth’.

Birthtime rectification is the process of correcting the reported birthtime before proceeding to make predictions based on the birthtime. There are some formulas in literature for birthtime rectification, but these assume that human births happen in certain quanta. For example, an approach may assume that nobody is born during a period of 3 minutes and people can be born in a period of half a minute then. Then again, nobody is born for 3 minutes and people can be born in a period of half a minute following it. Like this, time is divided into certain quanta in which people can be born. Then we find the nearest “human birth can happen now” quantum from the reported birthtime and use it as the rectified (corrected) birthtime.

Out of these methods, some of the reasonable methods are the ones based on (a) Tattva siddhaanta, (b) Pranapada lagna in navamsa, and, (c) Kunda. The first method beyond the scope of this book and the other two fail the acid test of twins. If we were to apply those methods to the charts of twins born 2 minutes apart, the rectified birthtimes of the two twins would be either the same or too far apart.

In essence, most of the birthtime rectification techniques described in literature do not work. The only correct way to rectify a birthtime is to find a time in the neighborhood of the reported birthtime so that we can explain the nature, credentials, attitude and aptitude of the native and the known events from the native’s past. This is a laborious process, but there is no other way.

Suppose we are told that one was born between 9:02 and 9:08 am and suppose we are looking at his chart. Because we don’t know the exact birthtime, we can look at a range. If we do that, we are potentially looking at thousands of people born during that time. Our native could be anyone among thousands of people born in that range. But all those thousands of people have significant differences. We want to identify our native among those thousands of people and the only way is to look at the known past. That’s the only thing that distinguishes him from others born closely.

So we should look at 9:02, 9:03, 9:04 etc and see which one explains the known past better. The rectified birthtime is the birthtime with which the known life events of the native make sense.


If you want to know when lagna in a particular divisional chart changes, click the right mouse button on it. In the pop-up context menu, select “when will lagna change”. You will be told how much time should be added/subtracted to the birthtime to change lagna in that divisional chart to the next/previous sign.
