Do Twins Have the Same Kundli? What a Few Minutes Change

Nearly the same, and never exactly. Twins (जुड़वां) share a date and a birthplace, and over a gap of minutes the planets barely move. Most of the two kundlis is therefore identical. The parts that differ are the ones tied to the turning sky rather than to the planets: the exact degree of the lagna, the divisional charts cut from it, and the Moon’s exact place in its nakshatra, which sets the dasha dates.

To show how much moves, this page computes four example births at Delhi on 21 March 2026, at 10:00, 10:06, 10:12 and 10:24 IST. They are illustrations of the arithmetic, not anyone’s chart, and the same method applies to any date.

Four Births, 24 Minutes Apart in All

All four have a Taurus lagna, so their twelve houses hold the same signs and every graha sits in the same house. Below that level they separate quickly. The ascendant moves about 6° over the 24 minutes. The D9 lagna is the same for the first three births and different for the fourth. The D10 lagna has already changed by 10:06, and it changes again before 10:24. The D60 lagna is different in every row.

The Moon moves only about 14 arcminutes over the same span, and stays in pada 2 of Ashwini, more than a degree short of the next pada. But its position inside the nakshatra is what fixes the dasha balance. The Moon is in Ashwini, so each birth opens in a Ketu mahadasha, and the later the birth, the more of that nakshatra the Moon has already covered and the less of the Ketu period remains. Six minutes bring its end forward by 12 days, and 24 minutes by 46 days. Every later mahadasha and antardasha moves by the same amount, because each one is counted on from the end of the first.

What Stays the Same

Across the four example births, all seven grahas computed here (the Sun, the Moon, Mercury, Venus, Mars, Jupiter and Saturn) keep their signs and their nakshatras. The Sun moves about 1.0 arcminute in 24 minutes, and the slower planets less. The panchang is shared too, unless a tithi or nakshatra happens to end inside the gap, because tithi, vara and the rest are read from the Sun and Moon, which have hardly moved. So twins have the same janma rashi and, unless the Moon was at the very edge of one, the same birth nakshatra and pada. That also means the same naming syllable on the nakshatra method, and the same Guna Milan inputs, since those come from the Moon. Rahu and Ketu are not computed on this page, but they move more slowly still.

What a Gap of Minutes Moves, in General

The example is one morning. For any birth at Delhi, the ranges below come from the extremes: the quickest and slowest rising signs there, and the slowest and fastest Moon of 2026. The dasha column runs from a Sun nakshatra with a slow Moon to a Venus nakshatra with a fast one.

Two things follow. First, twins born an hour apart will usually still share their Moon sign and nakshatra, because the Moon covers under a degree in that time, but their lagnas are 12° or more apart and may well sit in different signs, with every house shifted. Second, the dasha dates always differ, by days for a short gap and by weeks or months for a long one. How long each divisional lagna holds, chart by chart, is measured in how often the lagna, D9 and D10 change. The balance formula, and what one arcminute of the Moon is worth for each of the nine lords, is in dasha balance at birth.

Why the Recorded Times Matter More Than Usual

For one child, a birth time a few minutes out shifts one chart a little. For twins, the difference between the two charts is the whole question, and it is only as accurate as the two recorded times. If both were rounded to the same five minutes, the charts built from them will come out identical whatever the real gap was. A chart that has to be drawn with no time at all keeps only what the date fixes, as set out in kundli without birth time, and for twins that is exactly the part they share.

What This Page Does Not Say

It measures how two charts differ and stops there. It does not say whether the differences will show in two lives, which twin’s chart is “stronger”, or how an astrologer should weigh a shared rashi chart against a different D60. Those are questions of interpretation, and astrologers answer them in different ways. To compare two actual charts side by side, enter each birth time in the ascendant calculator, which also shows how far each lagna sits from the next sign, and in the dasha calculator.

In Brief

• Usually shared: the planets’ signs, nakshatras and houses, the Moon sign and birth nakshatra, the day’s panchang
• Differs within minutes: the lagna degree, the finer divisional lagnas (D60 first, then D10 and D9)
• Always differs: the dasha balance and every dasha date after it
• Can differ: the lagna sign itself, if the ascendant is near the end of a sign or the gap is long
