D12 Dwadasamsa Chart Calculator

Dwadasamsa, the D12 chart, is read for parents. The mother is seen through the fourth house and the Moon, the father through the ninth house and the Sun. D12 adds a second layer, covering the health, character and circumstances of your parents, and the nature of the bond with them.

It is also where some astrologers look at inherited traits and the family line. The twelve parts per sign make it a fine-grained chart, so the Ascendant changes about every ten minutes. Treat a vague birth time with caution.

Read it with the D1 birth chart beside it. If you also want the marriage and strength chart, open the D9 Navamsa.

Each sign is divided into twelve parts of 2°30′. The count starts from the sign itself and runs forward through the zodiac, one sign per part.

Your birth details go to the same astrology service that powers the free Kundli. The page reads the divisional Ascendant, each planet’s sign, house, degree and part from the response and draws them with the Kundli chart renderer.

This illustration contains invented positions to show the chart layout.

• The top diamond is the first house. The 3 in it means Gemini is the divisional Ascendant.
• Houses follow anticlockwise from there, each with the next sign number.
• Each label is a short planet name and its degree inside that sign. A star marks a retrograde planet.
• In your own D12 chart the signs and houses come from the divisional positions, so they will rarely match your D1.

The houses keep their usual meanings. What changes is which planets fall in them, and that is what makes the chart specific to parents. Use the table to find the house you want, then read the planets in it.

Once the chart is drawn, work through it in this order. Each point below is a place astrologers look first for parents.

• Do not read D12 to predict illness or death of a parent. That is beyond what the chart can responsibly say, and it can cause needless worry.
• Treat D12 as a view on the relationship. The family circumstances you know firsthand matter more than any placement.
• Use a birth time from a certificate or hospital record, check AM and PM, and choose your town from the suggestions so the coordinates are right.
• If another website shows a different chart, compare the ayanamsa and the division rule it uses. This calculator uses the sidereal zodiac with the Lahiri ayanamsa.

The smaller the part, the faster the divisional Ascendant moves. The column on the right shows roughly how long it takes the Ascendant of each chart to change sign. The figures are averages, because the real speed varies with your latitude and the sign that is rising.

If you are not sure of your birth time, start with D1 and D9, which are the most forgiving, and ask an astrologer about rectification before you rely on D40, D45 or D60.

D12 चार्ट को द्वादशांश कहते हैं और इसे माता-पिता के लिए देखा जाता है। सूर्य और नवम भाव पिता के लिए तथा चंद्र और चतुर्थ भाव माता के लिए देखे जाते हैं। हर राशि के बारह भाग होते हैं और गिनती उसी राशि से शुरू होती है। माता-पिता के स्वास्थ्य या आयु पर भविष्यवाणी के लिए इसका उपयोग न करें।

चार्ट बनाने के लिए जन्म की तारीख, सही समय और जन्म स्थान भरें। ज्योतिष एक पारंपरिक विद्या है, इसे चिकित्सा, कानूनी या वित्तीय निर्णयों का आधार न बनाएं।
