D20 Vimsamsa Chart Calculator

Vimsamsa, the D20 chart, is the chart of spiritual practice. It is looked at for the kind of worship that suits you, your relationship with a teacher or a deity, and the inner progress that comes from regular sadhana.

It is a quieter chart than D10 or D9. Few people consult it for the first time and many astrologers skip it, but those who work with devotional practice find it useful as a guide to temperament. It needs an accurate birth time, since the Ascendant moves every six minutes or so.

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 twenty parts of 1°30′. For a movable sign the count starts at Aries, for a fixed sign at Sagittarius and for a dual sign at Leo.

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 D20 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 spiritual practice. 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 spiritual practice.

• Do not use D20 to rank people by spiritual merit. It describes inclination, and sincerity is not on the chart.
• Many of the specific upasana rules attached to this chart come from later commentaries and differ between traditions.
• 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.
