Divisional Chart (Varga) Calculator
A Vedic reading rarely stops at the birth chart. Each varga re-slices the same sky at a finer resolution and is read for one department of life — D10 for career, D12 for parents, D24 for education. This puts eight of them side by side so you can see where a planet holds up and where it quietly falls apart.
What this calculator works out
- Eight vargas at once
- D7, D9, D10, D12, D16, D24, D30 and D60 for all nine grahas, in one table.
- Each varga's signification
- What the tradition reads each divisional chart for, so the columns mean something rather than being decoration.
- Vargottama flags
- Planets holding the same sign in D1 and D9.
How it works
Every varga divides each 30° sign into a fixed number of parts and maps each part onto a sign by its own classical rule. D12 counts from the sign itself; D16 starts from Mesha, Simha or Dhanu depending on modality; D24 starts from Simha for odd signs and Karka for even ones; D30 is the one varga with unequal divisions, five uneven slices ruled by the five non-luminary planets. Divisions get narrower as the number rises, so the higher vargas demand a far more accurate birth time than D1 does.
Step by step
- Every planet's sidereal longitude is computed once from your birth details.
- For each varga, the sign is divided into that varga's number of parts.
- Each part maps to a sign by that varga's own classical rule — which differs from varga to varga.
- D12 counts from the sign itself; D16 starts from Mesha, Simha or Dhanu by modality; D24 starts from Simha for odd signs and Karka for even ones.
- D30 is the exception: five unequal slices ruled by the five non-luminary planets, reversed for even signs.
A worked example
Input: A planet at 15° Aries, in D30
- Aries is an odd sign, so the odd-sign slice order applies
- Odd order: Mars 0-5° · Saturn 5-10° · Jupiter 10-18° · Mercury 18-25° · Venus 25-30°
- 15° falls in the 10-18° slice → Jupiter
- Jupiter's odd-sign trimshamsha is Sagittarius
Result: Sagittarius. Note this is not an equal division — the Jupiter slice is 8° wide while the Mars slice is 5°.
How to read your result
- Use the varga that matches the question
- D10 for a career question, D12 for one about parents, D24 for education. Reaching for all eight on every question produces noise, not depth.
- Agreement across charts is the signal
- A planet that holds up in D1, D9 and the varga relevant to the question is read as genuinely strong. One that looks good in D1 alone is read as promising more than it delivers.
- The higher vargas are fragile
- A D60 slice is half a degree wide. Roughly a minute of clock error moves the Moon a whole shashtiamsa, so treat that column as indicative unless your birth time is recorded rather than remembered.
What changes the answer
- D30 never yields Cancer or Leo, because the Sun and Moon own no trimshamsha. If a calculator gives you one, its table is wrong.
- D60 convention genuinely varies — some sources count even signs in reverse. This counts forward for all signs, which is what most software does.
- A varga is not a separate horoscope. Read on its own it means nothing; it only works against the birth chart.
- D2, D3, D4 and D20 from the Shodashavarga scheme are not implemented here, and the table shows only what it actually computes.
Frequently asked questions
What is a divisional (varga) chart?
A chart built by dividing each sign into equal parts and re-mapping each part onto a sign. It is not a separate horoscope — it is a magnifying glass on the birth chart, and it only means anything read alongside it.
Which varga is read for what?
D7 for children, D9 for marriage and underlying strength, D10 for career, D12 for parents and lineage, D16 for vehicles and comforts, D24 for education, D30 for weaknesses and resilience, and D60 for past-life karma. Most practical readings use D9 and D10 heavily and reach for the others only on a specific question.
Why does D30 behave differently from the others?
It is the one standard varga with unequal divisions. Each sign splits into five uneven slices ruled by Mars, Saturn, Jupiter, Mercury and Venus, in reverse order for even signs. The Sun and Moon own no trimshamsha at all, which is why Cancer and Leo never appear in a D30 result.
How accurate does my birth time need to be?
It depends on the varga. A D9 division is 3°20' wide; a D60 division is 0°30'. Roughly a minute of clock error is enough to move the Moon a whole shashtiamsa, so treat the D60 column as indicative unless your birth time is recorded rather than remembered.
What is vargottama?
A planet holding the same sign in the birth chart and the navamsa. It is read as unusually stable and strong — the two charts agreeing rather than pulling against each other.
Why do some sites give me a different D60?
Because D60 is the one varga where sources genuinely disagree. Some count even signs in reverse from the sign. This tool counts forward from the sign for every sign, which is what most software implements. That is a convention gap, not an error on either side.
Are D2, D3, D4 and D20 missing?
Yes — only the eight vargas above are implemented, and the tool lists exactly what it computes rather than showing empty columns. The Shodashavarga scheme includes others that are not here yet.
