What the D12 chart is read for
The D12 is read for parents and for lineage: the condition of the mother and father, the household a person began in, and the inheritance - temperamental as much as material - that arrived before any choosing. It is the second look at the 4th and 9th houses, and it is often more articulate than the D1 about which parent a given difficulty actually belongs to.
How the D12 is calculated
Each sign divides into twelve parts of 2°30', counted from the sign itself. The twelve-fold division maps a sign onto the whole zodiac, so every dwadasamsa has a natural house correspondence.
| Property | Value |
|---|---|
| Division | D12 |
| Span of one amsa | 2°30' |
| Amsas across the zodiac | 144 |
Reading it alongside the birth chart
Read the 4th and 9th houses of the D1 first, then the D12 for which parent and which side of the family the matter sits on. For a question about a parent's own life rather than the native's experience of them, that parent's own chart is the better instrument.
What a divisional chart will not tell you
A difficult D12 describes a difficult inheritance, not blame. It also cannot report on a living parent's health - that is their chart's business, and medical questions belong with clinicians.
Frequently asked
- What is the Dwadasamsa chart read for?
- Parents and ancestry - the mother and father, the household of origin, and what was inherited before choice. It is the second opinion on the 4th and 9th houses.
- Can the D12 tell me about my parents' health?
- It describes your experience of your parents and the family inheritance. A parent's own health sits in their own chart, and medical questions belong with a doctor rather than with any chart.
