Divisional Charts Calculator

D1 (Rashi) is the primary chart showing actual planetary positions. D2 (Hora) divides each sign into two parts and indicates wealth and financial tendencies. D3 (Drekkana) divides each sign into three parts, revealing information about siblings, courage, and communication. D4 (Chaturthamsa) divides into four parts for property, real estate, and fixed assets. D7 (Saptamsa) divides into seven parts and reveals information about children and progeny.

D9 (Navamsa) is the second most important chart after D1, used for marriage, spouse characteristics, spiritual evolution, and confirming planetary strength. D10 (Dashamsa) reveals career details, professional reputation, and the nature of one's public contribution. D12 (Dwadashamsa) relates to parents and ancestral inheritance. D16 (Shodashamsa) governs vehicles, comforts, and happiness from material possessions. D20 (Vimshamsa) covers spiritual practices and religious inclinations.

Each divisional chart is calculated by dividing each zodiac sign into a specific number of equal parts and assigning each part to a zodiac sign according to classical rules. For D9 (Navamsa), each 30-degree sign is divided into nine parts of 3 degrees 20 minutes each. The starting sign for each element group differs: fire signs start from Aries, earth from Capricorn, air from Libra, and water from Cancer.

For D10 (Dashamsa), each sign is divided into ten parts of 3 degrees each. Odd signs start from the same sign, and even signs start from the 9th sign from themselves. These rules vary for each divisional chart and follow the formulas prescribed in Brihat Parashara Hora Shastra. Kaala applies these classical rules with Swiss Ephemeris-grade precision in the underlying planetary positions, ensuring accurate divisional chart generation.

When a planet occupies the same sign in both the Rashi chart and a divisional chart, it gains special strength for that divisional chart's domain. A planet in the same sign in D1 and D9 is called Vargottama in Navamsa, gaining strength for marriage and soul-level expression. A planet in the same sign in D1 and D10 gains career strength.

The concept extends to Varga Visesha — planets appearing in their own sign or exaltation across multiple divisional charts accumulate strength that is measured through the Shodasavarga scheme. Parashara assigns specific point values: own sign in a Varga earns points, exaltation earns more. Planets scoring high across all sixteen Vargas (called Paramatamsa status) are extraordinarily powerful and produce exceptional results during their Dasha periods. Kaala computes this Varga strength score as part of the divisional charts analysis.

The most commonly used divisional charts for practical predictions are D9 (marriage analysis), D10 (career analysis), and D7 (children and progeny). Before making a marriage prediction, a thorough Jyotishi examines the D9 chart's 7th house, Venus placement, and the D9 Lagna lord's condition. Before predicting career trajectory, the D10 chart's 10th house, Sun placement, and the strongest planets in D10 are assessed.

For questions about property and vehicles, D4 is examined. For spiritual development questions, D20 is consulted. For educational achievements, D24 is relevant. Kaala's AI interpreter Jyothi accesses divisional chart data when generating specialized predictions, ensuring that the interpretation goes beyond Rashi-level analysis for domains where divisional charts provide critical additional insight.
