In Vedic astrology, your birth chart (the Rasi or D1) is only the first layer. Each sign spans 30 degrees, and the classical texts divide those degrees into smaller parts to create divisional charts, also called vargas. Each varga magnifies one area of life. Where D1 shows the whole picture, the Navamsa (D9) focuses on marriage and inner dharma, the Dasamsa (D10) on career, and so on. A planet can look strong in D1 yet sit in a difficult divisional sign, which is exactly the nuance these charts are designed to surface.
Two methods are in play, and we are precise about which one applies where.
The sixteen Shodasavarga charts are D1, D2, D3, D4, D7, D9, D10, D12, D16, D20, D24, D27, D30, D40, D45 and D60. For these, we apply the classical sign-mapping rule rather than the raw harmonic value, because that is what the tradition specifies.
These are areas of emphasis, not verdicts. A divisional placement adds context to the natal chart. It does not, on its own, fix any outcome.
Every divisional chart on Jyotish Live is generated from your exact birth time and place using the Swiss Ephemeris with the Lahiri (sidereal) ayanamsa and whole-sign houses, the standard for Jyotish. The sixteen Shodasavarga charts use the classical Parashara sign rules described above, with the harmonic formula as the fallback for other divisions. Each chart is calculated from your data, not filled in from a one-size-fits-all template. Astrology is offered here as a tool for reflection and self-understanding, not as a guaranteed prediction or a substitute for your own judgment.
A divisional chart, or varga, divides each 30-degree sign into smaller parts to focus on one area of life. The D9 Navamsa zooms into marriage and inner dharma, the D10 Dasamsa into career, and so on, adding detail that the main D1 chart cannot show alone.
The sign is split into nine equal parts of 3 degrees 20 minutes. The counting begins from the same sign for a movable sign, from the 9th sign for a fixed sign, and from the 5th sign for a dual sign, following the classical Parashara rule from the Brihat Parashara Hora Shastra.
Parashara describes sixteen primary divisional charts, called the Shodasavarga: D1, D2, D3, D4, D7, D9, D10, D12, D16, D20, D24, D27, D30, D40, D45 and D60. Some traditions reference charts up to D60 and beyond for finer analysis.
After the D1 Rasi chart, the D9 Navamsa is considered the most important. It refines the strength of every planet and is read closely for marriage, dharma and how the promise of the birth chart actually matures.
They are computed. Each chart is calculated from your exact birth details using the Swiss Ephemeris with the Lahiri sidereal ayanamsa and classical Parashara rules, never filled in from a generic template.
