The Drekkana, or D3, is the third divisional chart (varga) in Vedic astrology. Where your main birth chart (the Rasi, or D1) gives the broad picture of your life, each divisional chart magnifies one area in finer detail. The Drekkana is traditionally read for matters of siblings and co-borns, and for your courage, valor, and inner drive. It is one of the sixteen classical divisional charts (Shodasavarga) described in the Brihat Parashara Hora Shastra.
The classical Parashara rule divides each 30-degree sign into three equal parts of 10 degrees each. These three parts are mapped to three signs counted from your natal sign:
So a planet's Drekkana sign depends on which 10-degree segment of its sign it occupies. Because the placements move into the 5th and 9th (the trinal signs sharing the same element), the D3 keeps a planet within a related, harmonious group of signs. This is the standard rule used across the Parashari tradition, and it is the rule our engine applies.
When you look at the D3, you are asking how the themes of siblings, support systems, and personal courage are organized in your chart. Astrologers traditionally examine the 3rd house and its lord within the Drekkana for the texture of sibling relationships and your capacity for self-effort, initiative, and resilience. The strength or affliction of relevant planets in the D3 is read alongside the same planets in the D1, never in isolation.
It is worth being honest about scope. A divisional chart refines and adds nuance. It does not predict a fixed event on a fixed date, a guaranteed outcome, or a number of siblings with certainty. The D3 is a lens for understanding tendencies and emphasis, and it is most meaningful when read together with the main chart, the dashas (planetary periods), and current transits.
Your Drekkana chart on Jyotish Live is calculated, not pulled from a generic template. We compute planetary positions with the Swiss Ephemeris, using the Lahiri (sidereal) ayanamsa and whole-sign houses, the same standards used throughout the site. From your exact birth date, time, and place, we find each planet's longitude in the D1, then apply the classical D3 division above to derive its Drekkana sign and house. The same math runs for everyone. What differs is your chart. If your birth time or place is off, the divisional placements can shift, so accurate birth data matters.
The Drekkana is one piece of a larger reading. For marriage and partnership you would look at the Navamsa (D9), for career at the Dasamsa (D10), and so on. Reading the D3 next to your D1 and your running dasha gives a grounded, layered view rather than a single snapshot. You can generate your Drekkana chart from your birth details and then ask follow-up questions about what the placements suggest.
The Drekkana is the third divisional chart in Vedic astrology. It is traditionally read for siblings and co-borns, and for your courage, valor, and inner drive. It refines what your main birth chart shows about these areas rather than replacing it.
Each 30-degree sign is split into three equal parts of 10 degrees. The first part (0 to 10 degrees) stays in the same sign, the second part (10 to 20 degrees) moves to the 5th sign from it, and the third part (20 to 30 degrees) moves to the 9th sign. This is the classical Parashara rule our engine uses.
No. The Drekkana points to tendencies and emphasis around siblings, support, and personal drive. It is not a guarantee of a specific number of siblings or a fixed event. It is best read together with the main chart, dashas, and transits.
