Drekkana Chart Calculator (D3)

The **Drekkana (D3)** divides each zodiac sign into three equal parts of 10° each, and is one of the oldest divisional charts in Vedic astrology, classically tied to siblings, courage, and personal initiative — the "3rd house themes" of a chart examined in finer detail.

What Is the Drekkana (D3) Chart?

Each 30° sign splits into three equal 10° parts. The first part keeps the sign itself, the second counts five signs ahead, and the third counts nine signs ahead — one of the more mathematically direct divisional rules, and one used since the earliest classical texts.

Reading Siblings and Courage From the D3

The 3rd house of the D3 chart and its lord are examined for questions about siblings — their number, relationship quality, and general nature — as well as personal courage, initiative, and short journeys, the traditional domain of the 3rd house carried into this finer division.

Why Mars Matters in the Drekkana

Because the 3rd house is naturally associated with Mars-like qualities (courage, effort, initiative), Mars’s placement and dignity in the D3 chart is given particular attention when assessing a person’s natural drive and willingness to take initiative.
