Drekkana(D3) Chart Info - Free Astrology API

Overview

The Drekkana (D3) Chart Info API calculates planetary placements in the Drekkana divisional chart using a native's birth date, time, and geographical location. In Vedic astrology, the D3 chart divides each zodiac sign into three parts and is traditionally used alongside the main birth chart (D1) to explore themes related to siblings, courage, initiative, and personal efforts.

The API returns the Ascendant and planetary placements in the Drekkana chart, including each planet's zodiac sign number, house number, and retrograde status. The response covers the Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu, Ketu, and outer planets. This information helps developers display D3 chart placements and support traditional Vedic astrology analysis.

To calculate Drekkana chart information, provide the birth year, month, date, time, latitude, longitude, and timezone. You can also configure the observation point as geocentric or topocentric and select a supported Ayanamsha setting, such as Lahiri or Sayana. The API returns the results in JSON format, making it easy to integrate D3 chart data into web applications, mobile apps, and Vedic astrology software.
