A D60 chart calculator is a tool used in Vedic astrology to calculate the D60 or Shashtiamsha chart. This chart provides detailed insights into various aspects of life based on the exact degree of the planets in the natal chart. The D60 chart is one of the divisional charts in Vedic astrology, and it divides each zodiac sign into 60 equal parts to offer a deeper understanding of an individual’s destiny and characteristics.
Purpose and Functionality
The D60 chart calculator’s main purpose is to determine the precise position of planets in the D60 chart. This chart is crucial for making detailed astrological predictions and understanding the subtle influences on a person’s life. The D60 chart is especially important for analyzing the hidden and karmic aspects of life, which are not always evident in the main birth chart.
Inputs Needed for the D60 Chart Calculator
- Birth Time and Date: The exact time and date of birth are essential for determining the accurate planetary positions at the time of birth.
- Longitude and Latitude of Birthplace: These geographic coordinates help calculate the local sidereal time, Ascendant, and house positions.
- Sidereal Zodiac: Vedic astrology uses the sidereal zodiac, which considers the actual positions of the constellations in the sky, adjusted for the precession of the equinoxes.
Key Formula
The key formula used in the D60 chart calculation involves determining the Shashtiamsha, or the 60th division of a sign. Each zodiac sign of 30 degrees is divided into 60 parts, with each part being 0.5 degrees.
Calculation Steps
1. Calculate the Longitude of Planets
Find the exact longitudinal degree of each planet in the natal chart using the birth details and astronomical data.
2. Determine the Sign Position
Identify which sign each planet is positioned in.
3. Calculate the Shashtiamsha Position
- Each sign is divided into 60 equal parts, so each part is 0.5 degrees.
- For any given planet, divide its degree position within its sign by 0.5 to find out which Shashtiamsha it belongs to.
- Each Shashtiamsha is associated with a specific sign, which cycles through the zodiac in a particular sequence. The sequence and the corresponding lordships can vary based on different astrological texts or traditions.
4. Construct the D60 Chart
Place each planet in the appropriate sign of the Shashtiamsha, based on its calculated position.
Example
Let’s take an example to understand the calculation better.
Suppose a planet is at 6 degrees in Aries:
- Aries extends from 0 degrees to 30 degrees.
- At 6 degrees, the planet is in the 13th Shashtiamsha (since 6 divided by 0.5 equals 12, and adding 1 for the correct count).
- Based on the sequence used for the Shashtiamsha, determine which sign this 13th division corresponds to and place the planet there.
This is a simplified explanation, and actual calculations might require more precise astronomical and astrological software or tables, especially to account for the specific Shashtiamsha sequence and rulerships, which can vary in different Vedic astrology traditions.

Conclusion
A D60 chart calculator is a valuable tool in Vedic astrology, providing deeper insights into the hidden and karmic aspects of life. By understanding the precise positions of planets in the Shashtiamsha chart, astrologers can make more detailed and accurate predictions. The D60 chart helps reveal subtle influences that might not be evident in the main birth chart, making it an essential component of comprehensive astrological analysis. Whether you’re an astrologer or someone interested in understanding your astrological profile better, a D60 chart calculator can offer valuable insights into your life’s journey.
