A python package for Vedic Astrology, with a particular focus on the Krishnamurthi Paddhati system

VedicAstro is a python library built for the study, practise, research and application of traditional Vedic Astrology. The goal of this package is to generate chart and planetary position data for Vedic Astrology systems , particularly Krishnamurthi Paddhati (KP) system. This package, primarily uses the sidereal branch of the flatlib library to obtain data from the swiss ephemeris (pyswisseph)

Installation

Create a virtual environment in this project directory and install the required packages:

From PyPi

pip install vedicastro

NOTE: PyPI no longer supports specifying external packages (eg:git repo URLs) in install_requires in the setup.py file. (Read this) Packages specified in dependency_links will also not get automatically installed(Read this). To install the required package flatlib from the sidereal branch, run the following command, after completion of above pip install VedicAstro command:

pip install git+https://github.com/diliprk/flatlib.git@sidereal#egg=flatlib

From local clone of Git Repo

Clone the repo:

https://github.com/diliprk/VedicAstro.git

Create a python virtual environment using venv

python -m venv astrovenv
source astrovenv/bin/activate
pip install --upgrade  pip
pip install -r requirements.txt

In Windows: source astrovenv/bin/activate does not work, so you have to do cd astrovenv\Scripts && activate in command prompt,

Alternatively, you can also use miniconda as your virtual environment manager:

conda create -n astrovenv python=3.11
conda activate astrovenv
pip install -r requirements.txt

Study and Reference

The main class in this package is the VedicHoroscopeData class, which has the following methods:

1. generate_chart - Generates a flatlib.Chart object for the given time and location data
2. get_planets_data_from_chart - Generate the planets data table from a flatlib.Chart object
3. get_houses_data_from_chart - Generates the houses data table from a flatlib.Chart object
4. get_planet_wise_significators - Generate the ABCD significators table for each planet
5. get_house_wise_significators - Generate the ABCD significators table for each house
6. compute_vimshottari_dasa - Computes the Vimshottari Dasa for the chart
7. get_planetary_aspects - Computes aspects (like Trine, Sextile , Square , Conjunction etc.) between planets. This method is more popular in Western Astrology systems

You can run the below notebook, to get a handle of the above basic operations.

Horary (Prasna)

A seperate functionality has been added for computing KP Horary (Prasna) Chart, as it requires a completely different set of datetime objects for the ascendant computation. You can invoke these functions get_horary_ascendant_degree and find_exact_ascendant_time in the horary_chart.py for preparing chart and tables for a KP Horary Question.
You can run the below notebook, to get a handle of the basic operations for constructing a horary chart.
