Parashara's Light 9.0 is widely regarded as one of the most powerful and flexible software suites for Vedic Astrology (Jyotish). Developed by GeoVision Software, this version represents a significant leap from its predecessors, offering advanced customization, high computational precision, and a user-friendly interface tailored for both professional astrologers and students. Core Capabilities and Calculations
The software is named after Maharishi Parashara, the sage credited with the Brihat Parashara Hora Shastra, the foundational text of Vedic astrology. Parashara's Light 9.0 aims to automate the complex mathematical models of this tradition with unmatched accuracy, often within one second of arc compared to official ephemeris data.
Customizable Worksheets: Users can design their own screens using a grid system to add and resize over 100 different tables and charts.
Dasha Systems: It supports numerous Dasha (planetary period) systems, critical for timing life events.
Divisional Charts (Vargas): The software can calculate all major divisional charts and provides specialized tools for analyzing Nakshatra spatial matrices. parashara-s light 9.0
Transits and Animation: An interactive transit screen allows users to "step through time" using a mouse wheel to see how planetary movements affect a natal chart. Key Features of Version 9.0
Version 9.0 introduced over 51 enhancements designed to streamline the astrological workflow.

One of the most debated topics in Jyotish is the calculation of ashtakavarga bindus and planetary aspects. Parashara’s Light 9.0 introduces a dynamic Orb Calculator that allows astrologers to set specific orbs for every planetary combination. More importantly, it introduces the "Parashara Precision Mode," which calculates aspects exactly according to the degree-based rules of Brihat Parashara Hora Shastra, eliminating the guesswork found in other software.

PL9.0 supports the full hierarchy of timing techniques:
The "Dasha Explorer" is a standout feature: it provides a timeline slider that lets you zoom into any day between 1900 and 2100 AD, showing exact planet positions and active dasha periods.
PL9.0 is not for everyone – and that is by design. It is a professional tool. Here is a breakdown:
You can run a batch transit or dasha analysis on an entire folder of charts. For example: “Find all charts in my ‘cancer’ folder where Mars transits the 8th house from Moon between 2025 and 2026.” The software returns a list instantly. Vimshottari (the most common) with sub-periods down to
PL9.0 uses the Swiss Ephemeris (v. 2.10) maintained by Astrodienst, which is based on NASA’s DE431 planetary ephemeris. This yields positions accurate to within 0.001 arcseconds for planets and 0.01 arcseconds for the Moon.
The default ayanamsa is Lahiri (Chitrapaksha), but advanced users can define their own ayanamsa if they follow a specific lineage.
Charts are now rendered with vector graphics, meaning they print and export flawlessly at any resolution. The new "Graphical Ephemeris" allows astrologers to visualise planetary motion over months or years in a single, intuitive display.
A leaked roadmap (unofficial) for Parashara’s Light suggests that version 9.5 (expected 2026) may include:
For now, version 9.0 is a mature, stable release that will remain relevant for at least 3–5 years.
