This page walks you through installation, the twelve modules of Sithars Astrology, and where to find help — laid out the way a horoscope itself is: house by house.
Four quick steps and the software is ready — the same setup works on lower-end and higher-end PCs, tablets, and Android devices.
Run the installer you received after purchase. The software is lightweight and responsive, so it runs comfortably on modest hardware as well as newer machines.
Set your name, location defaults, language preference, and print/report formatting before generating your first chart. These settings apply automatically to every module afterward.
Every purchase includes lifetime updates. Use the update option on first launch and periodically afterward to make sure you have the latest calculations and fixes.
Your saved horoscopes live in a local database. If you move to a new PC or reinstall, use Restore Database to bring back every chart you've generated — nothing is lost.
These are the modules you'll use most — the core birth chart and the deeper Naadi-based readings built on top of it.
Enter birth date, time, and place to generate a compact, single-page horoscope — ideal for a quick reading or when you need something short to hand to a client.
The expanded version of the same chart — dasa/bhukti periods, planetary positions, and house-by-house detail across multiple pages, suitable for print or PDF.
Generates a reading centered on the Moon's position at birth, following traditional Naadi method — useful for a second, moon-anchored perspective alongside the main chart.
Applies the Pirugu Naadi method to the birth details already on file, producing a supplementary reading in the same traditional Naadi lineage.
Tools for the decisions people usually come to an astrologer for — marriage, naming a child, and understanding a birthday.
Load both horoscopes and the module scores compatibility across the traditional matching points, giving you a clear match/no-match breakdown for marriage discussions.
Builds a reading from the arudam (rising-point) positions of the chart — a complementary technique to the main horoscope for a sharper day-to-day picture.
Enter the baby's birth star and the module suggests names in the matching syllable group — handy when a family wants a name aligned to the birth nakshatra.
Two lighter, focused modules: Birthday Secrets reads the year ahead from the birthday chart, and Love Secrets looks specifically at relationship indicators between two charts.
A standalone calculator — enter a name or date and get the corresponding numerology values, useful as a quick cross-check alongside a horoscope reading.
The traditional query-based (prasannam) and remedy modules, plus specialised readings for health and gemstones.
Reads the chart for karmic afflictions and suggests the corresponding traditional remedies (pariharam) tied to those indicators.
Produces a longer, print-ready report format. If a printout looks like it's only showing one page when it should show several, open Application Settings and confirm "include footer" is switched on before reprinting.
Two traditional prasannam (question-and-answer) systems used when someone has a specific question rather than a full-life reading. Enter the query details and the module returns its indication.
Folk-tradition divination systems, included alongside the main astrology modules for practitioners who work with these methods.
A prasannam variant framed around deity indicators, used the same way as the other query-based modules.
Surfaces health-related planetary indicators from the horoscope. This is a traditional astrological reading, not a medical diagnosis — always pair it with professional medical advice.
Suggests gemstones associated with the strengthening or balancing of specific planets in the chart.
Krishnamurti Paddhati (KP) is a separate, more technical prediction system built into the software for users who already work with sub-lord based analysis.
Generates the KP-format chart, including sub-lord divisions, for users following the Krishnamurti system rather than (or alongside) the classical Rasi chart.
If you're new to KP, generate a One Page Astrology chart first for the same birth details — comparing the two side by side is a good way to learn how the sub-lord divisions relate to the classical houses.
