Panchapatchi Sastra
Ancient Tamil wisdom, in the browser.
Our first build for Rishabanandhar Swamigal's following — a web application that takes the ancient Panchapatchi ("Five Birds") system of Tamil astrology and turns it into a polished, personalised, multilingual experience anyone can open on their phone, tablet, or browser.

தமிழ் · Tamil5 birds × 10 jamams — a real day's prediction grid from the live app.
EnglishThe same prediction grid, fully localized for English readers.
മലയാളം · MalayalamThe same prediction grid, localized for Malayalam readers.
The Challenge
An intricate system, made effortless
Each day splits into 10 time periods (Jamams), and a person's fortune within them depends on their birth star (Nakshatra) — one of 27, mapped to one of five birds. Layered on top is a complete Tamil Panchangam and astronomical timings that shift with sunrise at every location. The goal: make all of it effortless and accurate across languages and countries — while letting the content owners manage everything without touching code.
- 27 birth stars → 5 birds — personalised per user, every day.
- 10 jamams a day — each with a colour-coded success rating.
- Full Tamil Panchangam — Thithi, Yogam, Rahu Kalam, Yamagandam, Guligai.
- Location-accurate — sunrise/sunset computed for the user's coordinates.
The Solution
A full-stack platform, end to end
From database to deployment, Bhadraavel Technologies designed, built, and shipped the entire product.
Node.js + PostgreSQL back-end
Secure authentication, role-based access, and timezone-aware astronomical calculations.
Three-tier admin
User → Admin → Super Admin, so the team runs the entire operation from the browser — no developer in the loop.
Production deployment
VPS with Docker Compose behind Traefik + Let's Encrypt SSL, live at panchapatchi.co.in.
