Telugu Calendar Utilities

Telugu Panchangam Calendar Feeds

Subscribable Telugu Panchangam feeds for 22 cities — delivered as .ics files you can add to Google Calendar, Apple Calendar, or Outlook.

Every day appears as an all-day event (no calendar blocking) with full Panchangam details in the description. Festival days — Ugadi, Vinayaka Chavithi, Deepavali, Maha Shivaratri, the Sankranti cluster, and 30+ more — are marked with 🪔 in the title; other special days (Ekadashi, Amavasya, Pournami, Pradosham, Sankranti, Eclipses) with ⚡.

The site is also a daily toolkit: Today's Panchangam (any date, any city), Tarabalam · Muhurtam (good days and ranked time slots for up to four people by birth star, with Chandrabalam), and the Gochara chart with Rasi Phalalu (South Indian chart, transit verdicts and a computed daily reading). Guests can also create browser-local profiles from known astrology details. Local development and an explicitly activated public build can calculate Nakshatra, Padam, Janma Rashi, Lagna, and a reviewable D1 chart from date, exact time, and birthplace. Public builds fail closed until the licensed calculation service and place provider are approved; saved calculated profiles remain viewable. The name never leaves the browser. See the calculation and privacy contract. Drik Muhurtam searches also contain a source-backed candidate-time chart post-screen, guarded by an independent fail-closed flag. Public builds make no chart request unless VITE_ELECTION_CHART_API_ENABLED is exactly true; see the screening method and release boundary. Everything is shareable to WhatsApp.

Calculation Systems

MCP Server

mcp-server-panchangam is available on PyPI. It's a standard MCP stdio server (uvx mcp-server-panchangam), so it works with any MCP-compatible client or agent — Claude Desktop, Claude Code, Cursor, Windsurf, and custom agents built on the MCP SDK. Below are examples for a couple of common clients; for others, point your client's MCP config at the same uvx mcp-server-panchangam command.

Claude Desktop — add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "panchangam": {
      "command": "uvx",
      "args": ["mcp-server-panchangam"]
    }
  }
}

Claude Code — run once:

claude mcp add panchangam -- uvx mcp-server-panchangam

Utility

All tools accept any free-text city name. Pre-configured cities resolve instantly; any other city is geocoded via OpenStreetMap. You can also pass latitude, longitude, and timezone directly.

Drik-system tools that accept a city or date also accept ayanamsa=lahiri|raman|krishnamurti|true_chitrapaksha (default: lahiri). Full API documentation and parameter details: mcp-server-panchangam on PyPI.

How it works

Feeds are generated on the 1st of every month via GitHub Actions, covering 18 months ahead. They are served as static .ics files from GitHub Pages — zero hosting cost.

GitHub Actions (monthly cron)
  → python -m telugu_panchangam.generate   (22 cities × 3 systems = 66 feeds)
  → feeds/*.ics
  → GitHub Pages (webcal:// subscriptions)

Maintenance and roadmap

The active maintenance queue is the Telugu Calendar Utilities GitHub Project. Use the linked status and priority fields to see what is planned, in progress, or ready for review. File defects and feature proposals in repository Issues.

The CSV files and phase plans under docs/tracking/ are preserved historical records; they are not a second backlog.

Documentation

The repository is the canonical documentation source. Start with the documentation standard for where current reference, operations, decisions, and historical material belong, then use the computation reference index for the detailed system map. A searchable VitePress projection is built from these files at /docs/; it is disposable presentation output and does not replace the repository as the source of truth.
