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.

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:
Claude Code — run once:

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.
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.
