## Documentation & README

# 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 ⚡.

## Subscribe

Visit the landing page to pick your city and calculation system and copy your `webcal://` URL:

**[panchangam.astrochaganti.com](https://panchangam.astrochaganti.com)**

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](https://github.com/socraticsurge/telugu-calendar-utilities/blob/HEAD/docs/reference/53-birth-profile-calculation.md).
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](https://github.com/socraticsurge/telugu-calendar-utilities/blob/HEAD/docs/reference/54-muhurtam-election-chart-screening.md).

## 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`:

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

**Claude Code** — run once:

```bash
claude mcp add panchangam -- uvx mcp-server-panchangam
```

## 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](https://github.com/users/socraticsurge/projects/2)**.
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](https://github.com/socraticsurge/telugu-calendar-utilities/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](https://github.com/socraticsurge/telugu-calendar-utilities/blob/HEAD/docs/README.md)** for where current reference,
operations, decisions, and historical material belong, then use the
**[computation reference index](https://github.com/socraticsurge/telugu-calendar-utilities/blob/HEAD/docs/reference/README.md)** 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.
