Badíʿ calendar

Unofficial community tool, not an official Bahá'í service. Dates are based on Wondrous Badíʿ.

The server answers questions about the Badíʿ date, Holy Days, the Nineteen Day Feast, and sunrise and sunset during the Fast. A Badíʿ day begins at sunset. There is no sign-in.

Endpoint

Streamable HTTP, stateless, JSON responses:

POST /mcp

Also /health, /terms, and /privacy.

Tools

• get_today — the Badíʿ date for now, or for a moment you pass
• convert_date — Gregorian ↔ Badíʿ, before and after sunset
• list_holy_days — the 11 Holy Days of a year
• list_feasts — the 19 Feasts
• get_upcoming — the next Holy Days and Feasts
• get_fast_times — sunrise and sunset through the Fast

Pass a city, or rough coordinates plus a time zone, when the clock time matters. Precise GPS is not needed. A time zone alone is approximate and is not for the Fast.
