Unofficial community tool, not an official Bahá'í service. Dates are based on Wondrous Badí' (https://wondrous-badi.today). Dates and sunset times follow the public Wondrous Badíʿ calendar at wondrous-badi.today.
What you may do
You may call this server to read Badíʿ dates, Holy Days, Feasts, and Fast times. There is no account and no fee. The tools are read-only.
What to rely on
A Badíʿ day begins at sunset. A city name or rough coordinates are enough for sunrise and sunset; precise GPS is not required. If a response says the times are approximate, do not use them to begin or end the Fast. Ask for a city instead. Wondrous treats dates through 221 BE (2064) as established. Later years come from extended tables through 1000 BE and may change.
No warranty
This is offered as-is, without a warranty of accuracy or availability. It is not a publication of the Universal House of Justice or of any Bahá’í institution. Confirm dates that matter to a community with a National Spiritual Assembly or with Wondrous Badíʿ.
Acceptable use
Do not send personal information you would not want a hosting provider to see in operational logs. The application itself does not ask for names, messages, or accounts, and it does not store tool arguments.
