Web Extension

"Badíʿ Calendar"


This Web Extension shows today's date in the Badíʿ calendar, the official calendar of the Bahá'í Faith. The date shown is based on where your computer is, and on the sunset time in that area.

This is a personal initiative and project by Glen Little (glen.little@gmail.com). You can find more Badíʿ calendar tools on Facebook and on Google+

The extension works in these browsers:
  • Chrome Browser - Install for free from the Chrome Web Store and it works on Google Chrome browsers for Windows, Mac, and Chromebook. Installation takes only a few seconds. Click here to view the Badíʿ Calendar in the Web Store.
  • Firefox Browser - Install the Wondrous-Badíʿ Calendar add-on for free from the Mozilla Add-ons gallery. Works great in Firefox 57 and later. It supports almost all of the features that are in the Chrome version.

  • Edge Browser - I plan to make it available when Web Extensions are permitted in a future version.
The Extension works in a number of languages based on language your browser is using. See the Chrome Web Store entry to know which languages are available. If you would like to help translate it into another language, please see Translating the Badí' Calendar Extension.

Date Calculations

Please note that dates until 221 B.E. are derived from the document 'Bahá’í Dates 172 to 221 B.E.' prepared by the Bahá’í World Centre. 

Dates further in the future are adapted from http://www.bahaidate.today/table-of-dates. The formulas used to determine these dates may need to be updated closer to the time and as astronomical observations improve. So please don't use this extension to finalize your plans 100 years in the future!
