The Badi (Wondrous) Calendar is a calendar designed by the Bab. This calendar tool renders the current New Age (N.A.) date overlaid with the lunations of the traditional Indian Calendar as laid out in the Guru Granth Sahib. This calendar also tracks sunset, midnight, sunrise, and solar noon with a graphic tool, and this tool may be used as a functional conversion tool between Badi and Gregorian dates. The starting date of the Badi Calendar is 1844, the year in which the New Age began.
