;; Each month is named after an attribute of God, as are the 19 days

;; The calendar was named the "Badí` calendar" by its author, the Báb.
;; It uses a week of seven days, corresponding to the Gregorian week,
;; each of which has its own name, again patterned after the

;; Note: The days of Ayyám-i-Há are encoded as zero and negative
