The four remaining +;; "intercalary" days are called the Ayyam-i-Ha (days of Ha), and are +;; placed between the 18th and 19th months. They are meant as a time +;; of festivals preceding the 19th month, which is the month of +;; fasting. In Gregorian leap years, there are 5 of these days (Ha +;; has the numerical value of 5 in the arabic abjad, or +;; letter-to-number, reckoning). + +;; Each month is named after an attribute of God, as are the 19 days +;; -- which have the same names as the months. There is also a name +;; for each year in every 19 year cycle. These cycles are called +;; Vahids. A cycle of 19 Vahids (361 years) is called a Kullu-Shay, +;; which means "all things". + +;; The calendar was named the "Badi calendar" by its author, the Bab. +;; It uses a week of seven days, corresponding to the Gregorian week, +;; each of which has its own name, again patterned after the +;; attributes of God. + ;; Note: The days of Ayyam-i-Ha are encoded as zero and negative ;; offsets from the first day of the final month. So, (19 -3 157) is ;; the first day of Ayyam-i-Ha, in the year 157 BE. -- 2.39.2
