The Kitáb-i-Aqdas - The Most Holy Book
Index term: months of year named for, under Names and attributes of; God
The number of months in a year, appointed in the Book of God, is nineteen.
The Bahá'í year, in accordance with the Badí' calendar, consists of nineteen months of nineteen days each, with the addition of certain intercalary days (four in an ordinary year and five in a leap year) between the eighteenth and nineteenth months in order to adjust the calendar to the solar year. The Báb named the months after certain attributes of God. The Bahá'í New Year, Naw-Rúz, is astronomically fixed, coinciding with the March equinox (see note 26). For further details, including the names of the days of the week and the months, see the section on the Bahá'í calendar in The Bahá'í World, volume XVIII.
