  The Baháʼí calendar is composed of nineteen months, each with nineteen days. The intercalary days, known as Ayyám-i-Há, occur between the eighteenth and nineteenth months.
  
  The names of the months were adopted by the Báb from the Du'ay-i-Sahar, a Ramadan dawn prayer by Imam Muhammad al-Baqir, the fifth Imam of Twelver Shiʻah Islam. These month names are considered to be referring to attributes of God.
  
  In the Persian Bayan the Báb divides the months into four groups known as "fire", "air", "water" and "earth" – which are three, four, six and six months long respectively. Robin Mirshahi suggests a possible link with four realms described in Baháʼí cosmology. Ismael Velasco relates this to the " arc of ascent ".
  
  In the following table, the Gregorian date indicates the first full day of the month when Naw-Rúz coincides with 21 March. The month begins at sunset of the day previous to the one listed.
