My God, my Fire and my Light! The days which Thou hast named the Ayyám-i-Há (the Days of Há, Intercalary Days) in Thy Book have begun, O Thou Who art the King of names, and the Fast which Thy most exalted Pen hath enjoined unto all who are in the kingdom of Thy creation to observe is approaching. I entreat Thee, O my Lord, by these days and by all such as have during that period clung to the cord of Thy commandments, and laid hold on the handle of Thy precepts, to grant that unto every soul may be assigned a place within the precincts of Thy court, and a seat at the revelation of the splendors of the light of Thy countenance.
These, O my Lord, are Thy servants whom no corrupt inclination hath kept back from what Thou didst send down in Thy Book. They have bowed themselves before Thy Cause, and received Thy Book with such resolve as is born of Thee, and observed what Thou hadst prescribed unto them, and chosen to follow that which had been sent down by Thee.
Thou seest, O my Lord, how they have recognized and confessed whatsoever Thou hast revealed in Thy Scriptures. Give them to drink, O my Lord, from the hands of Thy graciousness the waters of Thine eternity. Write down, then, for them the recompense ordained for him that hath immersed himself in the ocean of Thy presence, and attained unto the choice wine of Thy meeting.
I implore Thee, O Thou the King of kings and the Pitier of the downtrodden, to ordain for them the good of this world and of the world to come. Write down for them, moreover, what none of Thy creatures hath discovered, and number them with those who have circled round Thee, and who move about Thy throne in every world of Thy worlds.
Thou, truly, art the Almighty, the All-Knowing, the All-Informed.
The Badí‘ calendar is based on the solar year of 365 days, 5 hours, and 50 odd minutes. The year consists of 19 months of 19 days each (i.e. 361 days), with the addition of four extra days (five in a leap year). The Báb did not specifically define the place for the intercalary days in the new calendar. The Kitáb-i-Aqdas resolves this question by assigning the “excess” days a fixed position in the calendar immediately preceding the month of ‘Alá’, the period of fasting.
Known as the Ayyám-i-Há (the Days of Há), the Intercalary Days have the distinction of being associated with “the letter Há.” The abjad numerical value of this Arabic letter is five, which corresponds to the potential number of intercalary days. The letter “Há” has been given several spiritual meanings in the Holy Writings, among which is as a symbol of the Essence of God.
Bahá’u’lláh enjoined upon His followers to devote these days to feasting, rejoicing and charity. In a letter written on Shoghi Effendi’s behalf it is explained that “the intercalary days are specially set aside for hospitality, the giving of gifts, etc.”
