O Pen of the Most High! Say: O people of the world! We have enjoined upon you fasting during a brief period, and at its close have designated for you Naw-Rúz as a feast. Thus hath the Day-Star of Utterance shone forth above the horizon of the Book as decreed by Him Who is the Lord of the beginning and the end. Let the days in excess of the months be placed before the month of fasting. We have ordained that these, amid all nights and days, shall be the manifestations of the letter Há, and thus they have not been bounded by the limits of the year and its months. It behoveth the people of Bahá, throughout these days, to provide good cheer for themselves, their kindred and, beyond them, the poor and needy, and with joy and exultation to hail and glorify their Lord, to sing His praise and magnify His Name; and when they end -- these days of giving that precede the season of restraint -- let them enter upon the Fast. Thus hath it been ordained by Him Who is the Lord of all mankind. The traveller, the ailing, those who are with child or giving suck, are not bound by the Fast; they have been exempted by God as a token of His grace. He, verily, is the Almighty, the Most Generous.
Let the days in excess of the months be placed before the month of fasting.
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. For further details see the section on the Bahá’í calendar in The Bahá’í World, volume XVIII.
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.
