The Kitáb-i-Aqdas - The Most Holy Book
Index term: Calendar, Bahá'í
k16.
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.

The number of months in a year, appointed in the Book of God, is nineteen. Of these the first hath been adorned with this Name which overshadoweth the whole of creation.

and at its close have designated for you Naw-Rúz as a feast
The Báb introduced a new calendar, known now as the Badí' or Bahá'í <span class="highlight">calendar (see notes 27 and 147). According to this calendar, a day is the period from sunset to sunset. In the Bayán, the Báb ordained the month of 'Alá' to be the month of fasting, decreed that the day of Naw-Rúz should mark the termination of that period, and designated Naw-Rúz as the Day of God. Bahá'u'lláh confirms the Badí' calendar wherein Naw-Rúz is designated as a feast.
Naw-Rúz is the first day of the new year. It coincides with the spring equinox in the northern hemisphere, which usually occurs on 21 March. Bahá'u'lláh explains that this feast day is to be celebrated on whatever day the sun passes into the constellation of Aries (i.e. the vernal equinox), even should this occur one minute before sunset (Q&A 35). Hence Naw-Rúz could fall on 20, 21, or 22 March, depending on the time of the equinox.
Bahá'u'lláh has left the details of many laws to be filled in by the Universal House of Justice. Among these are a number of matters affecting the Bahá'í <span class="highlight">calendar. The Guardian has stated that the implementation, worldwide, of the law concerning the timing of Naw-Rúz will require the choice of a particular spot on earth which will serve as the standard for the fixing of the time of the spring equinox. He also indicated that the choice of this spot has been left to the decision of the Universal House of Justice.

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 <span>span class="highlight">calendar in The Bahá'í span>World, volume XVIII.

All Feasts have attained their consummation in the two Most Great Festivals, and in the two other Festivals that fall on the twin days
This passage establishes four great festivals of the Bahá'í span>year. The two designated by Bahá'u'lláh as "the two Most Great Festivals" are, first, the Festival of Ridván, which commemorates Bahá'u'lláh's Declaration of His Prophetic Mission in the Garden of Ridván in Baghdád during twelve days in April/May 1863 and is referred to by Him as "the King of Festivals" and, second, the Báb's Declaration, which occurred in May 1844 in Shíráz. The first, ninth and twelfth days of the Festival of Ridván are Holy Days (Q&A 1), as is the day of the Declaration of the Báb.
The "two other Festivals" are the anniversaries of the births of Bahá'u'lláh and the Báb. In the Muslim lunar calendar these fall on consecutive days, the birth of Bahá'u'lláh on the second day of the month of Muharram 1233 A.H. (12 November 1817), and the birth of the Báb on the first day of the same month 1235 A.H. (20 October 1819), respectively. They are thus referred to as the "Twin Birthdays" and Bahá'u'lláh states that these two days are accounted as one in the sight of God (Q&A 2). He states that, should they fall within the month of fasting, the command to fast shall not apply on those days (Q&A 36). Given that the Bahá'í <span>span class="highlight">calendar (see notes 26 and 147) is a solar calendar, it remains for the Universal House of Justice to determine whether the Twin Holy Birthdays are to be celebrated on a solar or lunar basis.

the first day of the month of Bahá
In the Bahá'í <span class="highlight">calendar the first month of the year and the first day of each month are given the name "Bahá". The day of Bahá of the month of Bahá is thus the Bahá'í New Year, Naw-Rúz, which was ordained by the Báb as a festival and is here confirmed by Bahá'u'lláh (see notes 26 and 147).
In addition to the seven Holy Days ordained in these passages of the Kitáb-i-Aqdas, the anniversary of the Martyrdom of the Báb was also commemorated as a Holy Day in the lifetime of Bahá'u'lláh and, as a corollary to this, 'Abdu'l-Bahá added the observance of the Ascension of Bahá'u'lláh, making nine Holy Days in all. Two other anniversaries which are observed, but on which work is not suspended, are the Day of the Covenant and the anniversary of the Passing of 'Abdu'l-Bahá. See the section on the Bahá'í <span class="highlight">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 <span class="highlight">calendar in The Bahá'í World, volume XVIII.
