stivals, and in the two other Festivals that fall on the twin days #110

This passage establishes four great festivals of the Baha'i year. The two
designated by Baha'u'llah as "the two Most Great Festivals" are, first,
the Festival of Ridvan, which commemorates Baha'u'llah's Declaration of
His Prophetic Mission in the Garden of Ridvan in Bag{~COMBINING MACRON BELOW~}h{~COMBINING MACRON BELOW~}dad during twelve
days in April/May 1863 and is referred to by Him as "the King of
Festivals" and, second, the Bab's Declaration, which occurred in May 1844
in S{~COMBINING MACRON BELOW~}h{~COMBINING MACRON BELOW~}iraz. The first, ninth and twelfth days of the Festival of Ridvan
are Holy Days (Q and A 1), as is the day of the Declaration of the Bab.

The "two other Festivals" are the anniversaries of the births of
Baha'u'llah and the Bab. In the Muslim lunar calendar these fall on
consecutive days, the birth of Baha'u'llah on the second day of the month
of Muharram 1233 A.H. (12 November 1817), and the birth of the Bab 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 Baha'u'llah states
that these two days are accounted as one in the sight of God (Q and A 2).
He states that, should they fall within the month of fasting, the command
to fast shall not apply on those days (Q and A 36). Given that the Baha'i
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.

139. the first day of the month of Baha #111

In the Baha'i calendar the first month of the year and the first day of
each month are given the name "Baha". The day of Baha of the month of Baha
is thus the Baha'i New Year, Naw-Ruz, which was ordained by the Bab as a
festival and is here confirmed by Baha'u'llah (see notes 26 and 147).

In addition to the seven Holy Days ordained in these passages of the
Kitab-i-Aqdas, the anniversary of the Martyrdom of the Bab was also
commemorated as a Holy Day in the lifetime of Baha'u'llah and, as a
corollary to this, 'Abdu'l-Baha added the observance of the Ascension of
Baha'u'llah, 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-Baha. See the
section on the Baha'i calendar in The
