    The first day of Ridvan
    The ninth day of Ridvan
    The twelfth day of Ridvan
    The anniversary of the declaration of the Bab
    The anniversary of the birth of Bahá'u'lláh
    The anniversary of the birth of the Bab
    The anniversary of the ascension of Bahá'u'lláh
    The anniversary of the martyrdom of the Bab
    The Feast of Naw-Ruz.
NOTE: Abdu'l-Bahá, in one of His Tablets addressed to a believer of Nayriz, Iran, has written the following: "Nine days in the year have been appointed on which work is forbidden. Some of these days have been specifically mentioned in the Book. The rest follows as corollaries to the Text.... Work on the Day of the Covenant (Fete Day of 'Abdu'l-Bahá), however, is not prohibited. Celebration of that day is left to the discretion of the friends. Its observation is not obligatory. The days pertaining to the Abha Beauty (Bahá'u'lláh) and the Primal Point (the Bab), that is to say these nine days, are the only ones on which work connected with trade, commerce, industry and agriculture is not allowed. In like manner, work connected with any form of employment, whether governmental or otherwise, should be suspended."

As a corollary of this Tablet it follows that the anniversaries of the birth and ascension of 'Abdu'l-Bahá are not to be regarded as days on which work is prohibited. The celebration of these two days, however, is obligatory.

Bahá'ís in East and West, holding administrative positions, whether public or private, should exert the utmost effort to obtain special leave from their superiors to enable them to observe these nine holy days.


THE Badi Calendar (Bahá'í Calendar) has been taken by me from the "Kitab-i-Asmá," one of the works written by the Bab. As I have observed in these days that certain believers are inclined to regard the year in which Bahá'u'lláh departed from Baghdad to Constantinople as marking the beginning of the Badi' Calendar, I have requested Mirza Aqa Jan, the amanuensis of Bahá'u'lláh, to ascertain His will and desire concerning this matter. Bahá'u'lláh answered and said: 'The year sixty A.H. (1844 A.D.), the year of the Declaration of the Bab, must be regarded as the beginning of the Badi' Calendar.' The Declaration of the Bab took place on the evening preceding the fifth day of Jamidiyu'l-Avval, of the year 1260 A.H. It has been ordained that the solar calendar be followed, and that the vernal Equinox, the day of Naw-Ruz, be regarded as the New Year's Day of the Badi' Calendar. The year sixty, in which the fifth day of Jamidiyu'l-Avval coincided with the sixty-fifth day after Naw-Ruz, has accordingly been regarded as the first year of the Badi' Calendar. As in that year, the day of Naw-Ruz, the vernal Equinox, preceded by sixty-six days the date of the Declaration of the Bab, I have therefore, throughout my history, regarded the Naw-Ruz of the year sixty-one A.H. (the Naw-Ruz immediately following the Declaration of the Bab) as the first Naw-Ruz of the Badi' Calendar. I have accordingly considered the Naw-Ruz of this present year, the year 1306 A.H., which is the 47th solar year after the Declaration of the Bab, as the 46th Naw-Ruz of the Badi' Calendar.

Soon after Bahá'u'lláh had left the fortress of 'Akka and was dwelling in the house of Malik, in that city, He commanded me to transcribe the text of the Badi' Calendar and to instruct the believers in its details. On the very day in which I received His command, I composed, in verse and prose, an exposition of the main features of that Calendar and presented it to Him. The versified copy, being now unavailable, I am herein transcribing the version in prose. The days of the week are named as follows:

The names of the months, which are the same as the days of each month, are as follows:

Ayyam-i-Hi (Intercalary Days) February 26th to March 1st inclusive - four in ordinary and five in leap years.

The first day of each month is thus the day of Baha, and the last day of each month the day of 'Ala'.

The Bab has regarded the solar year, of 365 days, 5 hours, and fifty odd minutes, as consisting of 19 months of 19 days each, with the addition of certain intercalary days. He has named the New Year's Day, which is the Day of Naw-Ruz, the day of Baha, of the month of Baha. He has ordained the month of 'Ala' to be the month of fasting, and has decreed that the day of Naw-Ruz should mark the termination of that period. As the Bab did not specifically define the place for the four days and the fraction of a day in the Badi' Calendar, the people of the Bayan were at a loss as to how they should regard them. The revelation of the Kitab-i-Aqdas in the city of 'Akka resolved this problem and settled the issue. Bahá'u'lláh designated those days as the "Ayyam-i-Ha" and ordained that they should immediately precede the month of 'Ala', which is the month of fasting. He enjoined upon His followers to devote these days to feasting, rejoicing, and charity. Immediately upon the termination of these intercalary days, Baha'u'11ah ordained the month of fasting to begin. I have heard it stated that some of the people of the Bayan, the followers of Mirza Yahya, have regarded these intercalary days as coming immediately after the month of 'Ala', thus terminating their fast five days before the day of Naw-Ruz. This, notwithstanding the explicit text of the Bayan which states that the day of Naw-Ruz must needs be the first day of the mouth of Bahá, and must follow immediately after the last day of the month of 'A1a'. Others, aware of this contradiction, have started their fasting on the fifth day of the month of 'Alá', and included the intercalary days within the period of fasting.

Every fourth year the number of the intercalary days is raised from four to five. The day of Naw-Ruz falls on the 21st of March only if the vernal Equinox precedes the setting of the sun on that day. Should the vernal Equinox take place after sunset, Naw-Ruz will have to be celebrated on the following day.

The Bab has, moreover, in His writings, revealed in the Arabic tongue, divided the years following the date of His Revelation, into cycles of nineteen years each. The names of the years in each cycle are as follows:

2.Bá' B.
3.Ab Father
14.Vahháb   Bountiful
18.AbháMost Luminous
19.   VáhidUnity

Each cycle of nineteen years is called Váhid. Nineteen cycles constitute a period called Kull-i-Shay'. The numerical value of the word "Váhid" is nineteen, that of "Kull-i-Shay'" is 361. "Vahid" signifies unity, and is symbolic of the unity of God.

The Bab has, moreover, stated that this system of His is dependent upon the acceptance and good-pleasure of "Him Whom God shall make manifest." One word from Him would suffice either to establish it for all time, or to annul it forever.

For instance, the date of the 21st of April, 1930, which is the first day of Ridvan, and which according to the Kitab-i-Aqdas must coincide with the "thirteenth day of the second Bahá'í month," and which fell this year (1930) on Monday, would, according to the system of the Badi' Calendar, be described as follows:

"The day of Kamál, the day of Qudrat, of the month of Jalál, of the year Bahhaj, of the fifth Váhid, of the first Kull-i-Shay'."
