Bahá'í calendar

Last updated

The Bahá'í Calendar, also called the Badíʿ Calendar (Badíʿ means wondrous or unique), [1] is a solar calendar with years composed of 19 months of 19 days each (361 days) plus an extra period of "Intercalary Days". Years begin at Naw-Rúz, on the day of the vernal equinox in Tehran, Iran, coinciding with March 20 or 21.

A solar calendar is a calendar whose dates indicate the season or almost equivalently the apparent position of the Sun relative to the stars. The Gregorian calendar, widely accepted as standard in the world, is an example of a solar calendar. The main other type of calendar is a lunar calendar, whose months correspond to cycles of Moon phases. The months of the Gregorian calendar do not correspond to cycles of Moon phase.

Intercalation or embolism in timekeeping is the insertion of a leap day, week, or month into some calendar years to make the calendar follow the seasons or moon phases. Lunisolar calendars may require intercalations of both days and months.

Naw-Rúz is the first day of the Bahá'í calendar year and one of nine holy days for adherents of the Bahá'í Faith. It occurs on the vernal equinox, on or near March 21.


The first year is dated from 21 March 1844  CE, the year during which the Báb proclaimed his religion. [2] Years are annotated with the date notation of BE (Bahá'í Era),

Common Era or Current Era (CE) is one of the notation systems for the world's most widely used calendar era. BCE is the era before CE. BCE and CE are alternatives to the Dionysian BC and AD system respectively. The Dionysian era distinguishes eras using AD and BC. Since the two notation systems are numerically equivalent, "2019 CE" corresponds to "AD 2019" and "400 BCE" corresponds to "400 BC". Both notations refer to the Gregorian calendar. The year-numbering system used by the Gregorian calendar is used throughout the world today, and is an international standard for civil calendars.

Báb Iranian prophet and founder of the religion Bábism, venerated in the Baháí Faith

The Báb, born Siyyid `Alí Muhammad Shírází was the founder of Bábism, and one of the central figures of the Bahá'í Faith.

A calendar era is the year numbering system used by a calendar. For example, the Gregorian calendar numbers its years in the Western Christian era. The instant, date, or year from which time is marked is called the epoch of the era. There are many different calendar eras such as Saka Era.

The year 176 BE started on the day of the vernal equinox (in Tehran) in 2019, that is on 21 March 2019.


The Bahá'í Calendar started from the original Badíʿ Calendar, created by the Báb in the Kitabu'l-Asmá' [3] and the Persian Bayán (5:3) in the 1840s. [4] An early version of the calendar began to be implemented during his time. [5] It used a scheme of 19 months of 19 days (19×19) for 361 days, plus intercalary days to make the calendar a solar calendar. The first day of the early implementation of the calendar year was Nowruz, [6] while the intercalary days were assigned differently than the later Bahá'í implementation. The calendar contains many symbolic meanings and allusions [7] including connections to prophecies of the Báb about the next Manifestation of God termed He whom God shall make manifest. [8]

The Kitabu'l-Asmá' or Book of Divine Names is a book written by the Báb, the founder of Bábi religion, in Arabic during his imprisonment in Máh-Kú and Chihriq in Iran (1847-1850). With a total volume of more than 3,000 pages, it is the largest revealed scripture in religious history. At least twenty-six manuscripts exist, and much of the text has not yet been located. Some extracts are available in English in the volume Selections from the Writings of the Báb.

The Persian Bayán is one of the principal scriptural writings of the Báb, the founder of Bábi religion, written in Persian. The Báb also wrote a shorter book in Arabic, known as the Arabic Bayán.

Nowruz Day of new year in the Persian calendar

Nowruz is the Iranian New Year, also known as the Persian New Year, which is celebrated worldwide by various ethno-linguistic groups.

Bahá'u'lláh, the founder of the Bahá'í Faith, who claimed to be the one prophesied by the Báb, confirmed and adopted this calendar. Around 1870, he instructed Nabíl-i-A`zam, the author of The Dawn-Breakers , to write an overview of the Badíʿ calendar. [9] In the Kitáb-i-Aqdas (1873) Bahá'u'lláh made Naw-Rúz the first day of the year, and also clarified the position of the Intercalary days to immediately precede the last month. [4] [10] Bahá'u'lláh set Naw-Rúz to the day on which the sun passes into the constellation Aries. Bahá'ís interpret this formula as a specification of the vernal equinox, though where that should be determined was not defined. [10]

Baháulláh Founder of the Baháí Faith

Bahá'u'lláh, born Mírzá Ḥusayn-`Alí Núrí, was a Persian religious leader, and the founder of the Bahá'í Faith, which advocates universal peace and unity among all races, nations, and religions.

Mullá Muḥammad-i-Zarandí, more commonly known as Nabíl-i-A’ẓam or Nabíl-i-Zarandí, was an eminent Bahá'í historian during the time of Bahá'u'lláh, and one of the nineteen Apostles of Bahá'u'lláh. He is most famous for authoring The Dawn-Breakers, which stands out as one of the most important and extensive accounts of the ministry of the Báb.

The Dawn-Breakers: Nabíl’s Narrative of the Early Days of the Bahá’í Revelation or Nabíl's Narrative (Táríkh-i-Nabíl) is a historical account of the early Bábí and Bahá'í Faiths written by Nabíl-i-A`zam in 1887–88. The English translation by Shoghi Effendi was published in 1932.

The calendar was first implemented in the West in 1907. [11]

The Bahá'í scriptures left some issues regarding the implementation of the Badíʿ calendar to be resolved by the Universal House of Justice before the calendar can be observed uniformly worldwide. On 10 July 2014 the Universal House of Justice announced provisions that will enable the common implementation of the Badíʿ calendar worldwide, beginning at sunset 20 March 2015, [12] coinciding with the completion of the ninth cycle of the calendar (see below). [13]

Before Naw-Rúz 2015

The Bahá'í Calendar in western countries was synchronized to the Gregorian calendar, meaning that the extra day of a leap year occurred simultaneously in both calendars. The intercalary days stretched from 26 February to 1 March, automatically including the Gregorian leap day. There were 4 intercalary days in a regular year, and 5 in a leap year. [14]

The practice in western countries was to start the year at sunset on March 20, regardless of when the vernal equinox technically occurs.

For eastern countries where the Islamic lunar calendar was used, the Bahá'í Calendar synchronized with the Islamic Lunar calendar. For example, the births of The Báb and of Bahá'u'lláh were commemorated according to their corresponding lunar calendar dates, which were the 1st and 2nd days, respectively, of the month of Muharram. Thus, the commemoration of these anniversaries would drift backwards about 11 days each year, and could therefore be gradually celebrated at any season (spring, winter, autumn, summer) of the year.

From Naw-Rúz 2015

In 2014, the Universal House of Justice selected Tehran, the birthplace of Bahá'u'lláh, as the location to which the date of the vernal equinox is to be fixed, thereby "unlocking" the Badíʿ calendar from the Gregorian calendar. For determining the dates, astronomical tables from reliable sources are used. [9] [12] [15]

In the same message the Universal House of Justice decided that the birthdays of the Báb and Bahá'u'lláh will be celebrated on "the first and the second day following the occurrence of the eighth new moon after Naw-Rúz" (also with the use of astronomical tables) and fixed the dates of the Bahá'í Holy Days in the Bahá'í Calendar, standardizing dates for Bahá'ís worldwide. By this decision, the Badíʿ calendar was "unlocked" from the Islamic lunar calendar, as the celebration of the birthdays of the Báb and Bahá'u'lláh are no longer connected to the month of Muharram, and therefore do not drift continually backward by about 11 days, from year to year.

These changes came into effect as of sunset on 20 March 2015. [9] [16]


As the name Badíʿ (wondrous or unique) suggests, the Bahá'í Calendar is indeed a unique institution in the history of human culture. Sociologist Eviatar Zerubavel notes that the 19-day cycle creates a distinctive rhythm which enhances group solidarity. (Zerubavel argues that the 19 day cycle is more properly defined as a week, rather than a month, because it bears "no connection whatsoever" to the lunar cycle.) Furthermore, by finding the closest approximation of the square root of the annual cycle, Bahá'ís "have managed to establish the most symmetrical relationship possible between the week and the year, which no one else throughout history has ever managed to accomplish." [17]


Years in the Bahá'í Calendar are counted from Thursday 21 March 1844, the beginning of the Bahá'í Era or Badíʿ Era (abbreviated BE or B.E.). [18] Year 1 BE thus began at sundown 20 March 1844.

The length of each year is strictly defined as the number of days between the opening and closing days of the year, with the number of intercalary days adjusted as needed. The year ends on the day before the following vernal equinox.

Vernal Equinox

The first day of each year (Naw-Rúz) is the day (from sunset to sunset) in Tehran containing the moment of the vernal equinox. This is determined in advance by astronomical computations from reliable sources. [12]

Since the Gregorian calendar is not tied to the equinox, the Gregorian calendar shifts around by a day or two each year, as shown in the following table. [19]

The Bahá'í Calendar is composed of 19 months, each with 19 days. [2] The Nineteen Day Fast is held during the final month of ‘Alá’, and is preceded by the intercalary days, known as Ayyám-i-Há. The month of fasting is followed by Naw-Rúz, the new year.

Month names

The names of the months were adopted by the Báb from the Du'ay-i-Sahar, a Ramadan dawn prayer by Imam Muhammad al-Baqir, the fifth Imam of Twelver Shi'ah Islam. [20] [21] These month names are considered to be referring to attributes of God.

In the Persian Bayan the Báb divides the months in four groups, of three, four, six and six months respectively. [22] Robin Mirshahi suggests a possible link with four realms described in Bahá'í cosmology. [7]

The days of the month have the same names as the names of the month – the 9th day of the month for example is the same as the 9th month – Asmá, or "Names". In the following table, the Gregorian date indicates the first full day of the month. The month begins at sunset of the Gregorian date previous to the one listed, after which time that month's Nineteen Day Feast may be celebrated.

The introduction of intercalation marked an important break from Islam, as under the Islamic calendar the practice of intercalation had been specifically prohibited in the Qur'an. [4]

The number of the intercalary days is determined in advance to ensure that the year ends on the day before the next vernal equinox. This results in 4 or 5 intercalary days being added. These days are inserted between the 18th and 19th months, falling around the end of February in the Gregorian calendar. The number of days added is unrelated to the timing of the Gregorian leap year.


The Bahá'í week starts on Saturday, and ends on Friday. [23] Like Judaism and Islam, days begin at sunset and end at sunset of the following solar day. Bahá'í writings indicate that Friday is to be kept as a day of rest. [24] [25] The practice of keeping Friday as a day of rest is currently not observed in all countries; for example, in the UK, the National Spiritual Assembly of the Bahá'ís confirmed it does not currently keep this practice. [26]

Also existing in the Bahá'í Calendar system is a 19 year cycle called Váḥid and a 361 year (19×19) supercycle called Kull-i-Shay’ (literally, "All Things"). [23] Each of the 19 years in a Vahid has been given a name as shown in the table below. [23]

The 10th Váḥid of the 1st Kull-i-Shay' started on 21 March 2015, and the 11th Váḥid will begin in 2034. [27]

The current Bahá'í year, year 176 BE (21 March 2019 – 20 March 2020), is year Báb (Gate) of the 10th Váḥid of the 1st Kull-i-Shay'. [27] The 2nd Kull-i-Shay' will begin in 2205. [27]

The concept of a 19-year cycle has existed in some form since the 4th century  BCE. The Metonic cycle represents an invented measure that approximately correlates solar and lunar markings of time and which appears in several calendar systems.

Riḍván is a twelve-day festival in the Bahá'í Faith, commemorating Bahá'u'lláh's declaration that he was a Manifestation of God. In the Bahá'í Calendar, it begins at sunset on the 13th of Jalál, which translates to the 20th or 21st of April, depending on the date of the March equinox. On the first, ninth and twelfth days of Ridván, work and school should be suspended.

The following is a basic timeline of the Bábí and Bahá'í religions emphasizing dates that are relatively well known. For a more comprehensive chronology of the timeline, see the references at the bottom.

Shrine of the Báb Tomb of the founder of the Bábí Faith in Haifa, Israel

The Shrine of the Báb is a structure in Haifa, Israel where the remains of the Báb, founder of the Bábí Faith and forerunner of Bahá'u'lláh in the Bahá'í Faith, have been buried; it is considered to be the second holiest place on Earth for Bahá'ís, after the Shrine of Bahá'u'lláh in Acre. Its precise location on Mount Carmel was designated by Bahá'u'lláh himself to his eldest son, `Abdu'l-Bahá, in 1891. `Abdu'l-Bahá planned the structure, which was designed and completed several years later by his grandson, Shoghi Effendi.

March equinox the equinox on the earth when the Sun appears to leave the southern hemisphere and cross the celestial equator

The March equinox or Northward equinox is the equinox on the Earth when the subsolar point appears to leave the Southern Hemisphere and cross the celestial equator, heading northward as seen from Earth. The March equinox is known as the vernal equinox in the Northern Hemisphere and as the autumnal equinox in the Southern.

Badí' was the title of Mírzá Áqá Buzurg-i-Nishapuri, also known by the title the Pride of Martyrs. He was the son of `Abdu'l-Majid-i-Nishapuri, a follower of the Báb and Bahá'u'lláh.

Bahá'í laws are laws and ordinances used in the Bahá'í Faith and are a fundamental part of Bahá'í practice. The laws are based on authenticated texts from Bahá'u'lláh, the founder of the Bahá'í Faith, and also includes subsequent interpretations from `Abdu'l-Bahá and Shoghi Effendi, and legislation by the Universal House of Justice. Bahá'í law is presented as a set of general principles and guidelines and individuals must apply them as they best seem fit. While some of the social laws are enforced by Bahá'í institutions, the emphasis is placed on individuals following the laws based on their conscience, understanding and reasoning, and Bahá'ís are expected to follow the laws for the love of Bahá'u'lláh. The laws are seen as the method of the maintenance of order and security in the world.

The Apostles of Bahá'u'lláh were nineteen eminent early followers of Bahá'u'lláh, the founder of the Bahá'í Faith. The apostles were designated as such by Shoghi Effendi, head of the religion in the earlier half of the 20th century, and the list was included in The Bahá'í World, Vol. III (pp. 80–81).

Bahá'í literature, like the literature of many religions, covers a variety of topics and forms, including scripture and inspiration, interpretation, history and biography, introduction and study materials, and apologia. Sometimes considerable overlap between these forms can be observed in a particular text.

The Nineteen-Day Fast is a nineteen-day period of the year, during which members of the Bahá'í Faith adhere to a sunrise-to-sunset fast. Along with obligatory prayer, it is one of the greatest obligations of a Bahá'í, and its chief purpose is spiritual; to reinvigorate the soul and bring the person closer to God. The fast was instituted by the Báb, and accepted by Bahá'u'lláh, the founder of the Bahá'í Faith, who stated its rules in his book of laws, the Kitáb-i-Aqdas. The nineteen days of fasting occur immediately before the beginning of the Bahá'í New Year, on the vernal equinox.

The Bahá'í Faith has eleven holy days, which are important anniversaries in the history of the religion. On nine of these holy days, work is suspended. There is no fixed format for any of the holy days, and Bahá’í communities organize their own commemorative meetings.

Ayyám-i-Há refers to a period of intercalary days in the Bahá'í calendar, when Bahá'ís celebrate the Festival of Ayyám-i-Há. The four or five days of this period are inserted between the last two months of the calendar. The length of Ayyám-i-Há varies according to the timing of the following vernal equinox so that the next year always starts on the vernal equinox.

Birth of Baháulláh Baháí religious observance; the birthday of Baháulláh

The Birth of Bahá'u'lláh is one of nine holy days in the Bahá'í calendar that is celebrated by Bahá'ís and during which work is suspended. The holy day celebrates the birth of Bahá'u'lláh, the founder of the Bahá'í Faith. The 2017 date is October 22.

The Day of the Covenant is the day when Bahá'ís celebrate the appointment of `Abdu'l-Bahá as the Centre of Baha'u'llah's Covenant. It occurs yearly on the 4th day of Speech (Qawl) which coincides with either November 25 or 26 depending on when Naw Ruz falls on that year. The 2016 date is November 25.

Maid of Heaven refers to a vision that Bahá’u’lláh, founder of the Bahá'í Faith was said to have had of a maiden from God, through whom he received his mission as a Manifestation of God.

Zoroastrianism is recognized in the Bahá'í Faith as one of nine known religions and its scriptures are regarded as predicting the coming of Bahá'u'lláh. Zoroaster is included in the succession of Manifestations of God. The authenticity of the Zend Avesta is seen as uncertain.

The following outline is provided as an overview of and a topical guide to the Bahá'í Faith.

The Festivals of the Twin Birthdays or the Twin Holy Birthdays refers to two successive holy days in the Bahá'í Calendar that celebrate the births of two central figures of the Bahá'í Faith. The two holy days are the birth of the Báb on the first day of Muharram in the Islamic calendar and the birth of Bahá'u'lláh on the second day of Muharram.
