TheBaháʼí calendar used in theBaháʼí Faith is asolar calendar consisting of nineteen months and four or fiveintercalary days, withnew year at the moment of Northern springequinox. Each month is named after a virtue (e.g., Perfection, Mercy), as are the days of the week. The first year is dated from1844 CE, the year in which theBáb began teaching.
Years on the calendar are annotated with thedate notation of BE (Baháʼí Era). The Baháʼí year 182 BE started on 20 March 2025.
The Baháʼí calendar started from the original Badíʿ calendar, created by theBáb in theKitábu'l-Asmáʼ[1] and thePersian Bayán (5:3) in the 1840s.[2] An early version of the calendar began to be implemented during his time.[3] It used a scheme of nineteen months of nineteen days, with the product of 361 days, plus intercalary days to make the calendar asolar calendar. The first day of the early implementation of the calendar year wasNowruz,[4] while the intercalary days were assigned differently than the later Baháʼí implementation. The calendar contains many symbolic meanings and allusions[5] including connections to prophecies of the Báb about the nextManifestation of God termedHe whom God shall make manifest.[6]
Baháʼu'lláh, the founder of the Baháʼí Faith, who claimed to be the one prophesied by the Báb, confirmed and adopted this calendar. Around 1870, he instructedNabíl-i-Aʻzam, the author ofThe Dawn-Breakers, to write an overview of the Badíʿ calendar.[7] In theKitáb-i-Aqdas (1873) Baháʼu'lláh madeNaw-Rúz the first day of the year, and also clarified the position of the Intercalary days to immediately precede the last month.[2][8] Baháʼu'lláh set Naw-Rúz to the day on which thesun passes into the constellation Aries. Baháʼís interpret this formula as a specification of thevernal equinox, though where that should be determined was not defined.[8]
The calendar was first implemented in the West in 1907.[9]
The Baháʼí scriptures left some issues regarding the implementation of the Badíʿ calendar to be resolved by theUniversal House of Justice before the calendar can be observed uniformly worldwide.[citation needed]
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,[10] coinciding with the completion of the ninth cycle of the calendar (see below).[11] Before that time, the Baháʼí calendar was synchronized to theGregorian calendar by starting the year at sunset on March 20, regardless of when the vernal equinox technically occurs, meaning that the extra day of a leap year occurred simultaneously in both calendars. The intercalary days always stretched from 26 February to 1 March, automatically including the Gregorian leap day so that there were four intercalary days in a regular year, and five in a Gregorian leap year.[12] TheUniversal House of Justice selectedTehran, the birthplace ofBaháʼu'lláh, as the location at which the time and date of thevernal equinox is to be determined according to astronomical tables from reliable sources.[7][10][13] These changes, which "unlocked" the Badíʿ calendar from the Gregorian calendar, came into effect at the start of year 172 BE.[7][14]
As the nameBadíʿ(wondrous orunique) suggests, the Baháʼí calendar is indeed a unique institution in the history of human culture. SociologistEviatar Zerubavel notes that the nineteen-day cycle creates a distinctive rhythm which enhances group solidarity. (Zerubavel argues that the nineteen-day cycle is more properly defined as aweek, rather than amonth, because it bears "no connection whatsoever" to thelunar cycle.) Furthermore, by finding the closest approximation of thesquare root of the annual cycle, Baháʼís "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."[15]
Years in the Baháʼí calendar are counted from Thursday 21 March 1844, the beginning of the BaháʼíEra or Badíʿ Era (abbreviatedBE orB.E.).[16] 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.
The first day of each year (Naw-Rúz) is the day (from sunset to sunset) inTehran containing the moment of thevernal equinox. This is determined in advance by astronomical computations from reliable sources.[10]
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.[18]
The Baháʼí calendar is composed of nineteen months, each with nineteen days.[19] The intercalary days, known asAyyám-i-Há, occur between the eighteenth and nineteenth months.
In thePersian Bayan the Báb divides the months into four groups known as "fire", "air", "water" and "earth" – which are three, four, six and six months long respectively.[22] Robin Mirshahi suggests a possible link with four realms described inBaháʼí cosmology.[5] Ismael Velasco relates this to the "arc of ascent".[23]
In the following table, the Gregorian date indicates the first full day of the month when Naw-Rúz coincides with 21 March. The month begins at sunset of the day previous to the one listed.

The introduction ofintercalation marked an important break fromIslam, as under theIslamic calendar the practice of intercalation had been specifically prohibited in theQurʼan.[2]
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 annualNineteen Day Fast is held during the final month of ʻAláʼ. The month of fasting is followed byNaw-Rúz, the new year.
The monthlyNineteen Day Feast is celebrated on the first day of each month, preferably starting any time between the sunset on the eve of the day to the sunset ending the day.
The nineteen days in a month have the same names as the months of the year (above), so, for example, the 9th day of each month is Asmá, or "Names".[25][26]
The Baháʼí week starts on Saturday, and ends on Friday.[27] As inJudaism andIslam, days begin at sunset and end at sunset of the following solar day. Baháʼí writings indicate that Friday is to be kept as a day of rest.[28][29] 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 Baháʼís confirmed it does not currently keep this practice.[30]
Also existing in the Baháʼí calendar system is a nineteen-year cycle called Váḥid and a 361 year (19×19) supercycle called Kull-i-S͟hayʼ (literally, "All Things").[27] The expression Kull-i-Shayʼ was used frequently by theBáb.[31] It has its origins inSufism and the significance of the numbers 19 and 361 were possibly already associated byIbn Arabi (1165–1240).[31]
Each of the nineteen years in a Vahid has been given a name as shown in the table below.[27] The tenth Váḥid of the 1st Kull-i-S͟hayʼ started on 21 March 2015, and the eleventh Váḥid will begin in 2034.[32]
The current Baháʼí year, year 182 BE (20 March 2024 – 20 March 2025), is the year Bahháj of the tenth Váḥid of the first Kull-i-S͟hayʼ.[32] The second Kull-i-S͟hayʼ will begin in 2205.[32]
The concept of a nineteen-year cycle has existed in some form since the fourth century BCE. TheMetonic cycle represents an invented measure that approximately correlates solar and lunar markings of time and which appears in several calendar systems.
