[ Momen, Moojan (2014)]
The Badíʻ (Baháʼí) Calendar: An Introduction
In the ''
Kitáb-i-Aqdas'' (1873) Baháʼu'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.
[.] Baháʼu'lláh set Naw-Rúz to the day on which the
sun passes into the constellation Aries. Baháʼís interpret this formula as a specification of the
vernal equinox, though where that should be determined was not defined.
The calendar was first implemented in the West in 1907.
The Baháʼí 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,
coinciding with the completion of the ninth cycle of the calendar (see below).
Before that time, the Baháʼí calendar was synchronized to the
Gregorian calendar
The Gregorian calendar is the calendar used in most parts of the world. It went into effect in October 1582 following the papal bull issued by Pope Gregory XIII, which introduced it as a modification of, and replacement for, the Julian cale ...
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.
The

vernal equinox is to be determined according to astronomical tables from reliable sources.
These changes, which "unlocked" the Badíʿ calendar from the Gregorian calendar, came into effect at the start of year 172 BE.
Significance
As the name Badíʿ (''wondrous'' or ''unique'') suggests, the Baháʼí calendar is indeed a unique institution in the history of human culture. Sociologist
Eviatar 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 a

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."
Years
Years in the Baháʼí calendar are counted from Thursday 21 March 1844, the beginning of the Baháʼí
Era or Badíʿ Era (abbreviated ''BE'' or ''B.E.'').
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

containing the moment of the
vernal equinox. This is determined in advance by astronomical computations from reliable sources.
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.

Months
The Baháʼí calendar is composed of nineteen months, each with nineteen days.
The intercalary days, known as
Ayyám-i-Há, occur between the eighteenth and nineteenth months.
The names of the months were adopted by the Báb from the
Du'ay-i-Sahar
Du'a al-Baha () (known as Du'a al-Sahar () is a Du'a recommended to Muslims to recite in pre-dawns during Ramadan, when Muslims usually eat Suhur. Since it is very common among Shia Islam, Shia, it is known Dua al-Sahar (supplication of pre-dawn) ...

Twelver Shiʻah Islam. These month names are considered to be referring to attributes of God.
In the ''
Persian 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. Robin Mirshahi suggests a possible link with four realms described in
Baháʼí cosmology.

the practice of intercalation had been specifically prohibited in the
Qurʼan.
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.

Days in a Month
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".

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").

and the significance of the numbers 19 and 361 were possibly already associated by
Ibn Arabi (1165–1240).
Each of the nineteen years in a Vahid has been given a name as shown in the table below.
The tenth Váḥid of the 1st Kull-i-S͟hayʼ started on 21 March 2015, and the eleventh Váḥid will begin in 2034.
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.
The second Kull-i-S͟hayʼ will begin in 2205.
The concept of a nineteen-year cycle has existed in some form since the fourth 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.
