A lunisolar calendar of the Arabian Peninsula before Islam. The period when Ramaḍān still marked the scorching heat, Jumādā the dried-up water, and Rabīʿ the spring pasture. The calendar in which the Bedouin read the sky as a web of rain-and-star relations, the poet wrote of the Pleiades as an image of the night, and the soothsayer watched Suhayl as the breaker of the season. A reconstruction whose primary source is poetry.
The pre-Islamic Arab calendar disappeared without leaving behind a clear Mesopotamian-style tablet corpus. No systematic astronomical text comparable to Babylon's MUL.APIN, Egypt's decan lists, or the Greek parapegma has reached us from the pre-Islamic era. Yet there is an enormous archive that tells us how this calendar worked, which stars brought which rains, and which season each month name carried: pre-Islamic Arabic poetry. The Muʿallaqāt, the Mufaḍḍaliyyāt, the Dīwān of the Hudhayl, the Aṣmaʿiyyāt. Hundreds of poets, tens of thousands of verses. Each one filled with stars, months, rains, storms.
When the poet says Jumādā, he means dried-up water; when he says Rabīʿ, he means pasture; when he says Ramaḍān, he means scorching heat. But note: the pre-Islamic poet does not name the month directly. A line such as "Shaʿbān arrived and my camels grew thirsty" simply does not exist in the canon. The poet instead names the season through a star, a rainfall, a pasture, an abandoned campsite. Imruʾ al-Qays likens the Pleiades to the pearls on a woman's sash; Labīd has the spring constellations' rains wash the traces of the campsite; Abū Dhuʾayb uses al-Jabbār (Orion) as the orienting marker of the night hunt. Because these verses do not directly name a month, they are not weaker testimony; on the contrary, they are stronger, because they are first-hand documents that keep the calendar alive in its imagistic language.
This tool reconstructs that system in the light of poetry. In the year you select, the twelve months are laid out in sequence; for each month the etymology, the seasonal meaning, the verse fragments attributed to it where available, and the corresponding manāzil al-qamar (the twenty-eight lunar mansions) and anwāʾ (star-rain relations) are shown. The ashhur al-ḥurum (the four sacred months) are highlighted in gold; during these months warfare and blood feud were suspended. The pilgrimage and fair cycle, stretching from Dhū al-Qaʿda to Muḥarram, is mapped as a single religious-economic season. The nasīʾ debate places the classical Islamic astronomers' interpretation as intercalation (al-Bīrūnī, Abū Maʿshar) alongside the modern orientalist reading as the displacement of the sacred months (Mahmud Effendi, de Blois).
Modern academic scholarship (especially the two landmark 1993 books by Suzanne and Jaroslav Stetkevych) reads the pre-Islamic qaṣīda as a calendrical-ritual structure in its very form. The poet does not name a month because the qaṣīda itself (aṭlāl-raḥīl-fakhr) is the poetic architecture of the seasonal cycle. The section The Calendrical Structure of Poetry grounds this reading in four pilot cases: the cycle of sacred and profane months, the lyric expression of the anwāʾ system, the Pleiades as a temporal stamp, and the geographical anwāʾ map of Imruʾ al-Qays' storm scene.
The cuneiform tablets of Babylon, the stone walls of Egypt, the philosophical texts of Greece, the official Roman records — none of these are here. In their place stand the elegy of the sons of Hudhayl, Imruʾ al-Qays' secret visit to his beloved, and the empty traces of tents Labīd finds at Minā. Poetry is the language of the calendar; the pre-Islamic Arabs' own system for recording the sky.
The Meccan calendar of the pre-Islamic era. Each month begins with the first sighting of the new crescent in the sky of the Hejaz. Four months are ḥarām; in these months war and blood feud are taboo, and the fairs near the Kaʿba carry the economy of this inviolability. Click to see the etymology, the poetic record, the corresponding lunar mansions, and the anwāʾ star-rain pairings.
The sacred status of Dhū al-Qaʿda, Dhū al-Ḥijja, and Muḥarram rests not only on a religious but also on an economic logic. For three months, the fairs around the Kaʿba (ʿUkāẓ, Majannah, Dhū al-Majāz) gather tribes from across the Arabian Peninsula. Blood feud is suspended; trade, poetry, divination, and marriage are organised during this season.
In its sidereal cycle the Moon lodges each night in a different constellation. There are twenty-eight mansions; in each one, the period of the Moon's conjunction with the Sun is linked to particular rains or winds. The system is parallel to the Indian nakshatra and the Chinese xiu; their shared origin is most likely Mesopotamian. In the pre-Islamic era it lived as the anwāʾ system; with Islam, astrological and mystical layers (Ibn ʿArabī's al-Futūḥāt) were added.
The stars the poet invokes most often. Each carries its own season, its own image, its own rain. These are at the same time the sky of Babylon, of Greece, and of India; the same star is named with the same function in three languages.
The Qurʾān (Tawba 36-37) strictly forbids nasīʾ ("postponement"). This prohibition confirms that an active practice existed in the pre-Islamic period. But what that practice was is still disputed. Two main interpretations.
The pre-Islamic Arabs, in a manner similar to the Jewish calendar, added a thirteenth month every two or three years. This anchored the calendar to the seasons; it kept Ramaḍān in summer and Rabīʿ in spring. Nasīʾ was the name of this intercalation.
In al-Āthār al-bāqiya, al-Bīrūnī mentions an intercalation decision announced during the pilgrimage season by an official (the qalammas or nāsiʾ) of the Banū Kināna tribe. A nineteen-year cycle with seven intercalations (similar to the Metonic cycle) or a twelve-year cycle with four intercalations have been proposed.
The strongest argument in favour of this interpretation is poetic: in the last century before Islam, the month names were used in active accord with their seasonal meanings. A pure lunar calendar would invert the seasons over 33 years, but no such drift is visible in the poetry.
Nasīʾ was not an intercalation but the practice of shifting the position of the sacred months. When tribes wished to pursue a blood feud, they would push the Muḥarram of a given year onto Ṣafar, and so the identity of the "forbidden" time was manipulated. The pilgrimage too could then fall in a different season because of this shift.
Evidence for this interpretation comes from an early Sabaean inscription: the verb nsʾw is used in the sense of "postponing a religious rite because of war"; not intercalation, but the postponement of an event.
If this view is correct, by the early years of Islam the Arab calendar was already purely lunar. The prohibition of nasīʾ only halted a social manipulation; it was not a calendar reform. This reading, however, is hard to reconcile with the poetic evidence.
With Islamic history, the Hijri years (1 AH = 1 Muḥarram, 622 CE) were standardised under ʿUmar. The Hijri calendar is purely lunar; no nasīʾ is used. As a result, Ramaḍān can fall in any season; the original seasonal meaning of the month names today is an etymological heritage.
"It is only dahr that destroys us."
A common pre-Islamic motif · recurring in Labīd, Zuhayr, and many other poets
Dahr (دَهْر) and zamān (زَمَان) are the central concepts of fate in pre-Islamic poetry. An invisible, impersonal, unquestionable force; passing time that consumes everything. This resembles the Hellenistic heimarmene or the Roman fatum, but it lives without an astronomical technique, as an intuitive-poetic faith in fate. The stars are the witnesses of dahr; the rains are its seals. With the coming of Islam, the role of dahr is theologically redefined; a hadith — "Do not curse dahr, for God is dahr" — binds the blind time of pre-Islamic poetry to divine will. One of the critical points in the poetic-religious transition. Time perception here is not theological but cosmological; the stars and seasons are the visible face of dahr, and human life is only a brief line of its record.
Why does the pre-Islamic poet never directly name a month, yet his entire poem carries a calendrical structure? The verse, the season, the star, the rainfall, the aṭlāl: all are parts of a single cosmological language.
To search pre-Islamic poetry for a directly month-specific line such as "Shaʿbān arrived and my camels grew thirsty" is to ask the wrong question. The poet does not speak that language. He names the season through a star, a rainfall, a pasture, an abandoned campsite. These are not images chosen at random; they are concrete markers of the pre-Islamic Arab's calendar-reading system. The star-rain pairing he calls anwāʾ, the nightly shift of the lunar mansions he calls manāzil al-qamar, the cycle of sacred and profane months whose imprint the aṭlāl bears years later — all are parts of a single calendar.
This section examines the four pilot cases in which the pre-Islamic poetic canon offers direct testimony; three from the Muʿallaqāt canon and one from the structural analysis of the qaṣīda. Each shows, in a concrete text, how the poetic evidence is interwoven with the calendar-ritual system. The work of Suzanne and Jaroslav Stetkevych (1993), Daniel M. Varisco's anwāʾ research (1989-1994), and Ibn Qutayba's Kitāb al-Anwāʾ (mid-9th century CE; Hyderabad 1956) all support this reading.
In short: the poet does not name the month, because the star and the rainfall are already the month itself. Poetry carries the calendar; the calendar lives in poetry. This section unfolds that weave.
The opening nine verses of Labīd b. Rabīʿa's Muʿallaqa are the most powerful expression of pre-Islamic poetry's calendrical consciousness. When the poet sees the effaced campsites in the valley of Minā, he counts the years that have passed over them, but he counts them not as an ordinary unit of time but as the cycle of sacred and profane months. This is the direct poetic evidence of the pre-Islamic Arab's calendar consciousness.
"These are dwelling places; since the departure of those who lived in them, many long years have rolled by, full with the proper reckoning of profane and sacred months."
Labīd b. Rabīʿa al-ʿĀmirī (d. ca. 661 CE) · from William Wright's English translation (1961, Ursula Schedler edition)
The Arabic phrase ḥalāluhā wa-ḥarāmuhā ("its profane and sacred") in the original verse is an unambiguous calendrical reference. The poet measures the years that have passed not in ordinary days but in cycles of sacred-and-profane months. A year is the sum of twelve months following one another, from the sacred status of Muḥarram to the profane status of Shaʿbān, and the aṭlāl is the place over which this cycle has rolled many times.
Context: This verse stands at the heart of the Muʿallaqa's opening sequence (vv. 1-9). First the campsites have been effaced (vv. 1-2), then the years are counted by the sacred-profane cycle (v. 3), then the rains of the spring constellations come (v. 4), then spring revives plants and animals (vv. 6-7). The sequence calendar, rain, fertility, renewal is the full expression of the ancient Near Eastern seasonal-ritual pattern.
The technical name for the pre-Islamic Arab's reading of the sky is anwāʾ. Each of the twenty-eight mansions has a conjunction period with the Sun that is linked to particular rains; every rain carries its own star. This knowledge is not a technical calendar but a directly poetic language. When the poet says "The spring constellations gave their rain," he names a specific astronomical cycle.
"They were granted the rains of the spring constellations; the water of the thundering clouds fell on them in downpour and in drizzle."
Labīd b. Rabīʿa · Muʿallaqa, v. 4 · Wright's translation
The phrase marābīʿ al-nujūm (مَرابيعَ النُّجومِ) translates not as plain "spring stars" but as "star groups that bring the rains of spring." In the anwāʾ literature (Ibn Qutayba, Kitāb al-Anwāʾ fī Mawāsim al-ʿArab, Hyderabad 1956) these star groups are listed systematically: al-Dabarān, al-Haqʿa, al-Hanʿa, al-Dhirāʿ. In a single line of verse, Labīd states the title page of an astronomical calendar.
Labīd's next verses (vv. 5-9) work out the consequences of this rain: the cloud of the night, the cloud of the morning, the cloud of the evening follow one another; wild rocket sprouts; the gazelle and the ostrich bring forth their young; antelopes rest their fawns; the flood reopens the traces of the campsite. These nine verses are the lyric phenomenology of the anwāʾ system; the sequence star, rain, fertility, renewed dwelling.
An important distinction: This verse does not say "Rabīʿ al-Awwal," yet what it says is exactly what Rabīʿ al-Awwal is. The poet states not the name of the month but the astronomical content of the month.
The pre-Islamic poet stamps the time of an event not with an ordinary hour or the name of a day, but with the position of a star in the sky. The most frequent reference is the Pleiades (الثُّرَيَّا, al-Thurayyā) and their heliacal rising. The Muʿallaqa of Imruʾ al-Qays contains one of the best-known uses of this device.
"I slipped past my enemies when the Pleiades appeared in the sky, like the parts of an ornate sash falling sideways, with the gaps in it worked with pearls and gems."
Imruʾ al-Qays al-Kindī (d. ca. 540 CE) · Muʿallaqa, Pleiades verse · compiled from the translations of William Jones and Sir Charles Lyall
The Pleiades' first appearance on the horizon just before dawn (heliacal rising) stamps, in pre-Islamic observation, a particular season (early autumn) and a particular hour of the night. With this verse Imruʾ al-Qays does not say "at that time"; he says "the Pleiades had risen at that moment." He fixes the moment of the event with an astronomical clock.
In the same Muʿallaqa Imruʾ al-Qays also paints his night with the stars: "What a night it was, with you, the stars as if bound to Mount Yadhbul by firm ropes, the Pleiades as if drawn from the rock to a barn by linen strings." The endless stretching of the night, the stars seeming not to move; this image of an endless night is the poetic expression of a technical culture in which the wakeful observer tracked the motion of the stars.
Comparison: In ancient Greece, Hesiod in Erga kai Hēmerai uses exactly the same technique: he tells the farmer when to plough by "when the Pleiades set." The pre-Islamic star-calendar language is one branch of the shared astronomical culture of the Mediterranean basin.
The last twelve verses of Imruʾ al-Qays' Muʿallaqa are entirely a description of rain and storm. This is the passage that even the classical Arabic commentators set apart as "the most marvellous section of the Muʿallaqa." The poet begins from the sky; he likens the lightning to a monk's lamp; he names, one by one, the mountains and valleys onto which the rain falls.
"O friend, do you see the lightning? Let me show you its flashing: like the gleam of two hands among piled, crowned clouds."
Imruʾ al-Qays · Muʿallaqa, storm section, opening · Suheil Laher's translation
After this opening the poet names eleven different places onto which the rain falls: ʿUdhayb, Dārij, Yadhbul, Sitār, Qaṭan, Quṭayfa, Taymāʾ, Thabīr, Mujaymir, al-Ghabīṭ, the Wādī Jiwāʾ. These place names are not chosen at random; they are the real geographical map of Najd and the Hejaz. The poet follows the rain; the direction of the cloud, its speed, the height it covers, the valley in which it forms a river — all are observed and measured.
This list is the instantaneous geographical map of a single storm. As the classical commentators warn, "Sitār, Yadhbul, and Qaṭan cannot be seen from a single vantage point"; the poet stages this with the wide imaginative reach of poetry. Yet each name is a real place, and the list reflects the real seasonal geography of an actual tribe. The rain poem is the dramatic poetic narration of anwāʾ knowledge.
Conclusion: This closing of the Muʿallaqa is the expression of the principle that it is not "the poet who observes the calendar" but "the calendar that speaks the poet." The rain names itself; the poet is only its scribe.
The structure of the poem is the map of a seasonal cycle
In The Mute Immortals Speak: Pre-Islamic Poetry and the Poetics of Ritual (Cornell, 1993), Suzanne Pinckney Stetkevych argues that the three principal sections of the pre-Islamic qaṣīda (nasīb, raḥīl, fakhr) correspond to the three stages of the anthropologist Arnold van Gennep's rite of passage. On this reading, pre-Islamic poetry is, in its form, a ritual structure, and that structure is directly a symbolic map of the seasonal cycle.
Stetkevych's thesis is this: when the pre-Islamic poet composes his qaṣīda, he does not only narrate events; he performs the symbolic architecture of a rite of passage. The aṭlāl (drought and death), the raḥīl (the threshold wandering), the fakhr (the coming of rain and the renewal of life). The poetic record of the seasonal cycle that runs through the year is the qaṣīda form itself.
In her analysis of Imruʾ al-Qays' Muʿallaqa (chapter 7), Stetkevych also adds Theodor Gaster's "seasonal pattern" myth-ritual paradigm. According to this paradigm, the basic recurring structure of ancient Near Eastern myth and ritual is pollution, purification, rebirth. The final storm scene of the Muʿallaqa is exactly the poetic expression of this rebirth: the rain comes, the polluted desert is purified, fertility returns, the hero becomes potent.
In The Zephyrs of Najd (Chicago, 1993), Jaroslav Stetkevych defines the nasīb as "the places of lost happiness" and shows the structural parallel between the aṭlāl motif and the Arcadia image of European pastoral poetry. This reading situates pre-Islamic poetry not as a local Arab phenomenon but as one branch of the shared pastoral-calendrical poetic tradition of the Mediterranean basin; the season-ritual-poem triangle is a reflection of a universal cosmological language.
Another group of scholars (a thesis from Najah University in Palestine; F. A. S. Alshormani in Umm al-Qura Journal, 2024, "Rituals of the First Poem") argues that the aṭlāl motif is connected to an older Inanna/Ishtar fertility ritual pattern. On this reading, the poet's weeping at the abandoned campsite is the form in which the Sumero-Akkadian motif of the drying of nature after the goddess's departure has been transmitted into Arabic poetry; a talbiyāt (invocation) structure that waits for the rain and calls back the goddess. This view is more contested, but the question of the aṭlāl-rain axis extending back into myth-ritual roots remains an active discussion in the academic literature.
Conclusion: The pre-Islamic qaṣīda is a single utterance of the "poet-calendar-ritual" triangle. The verse is a moment, the qaṣīda a cycle, the canon of qaṣīdas a cosmological language. The entire tool is the concrete ground of this reading.

About the pre-Islamic Arab calendar
The Manāzil al-qamar are the twenty-eight stations through which the Moon passes in the course of its sidereal cycle of approximately 27.32 days, each station corresponding to a recognisable star or asterism along the ecliptic. The system, attested in pre-Islamic poetry and codified in later Arabic astronomical works such as al-Marzūqī's Kitāb al-Azmina, divides the year into a fixed cycle of stellar risings and settings used for navigation, agriculture, and meteorological forecasting (anwāʾ). The twenty-eight mansions are paralleled in Indian (nakṣatra) and Chinese (xiu) astronomies, and their relationship is still debated.
The pre-Islamic Arabian peninsula hosted a network of major seasonal fairs that combined commerce, poetry, arbitration, and worship. ʿUkāẓ, held near Ṭāʾif during the sacred month of Dhū al-Qaʿdah, was the most famous and is associated with the celebrated poetic contests in which the Muʿallaqāt are said to have been recited; Majannah followed at the boundary of the haram, and Dhū al-Majāz preceded the pilgrimage proper. These fairs structured the annual social and economic life of the peninsula and were protected by the four sacred months during which warfare was suspended.
Nasīʾ - literally "postponement" - was the practice of intercalating an additional month into the twelve-month lunar year, or shifting one of the four sacred months, in order to keep the pilgrimage and the fairs aligned with a particular agricultural or commercial season. The practice was administered by a specialised tribal authority known as the Qalāmis of the Banū Kināna, and is explicitly described in al-Bīrūnī's Āthār al-Bāqiya and in the early Arabic chronicles. It was abolished in 10 AH (632 CE) by the Qurʾanic verse 9:37, which fixed the lunar year at twelve months and severed the calendar from the seasons.
The seven Muʿallaqāt - the great pre-Islamic odes attributed to Imruʾ al-Qays, Ṭarafa, Zuhayr, Labīd, ʿAntara, ʿAmr b. Kulthūm, and al-Ḥārith b. Ḥilliza - are rich in references to the heliacal risings, settings, and movements of named stars, particularly Suhayl (Canopus), al-Thurayyā (the Pleiades), and the manāzil. These references function both as precise temporal markers - locating the events of the poem within a specific season - and as poetic metaphors for separation, distance, and longing. Studies by Ibrahim al-Hawi, Renate Jacobi, and Suzanne Stetkevych analyse these stellar tropes in detail.
The anwāʾ (sing. nawʾ) are the calendrical units formed by the simultaneous heliacal setting of a lunar mansion in the west and the heliacal rising of its opposing mansion in the east, traditionally believed to bring specific weather phenomena - rain, wind, heat, or cold. The pre-Islamic Arabs used a fixed cycle of twenty-eight anwāʾ over the year to predict rainfall and to time agricultural operations. The corpus is preserved in works such as Ibn Qutaybah's Kitāb al-Anwāʾ and Abū Ḥanīfa al-Dīnawarī's Kitāb al-Nabāt, which together constitute one of the richest non-religious literatures of early Islamic Arabia.
Direct primary evidence is rare because the pre-Islamic Arabs left a limited epigraphic record relative to neighbouring Sabaean, Nabataean, and Lihyanite traditions. The most substantial sources are later Arabic compilations: al-Bīrūnī's Āthār al-Bāqiya ʿan al-Qurūn al-Khāliya (eleventh century CE), Ibn Qutaybah's Kitāb al-Anwāʾ, al-Marzūqī's Kitāb al-Azmina wa-l-Amkina, and the encyclopaedic Nihāyat al-Arab of al-Nuwayrī. To these may be added the genealogical and prosographical works (Kitāb al-Aghānī, Sīra), as well as inscriptions in Old North Arabian (Safaitic, Thamudic, Lihyanite) which preserve month names and seasonal vocabulary.
