Pre-Islamic Arab Calendar
Before Islam the Arabian Peninsula used a calendar that followed the Moon and the Sun together. In that period Ramaḍān still pointed to the scorching heat, Jumādā to the dried-up water and Rabīʿ to the spring pasture. 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. The primary source for this reconstruction is poetry.
Why This Reconstruction?
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. There is, however, an enormous archive that tells us how this calendar worked, which stars brought which rains and which season each month name carried, and that archive is pre-Islamic Arabic poetry. The Muʿallaqāt, the Mufaḍḍaliyyāt, the Dīwān al-Hudhaliyyīn and the Aṣmaʿiyyāt are its principal collections. Hundreds of poets wrote tens of thousands of verses, and those verses keep a record of the stars, the months, the rains and the storms.
When the poet says Jumādā he means dried-up water, when he says Rabīʿ he means pasture, and when he says Ramaḍān he means scorching heat. The pre-Islamic poet nevertheless 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 names the season instead through a star, a rainfall, a pasture or an abandoned campsite. Imruʾ al-Qays likens the Pleiades to the pearls on a woman's sash. Labīd has the rains of the spring constellations wash away the traces of the campsite. Abū Dhuʾayb uses al-Jabbār, that is Orion, as the orienting marker of the night hunt. These verses are not weaker testimony for failing to name a month. They are stronger, because they are first-hand documents that keep the calendar alive in its own imagistic language.
This tool rebuilds that system in the light of poetry. For the year you select it lists the twelve months in order. For each month you can read its etymology, its seasonal meaning, the verse fragments attributed to it where they survive, and the matching manāzil al-qamar (the twenty-eight lunar mansions) and anwāʾ (star-rain relations). The ashhur al-ḥurum, the four sacred months, are picked out in gold, since warfare and blood feud were suspended in them. The pilgrimage and fair cycle that runs from Dhū al-Qaʿda to Muḥarram is mapped as a single religious and economic season. The nasīʾ section sets two readings side by side: the classical Islamic astronomers who took the word as intercalation (al-Bīrūnī, Abū Maʿshar), and the modern orientalists who took it as the displacement of the sacred months (Mahmud Effendi, de Blois).
Modern scholarship, and above all the two landmark books that Suzanne and Jaroslav Stetkevych published in 1993, reads the pre-Islamic qaṣīda as a calendrical and ritual structure in its very form. On that reading the poet does not name a month because the qaṣīda itself, with its aṭlāl, raḥīl and 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 time stamp, and the geographical anwāʾ map of Imruʾ al-Qays' storm scene.
You will not find the cuneiform tablets of Babylon here, nor the stone walls of Egypt, the philosophical texts of Greece or the official records of Rome. In their place stands the elegy that Abū Dhuʾayb al-Hudhalī wrote for his sons. There is Imruʾ al-Qays' secret visit to his beloved, and there are the empty traces of tents that Labīd finds at Minā. Poetry is the language of the calendar here, and it forms the pre-Islamic Arabs' own system for recording the sky.
The Twelve Months
This is 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 of the months are ḥarām, and in them war and blood feud are taboo, while the fairs near the Kaʿba carry the economy of that inviolability. Click a month to see its etymology, its poetic record, the matching lunar mansions and the anwāʾ star-rain pairings.
The Pilgrimage Season and the Fair Cycle
The sacred status of Dhū al-Qaʿda, Dhū al-Ḥijja and Muḥarram rests on an economic logic as much as a religious one. For three months the fairs around the Kaʿba, at ʿUkāẓ, Majannah and Dhū al-Majāz, gather tribes from across the Arabian Peninsula. Blood feud is suspended, and trade, poetry, divination and marriage are all arranged during this season.
Manāzil al-Qamar · The Twenty-Eight Lunar Mansions
In its sidereal cycle the Moon lodges each night in a different constellation. There are twenty-eight such mansions, and in each of them the period of the Moon's conjunction with the Sun is linked to particular rains or winds. The system runs parallel to the Indian nakshatra and the Chinese xiu, and their shared origin is most likely Mesopotamian. In the pre-Islamic era it lived as the anwāʾ system. With Islam, astrological and mystical layers were added to it, among them Ibn ʿArabī's treatment in al-Futūḥāt.
The Anwāʾ Year Wheel · The Star-Rain Calendar
The anwāʾ system works like this. As one mansion sets in the west at dawn (suqūṭ), its raqīb, fourteen mansions away, rises heliacally in the east. The setting mansion is the holder of the nawʾ, and it "brings" the rain, wind or heat attached to it. In the classical count each nawʾ period lasts thirteen days. Only al-Jabha's lasts fourteen, and that is how Ibn Qutayba completes the year (27 x 13 + 14 = 365). The schedule below is computed for the year you selected above. Solar longitude comes from the Meeus series, the mansion boundaries are equal divisions starting from beta Arietis, and they are carried to the selected year by precession. The intervals therefore vary around 13 days with the Sun's elliptical speed. Since the classical anwāʾ rest on real observation of the stars, the dates are approximate.
The names of the rain periods come from the classical anwāʾ literature (Ibn Qutayba, Kitāb al-Anwāʾ; see also Varisco 1987 and 1991 in the bibliography). Their boundaries vary from source to source, and the position of al-dafaʾī varies most of all. Ibn Qutayba places it after the spring rains, while the lexicographical tradition places it at the end of winter, and the arrangement used here follows Varisco's reconstruction. The dates in the schedule are computed with the equal-division approximation for the mansions. In an equal division some indicator stars, Aldebaran among them, fall into the neighbouring segment, and real observation may shift by a few days according to the brightness of the star and the state of the horizon.
The Pre-Islamic Sky
These are the stars the poet invokes most often, and each of them carries its own season, its own image and its own rain. The same sky belongs to Babylon, to Greece and to India as well, and the same star is named with the same function in all three languages.
The Nasīʾ Debate
The Qurʾān (Tawba 36-37) strictly forbids nasīʾ, "postponement". The prohibition confirms that the practice was active in the pre-Islamic period. Scholars still disagree, however, about what that practice actually was, and two main interpretations hold the field.
Classical Interpretation · Intercalation
The pre-Islamic Arabs added a thirteenth month every two or three years, much as the Jewish calendar does. The addition anchored the calendar to the seasons, so that Ramaḍān stayed in summer and Rabīʿ in spring. Nasīʾ was the name of that intercalation.
In al-Āthār al-bāqiya al-Bīrūnī reports that an official of the Banū Kināna tribe, called the qalammas or nāsiʾ, announced the intercalation during the pilgrimage season. Scholars have proposed either a nineteen-year cycle with seven intercalations, on the Metonic pattern, or a twelve-year cycle with four.
The strongest argument for this interpretation is poetic. In the last century before Islam the month names were used in active agreement with their seasonal meanings. A pure lunar calendar would invert the seasons over 33 years, and no such drift is visible in the poetry.
Modern Interpretation · Displacement of the Sacred Months
Nasīʾ was not an intercalation but the practice of shifting the position of the sacred months. When tribes wanted to pursue a blood feud, they pushed the Muḥarram of a given year onto Ṣafar, and in this way they manipulated which stretch of time counted as "forbidden". The same shift could also move the pilgrimage into a different season.
Evidence for this interpretation comes from an early Sabaean inscription in which the verb nsʾw carries the sense of "postponing a religious rite because of war". What is postponed there is an event, not a month.
If this view is correct, the Arab calendar was already purely lunar by the early years of Islam. The prohibition of nasīʾ then halted a social manipulation rather than reforming a calendar. This reading is hard to reconcile with the poetic evidence.
Under ʿUmar the Hijri years were standardised, with 1 AH beginning on 1 Muḥarram in 622 CE. The Hijri calendar is purely lunar and uses no nasīʾ. Ramaḍān can therefore fall in any season, and the original seasonal meaning of the month names survives today only as etymology.
Dahr · The Pre-Islamic Arab Conception of Fate
"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. Dahr is an invisible, impersonal and unquestionable force, the passing time that consumes everything. It resembles the Hellenistic heimarmene or the Roman fatum, but it lives without any astronomical technique behind it, as an intuitive and poetic faith in fate. The stars witness dahr and the rains set its seal. With the coming of Islam the role of dahr was redefined theologically, and a hadith, "Do not curse dahr, for God is dahr", bound the blind time of pre-Islamic poetry to the divine will. That is one of the critical points in the transition from poetry to religion. The perception of time here is cosmological rather than theological, since the stars and the seasons are the visible face of dahr and a human life is only a brief line in its record.
The Calendrical Structure of Poetry
Why does the pre-Islamic poet never name a month directly, when his whole poem carries a calendrical structure? The verse, the season, the star, the rainfall and the aṭlāl all belong to a single cosmological language.
To search pre-Islamic poetry for a 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 or an abandoned campsite. These images are not chosen at random, because each one is a concrete marker of the way the pre-Islamic Arab read his calendar. The star-rain pairing he calls anwāʾ, the nightly shift of the lunar mansions he calls manāzil al-qamar, and the cycle of sacred and profane months whose imprint the aṭlāl still bears years later all belong to one calendar.
This section examines the four pilot cases in which the pre-Islamic poetic canon offers direct testimony. Three of them come from the Muʿallaqāt and one from the structural analysis of the qaṣīda. Each shows in a concrete text how the poetic evidence interlocks with the calendar and its rituals. 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, and the calendar lives inside the poetry. This section unfolds that weave.
The opening nine verses of Labīd b. Rabīʿa's Muʿallaqa are the most powerful expression of the calendrical consciousness of pre-Islamic poetry. When the poet sees the effaced campsites in the valley of Minā, he counts the years that have passed over them. He counts them not in an ordinary unit of time but in the cycle of sacred and profane months, and that gives us direct poetic evidence of how the pre-Islamic Arab thought about time.
حِجَجٌ خَلَوْنَ حَلَالُها وَحَرَامُها
"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 in cycles of sacred and profane months rather than in ordinary days. 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 that 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 tied to particular rains, and every rain carries its own star. This body of knowledge reaches us not as a technical calendar but as a directly poetic language. When the poet says "The spring constellations gave their rain", he is naming a specific astronomical cycle.
وَدْقُ الرَّواعِدِ جَوْدُها فَرِهامُها
"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) does not translate as plain "spring stars" but as "star groups that bring the rains of spring". The anwāʾ literature lists those groups systematically, among them al-Dabarān, al-Haqʿa, al-Hanʿa and al-Dhirāʿ (Ibn Qutayba, Kitāb al-Anwāʾ fī Mawāsim al-ʿArab, Hyderabad 1956). In a single line of verse Labīd sets out the title page of an astronomical calendar.
Labīd's next verses (vv. 5-9) work out what this rain produces. The cloud of the night, the cloud of the morning and the cloud of the evening follow one another, wild rocket sprouts, the gazelle and the ostrich bring forth their young, antelopes rest their fawns, and the flood reopens the traces of the campsite. These nine verses give the lyric phenomenology of the anwāʾ system, running from star to rain to fertility and on to the dwelling renewed.
An important distinction: The verse does not say "Rabīʿ al-Awwal", yet what it describes is exactly what Rabīʿ al-Awwal is. The poet gives the astronomical content of the month instead of its name.
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.
تَعَرُّضَ أَثْنَاءِ الوِشاحِ المُفَصَّلِ
"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
In pre-Islamic observation the first appearance of the Pleiades on the horizon just before dawn, their heliacal rising, marks a particular season, early autumn, and a particular hour of the night. In this verse Imruʾ al-Qays does not say "at that time". He says "the Pleiades had risen at that moment", and so he fixes the event by an astronomical clock.
In the same Muʿallaqa Imruʾ al-Qays 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 night stretches out and the stars appear not to move. That image of an endless night comes out of a technical culture in which a 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 given over entirely to rain and storm. Even the classical Arabic commentators set this passage apart as "the most marvellous section of the Muʿallaqa". The poet begins from the sky, likens the lightning to a monk's lamp, and names one by one the mountains and valleys onto which the rain falls.
كَلَمْعِ اليَدَيْنِ في حَبِيٍّ مُكَلَّلِ
"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 and the Wādī Jiwāʾ. These names are not chosen at random, because together they form a real geographical map of Najd and the Hejaz. The poet follows the rain, and he observes and measures the direction of the cloud, its speed, the height it covers and the valley in which it turns into a river.
- The lightning is the gleam of two hands among crowned clouds, then like a monk's lamp filled with olive oil
- At Quṭayfa the rain lays low even the large trees
- On Mount Kanān the wild goats come down by every slope
- At Taymāʾ not a single palm tree stands, and only the stone-bound towers hold
- Mount Thabīr, covered with rain, resembles an old man in a striped robe
- By morning Mujaymir is encircled with foam, like the wheel of a spinning loom
- The al-Ghabīṭ plain wears a green mantle, like cloth spread out by a merchant
- At Jiwāʾ the whistling birds sing as if they had drunk spiced wine
This list is the instantaneous geographical map of a single storm. The classical commentators warn that "Sitār, Yadhbul and Qaṭan cannot be seen from a single vantage point", and the poet stages the scene with the wide imaginative reach that poetry allows. Each name is nonetheless a real place, and the list reflects the real seasonal geography of an actual tribe. The rain poem narrates anwāʾ knowledge in dramatic form.
Conclusion: This closing of the Muʿallaqa expresses a principle: it is not "the poet who observes the calendar" but "the calendar that speaks the poet". The rain names itself, and the poet only writes it down.
The Stetkevych Paradigm: The Qaṣīda Is Itself a Ritual
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 that the pre-Islamic poet does more than narrate events when he composes a qaṣīda. He performs the symbolic architecture of a rite of passage, moving from the aṭlāl of drought and death, through the threshold wandering of the raḥīl, to the fakhr in which the rain comes and life is renewed. The qaṣīda form is itself the poetic record of the seasonal cycle that runs through the year.
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. On his reading pre-Islamic poetry is not a local Arab phenomenon but one branch of the shared pastoral and calendrical poetic tradition of the Mediterranean basin, and the triangle of season, ritual and poem reflects a cosmological language found well beyond Arabia.
Another group of scholars connects the aṭlāl motif to an older Inanna and Ishtar fertility ritual pattern; see a thesis from Najah University in Palestine and F. A. S. Alshormani in Umm al-Qura Journal, 2024, "Rituals of the First Poem". On that reading the poet's weeping at the abandoned campsite is the form in which the Sumero-Akkadian motif of nature drying up after the goddess departs has passed into Arabic poetry, as a talbiyāt or invocation structure that waits for the rain and calls the goddess back. The view is more contested, but the question of whether the aṭlāl-rain axis reaches back to myth-ritual roots is still actively discussed in the scholarly literature.
Conclusion: The pre-Islamic qaṣīda speaks the triangle of poet, calendar and ritual in a single utterance. A verse holds a moment, a qaṣīda holds a cycle, and the canon of qaṣīdas holds a whole cosmological language. This tool sets out the concrete ground for that reading.
Pre-Islamic Poets
These are the poets at the top of the tradition: the seven of the Muʿallaqāt, the corpus of the Hudhayl tribe and the tribal poets around them. Each of them spoke his own season, his own star and his own rain.
