Byzantine calendar

The Byzantine calendar, also called the Roman calendar, the Creation Era of Constantinople or the Era of the World (Ancient Greek: Ἔτη Γενέσεως Κόσμου κατὰ Ῥωμαίους, also Ἔτος Κτίσεως Κόσμου or Ἔτος Κόσμου, abbreviated as ε.Κ.; literal translation of Ancient Greek Roman year since the creation of the universe), was the calendar used by the Eastern Orthodox Church from c. 691 to 1728 in the Ecumenical Patriarchate. It was also the official calendar of the Byzantine Empire from 988 to 1453 and of Kievan Rus' and Russia from c. 988 to 1700. This calendar was used also in other areas of the Byzantine commonwealth such as in Serbia, where it is found in old Serbian legal documents such as Dušan's Code, thus being referred to as the Serbian Calendar as well. Since Byzantine is a historiographical term, the original name uses the adjective "Roman" as it was what the Eastern Roman Empire continued calling itself.

The calendar was based on the Julian calendar, except that the year started on 1 September and the year number used an Anno Mundi epoch derived from the Septuagint version of the Bible. It placed the date of creation at 5509 years before the incarnation of Jesus, and was characterized by a certain tendency that had already been a tradition among Jews and early Christians to number the years from the calculated foundation of the world (Latin: Annus Mundi or Ab Origine Mundi— "AM"). Its Year One, marking the assumed date of creation, was September 1, 5509 BC, to August 31, 5508 BC. This would make the current year (AD 2023) 7532 (7531 before September 1; and 7532 after September 1).


Creation of Adam and Eve (Russian icon, 18th c.)

The first appearance of the term is in the treatise of a monk and priest, Georgios (AD 638–39), who mentions all the main variants of the "World Era" in his work. Georgios argues that the main advantage of the World era is the common starting point of the astronomical lunar and solar cycles, and of the cycle of indictions, the usual dating system in Byzantium since the 6th century. He also regarded it as the most convenient for the Easter computus. Complex calculations of the 19-year lunar and 28-year solar cycles within this world era allowed scholars to discover the cosmic significance of certain historical dates, such as the birth or the crucifixion of Jesus.

This date underwent minor revisions before being finalized in the mid-7th century, although its precursors were developed c. AD 412. By the second half of the 7th century, the Creation Era was known in Western Europe, at least in Great Britain. By the late 10th century (around AD 988), when the era appears in use on official government records, a unified system was widely recognized across the Eastern Roman world.

The era was ultimately calculated as starting on September 1, and Jesus was thought to have been born in the year 5509 since the creation of the world. Historical time was thus calculated from the creation, and not from Christ's birth as it was in the west after the Anno Domini system adopted between the 6th and 9th centuries. The eastern Church avoided the use of the Anno Domini system of Dionysius Exiguus, since the date of Christ's birth was debated in Constantinople as late as the 14th century.

The Byzantine calendar was identical to the Julian calendar except that:

The leap day of the Byzantine calendar was obtained in an identical manner to the bissextile day of the original Roman version of the Julian calendar, by doubling the sixth day before the calends of March, i.e., by doubling 24 February.

The Byzantine World Era was gradually replaced in the Eastern Orthodox Church by the Christian Era (Anno Domini), which was utilized initially by Patriarch Theophanes I Karykes in 1597, afterwards by Patriarch Cyril Lucaris in 1626, and then formally established by the Church in 1728. Meanwhile, as Russia received Orthodox Christianity from Byzantium, she inherited the Orthodox calendar based on the Byzantine Era (translated into Slavonic). After the collapse of the Byzantine Empire in 1453, the era continued to be used by Russia, which witnessed millennialist movements in Moscow in AD 1492 (7000 AM). It was only in AD 1700 that the Byzantine calendar in Russia was changed to the Julian calendar by Peter the Great. It still forms the basis of traditional Orthodox calendars up to today. September AD 2000 began the year 7509 AM.

The age of the world

God as architect of the world (frontispiece of Bible moralisée, c. 1220–1230)

The earliest extant Christian writings on the age of the world according to the biblical chronology are by Theophilus (AD 115–181) in his apologetic work To Autolycus, and by Julius Africanus (AD 200–245) in his Five Books of Chronology. Both of these early Christian writers, following the Septuagint version of the Old Testament, determined the age of the world to have been about 5,530 years at the birth of Christ.

Ben Zion Wacholder points out that the writings of the Church Fathers on this subject are of vital significance (even though he disagrees with their chronological system based on the authenticity of the Septuagint, as compared to that of the Masoretic Text), in that through the Christian chronographers a window to the earlier Hellenistic biblical chronographers is preserved:

An immense intellectual effort was expended during the Hellenistic period by both Jews and pagans to date creation, the flood, exodus, building of the Temple... In the course of their studies, men such as Tatian of Antioch (flourished in 180), Clement of Alexandria (died before 215), Hippolytus of Rome (died in 235), Julius Africanus of Jerusalem (died after 240), Eusebius of Caesarea in Palestine (260–340), and Pseudo-Justin frequently quoted their predecessors, the Graeco-Jewish biblical chronographers of the Hellenistic period, thereby allowing discernment of more distant scholarship.

The Hellenistic Jewish writer Demetrius the Chronographer (flourishing 221–204 BC) wrote On the Kings of Judea which dealt with biblical exegesis, mainly chronology; he computed the date of the flood and the birth of Abraham exactly as in the Septuagint, and first established the Annus Adami (Era of Adam), the antecedent of the Hebrew World Era, and of the Alexandrian and Byzantine Creation Eras.

Alexandrian Era

The Alexandrian Era (Greek: Κόσμου ἔτη κατ’ Ἀλεξανδρεῖς, Kósmou étē kat'Alexandreîs) developed in AD 412, was the precursor to the Byzantine Era. After the initial attempts by Hippolytus, Clement of Alexandria and others, the Alexandrian computation of the date of creation was worked out to be 25 March 5493 BC.

The Alexandrine monk Panodorus reckoned 5904 years from Adam to the year AD 412. His years began with August 29, corresponding to the First of Thoth, the Egyptian new year. Annianos of Alexandria however, preferred the Annunciation style[clarification needed] as New Year's Day, 25 March, and shifted the Panodorus era by about six months, to begin on 25 March. This created the Alexandrian Era, whose first day was the first day of the proleptic Alexandrian civil year in progress, 29 August 5493 BC, with the ecclesiastical year beginning on 25 March 5493 BC.

This system presents in a masterly sort of way the mystical coincidence of the three main dates of the world's history: the beginning of Creation, the incarnation, and the Resurrection of Jesus Christ. All these events happened, according to the Alexandrian chronology, on 25 March; furthermore, the first two events were separated by the period of exactly 5500 years; the first and the third one occurred on Sunday — the sacred day of the beginning of the Creation and its renovation through Christ.

Dionysius of Alexandria had earlier emphatically quoted mystical justifications for the choice of March 25 as the start of the year:

March 25 was considered to be the anniversary of Creation itself. It was the first day of the year in the medieval Julian calendar and the nominal vernal equinox (it had been the actual equinox at the time when the Julian calendar was originally designed). Considering that Christ was conceived at that date turned March 25 into the Feast of the Annunciation which had to be followed, nine months later, by the celebration of the birth of Christ, Christmas, on December 25.

The Alexandrian Era of March 25, 5493 BC was adopted by church fathers such as Maximus the Confessor and Theophanes the Confessor, as well as chroniclers such as George Syncellus. Its striking mysticism made it popular in Byzantium, especially in monastic circles. However this masterpiece of Christian symbolism had two serious weak points: historical inaccuracy surrounding the date of the resurrection of Jesus as determined by its Easter computus, and its contradiction to the chronology of the Gospel of St John regarding the date of the crucifixion of Jesus on Friday after the Passover.

Chronicon Paschale, Venetian edition of 1729

Chronicon Paschale

A new variant of the World Era was suggested in the Chronicon Paschale, a valuable Byzantine universal chronicle of the world, composed about the year 630 AD by some representative of the Antiochian scholarly tradition. It had for its basis a chronological list of events extending from the creation of Adam to the year AD 627. The chronology of the writer is based on the figures of the Bible and begins with 21 March, 5507.

For its influence on Greek Christian chronology, and also because of its wide scope, the Chronicon Paschale takes its place beside Eusebius, and the chronicle of the monk Georgius Syncellus which was so important in the Middle Ages; but in respect of form it is inferior to these works.

By the late 10th century, the Byzantine Era, which had become fixed at September 1 5509 BC since at least the mid-7th century (differing by 16 years from the Alexandrian date, and 2 years from the Chronicon Paschale), had become the widely accepted calendar of choice par excellence for Chalcedonian Orthodoxy.

Accounts in Church Fathers

John Chrysostom says in his Homily "On the Cross and the Thief", that Christ "opened for us today Paradise, which had remained closed for some 5000 years."

Isaac the Syrian writes in a Homily that before Christ "for five thousand years five hundred and some years God left Adam (i.e. man) to labor on the earth."

Augustine of Hippo writes in the City of God (written AD 413–426):

"Let us omit the conjectures of men who know not what they say when they speak of the nature and origin of the human race...They are deceived by those highly mendacious documents which profess to give the history of many thousands of years, though reckoning by the sacred writings we find that not 6,000 years have passed. (City of God 12:10)."

Augustine goes on to say that the ancient Greek chronology "does not exceed the true account of the duration of the world as it is given in our documents (i.e. the Scriptures), which are truly sacred."

Hippolytus of Rome (c. 170–235) maintained on Scriptural grounds that Jesus's birth took place in 5500 AM, and held that the birth of Christ took place on a passover day, deducing that its month-date was 25 March (see Alexandrian Era). He gave the following intervals:

"...from Adam to the flood 2242 years, thence to Abraham 1141 years, thence to the Exodus 430 years, thence to the passover of Joshua 41 years, thence to the passover of Hezekiah 864 years, thence to the passover of Josiah 114 years, thence to the passover of Ezra 107 years, and thence to the birth of Christ 563 years."

In his Commentary on Daniel, one of his earlier writings, he proceeds to set out additional reasons for accepting the date of 5500 AM:

"First he quotes Exod. xxv. 10f. and pointing out that the length, breadth and height of the ark of the covenant amount in all to 5½ cubits, says that these symbolize the 5,500 years from Adam at the end of which the Saviour was born. He then quotes from Jn. xix. 14 ' it was about the sixth hour ' and, understanding by that 5½ hours, takes each hour to correspond to a thousand years of the world's life..."

Around AD 202 Hippolytus held that Jesus was born in the 42nd year of the reign of Augustus and that he was born in 5500AM. In his Commentary on Daniel he did not need to establish the precise year of Jesus's birth; he is not concerned about the day of the week, the month-date, or even the year; it was sufficient for his purpose to show that Christ was born in the days of Augustus in 5500 AM.

Accounts in Byzantine authors

From Justinian's decree in AD 537 that all dates must include the Indiction, the unification of the theological date of creation (as yet unfinalized) with the administrative system of Indiction cycles became commonly referred to amongst Byzantine authors, to whom the indiction was the standard measurement of time.

In official documents

In the year AD 691, we find the Creation Era in the Acts of the Quinisext Council:

... as of the fifteenth day of the month of January last past, in the last fourth Indiction, in the year six thousand one hundred and ninety"

We find the era also in the dating of the so-called Letter of three Patriarchs to the emperor Theophilos (April, indiction 14, 6344 = AD 836).

By the 10th century the Byzantine Era is found in the Novellas of AD 947, 962, 964, and most surely of the year AD 988, all dated in this way, as well as the Act of Patriarch Nicholaos II Chrysobergos in AD 987.

John Skylitzes' (c. 1081–1118) major work is the Synopsis of Histories, which covers the reigns of the Byzantine emperors from the death of Nicephorus I in 811 to the deposition of Michael IV in 1057; it continues the chronicle of Theophanes the Confessor. Quoting from him as an example of the common Byzantine dating method, he refers to emperor Basil, writing that:

In the year 6508 [1000], in the thirteenth indiction, the emperor sent a great force against the Bulgarian fortified positions (kastra) on the far side of the Balkan (Haimos) mountains,..."

Niketas Choniates (c. 1155–1215), sometimes called Acominatus, was a Byzantine Greek historian. His chief work is his History, in twenty-one books, of the period from 1118 to 1207. Again, an example of the dating method can be seen as he refers to the fall of Constantinople to the fourth crusade as follows:

The queen of cities fell to the Latins on the twelfth day of the month of April of the seventh indiction in the year 6712 [1204]."

The historian Doukas, writing c. AD 1460, makes a detailed account for the Creation Era. Although unrefined in style, the history of Doukas is both judicious and trustworthy, and it is the most valuable source for the closing years of the Byzantine empire.

From Adam, the first man created by God, to Noah, at whose time the flood took place, there were ten generations. The first, which was from God, was that of Adam. The second, after 230 years, was that of Seth begotten of Adam. The third, 205 years after Seth, was that of Enos begotten of Seth. The fourth, 190 years after Enos, was that of Kainan begotten of Enos. The fifth, 170 years after Kainan, was that of Mahaleel begotten of Kainan. The sixth, 165 years after Mahaleel, was that of Jared begotten of Mahaleel. The seventh, 162 years after Jared, was that of Enoch begotten of Jared. The eighth, 165 years after Enoch, was that of Methuselah begotten of Enoch. The ninth, 167 years after Methuselah, was that of Lamech begotten of Methuselah. The tenth, 188 years after Lamech, was that of Noah. Noah was 600 years old when the flood of water came upon the earth. Thus 2242 years may be counted from Adam to the flood.

There are also ten generations from the flood to Abraham numbering 1121 years. Abraham was seventy-five years old when he moved to the land of Canaan from Mesopotamia, and having resided there twenty-five years he begat Isaac. Isaac begat two sons, Esau and Jacob. When Jacob was 130 years old he went to Egypt with his twelve sons and grandchildren, seventy-five in number. And Abraham with his offspring dwelt in the land of Canaan 433 years, and having multiplied they numbered twelve tribes; a multitude of 600,000 were reckoned from the twelve sons of Jacob whose names are as follows: Ruben, Symeon, Levi, Judah, Issachar, Zebulun, Naphtali, Gad, Asher, Dan, Joseph, and Benjamin.

The descendants of Levi were Moses and Aaron; the latter was the first of the priesthood while Moses was appointed to govern. In the eightieth year of his life, he walked through the Red Sea and led his people out of Egypt. This Moses flourished in the time of Inachos [son of Oceanus and King of Argos] who was the first [Greek] king to reign. Thus the Jews are more ancient than the Greeks.

Remaining in the wilderness forty years they were governed for twenty-five years by Joshua, son of Nun, and by the Judges for 454 years to the reign of Saul, the first king installed by them. During the first year of his reign, the great David was born. Thus from Abraham to David fourteen generations are numbered for a total of 1024 years. From David to the deportation to Babylon [586 BC] there are fourteen generations totaling 609 years. From the Babylonian Captivity to Christ there are fourteen generations totaling 504 years.

By the sequence of Numbers we calculate the number of 5,500 years from the time of the first Adam to Christ.

Byzantine mindset

Literal creation days

Even the most mystical Fathers such as St. Isaac the Syrian accepted without question the common understanding of the Church that the world was created "more or less" in 5,500 BC. As Fr. Seraphim Rose points out:

"The Holy Fathers (probably unanimously) certainly have no doubt that the chronology of the Old Testament, from Adam onwards, is to be accepted "literally." They did not have the fundamentalist's over-concern for chronological precision, but even the most mystical Fathers (St. Isaac the Syrian, St. Gregory Palamas, etc.) were quite certain that Adam lived literally some 900 years, that there were some 5,500 years ("more or less") between the creation and the Birth of Christ."

For early Christians, the creation of the world was neither a matter of dogma nor a cosmological problem. As part of a history centered on Man, it was a divine act whose reality was beyond any doubt.

Hours of the liturgical day

In the Byzantine period, the day was divided into two 12-hour cycles fixed by the rising and setting of the sun.

"Following Roman custom, the Byzantines began their calendrical day (nychthemeron) at midnight with the first hour of day (hemera) coming at dawn. The third hour marked midmorning, the sixth hour noon, and the ninth hour midafternoon. Evening (hespera) began at the 11th hour, and with sunset came the first hour of night (apodeipnon). The interval between sunset and sunrise (nyx) was similarly divided into 12 hours as well as the traditional "watches" (vigiliae) of Roman times."

Days of the liturgical week

Marcus Rautman points out that the seven-day week was known throughout the ancient world. The Roman Calendar had assigned one of the planetary deities to each day of the week. The Byzantines naturally avoided using these Latin names with their pagan echoes. They began their week with the "Lord's Day" (Kyriake), followed by an orderly succession of numbered days: Deutera ("2nd"), Trite ("3rd"), Tetarte ("4th"), and Pempte ("5th"), a day of "preparation" (Paraskeve), and finally Sabatton.

Each day was devoted to remembering one event of the life of Christ or the Theotokos or several martyrs or saints, whose observed feast days gradually eclipsed traditional festivals. Kyriake was seen as the day of resurrection of Christ and as both the first and eighth day of the week, in the same way that Christ was the alpha and omega of the cosmos, existing both before and after time. The second day of the week recognized angels, "the secondary luminaries as the first reflections of the primal outpouring of light", just as the sun and the moon had been observed during the Roman week. John the Baptist, the forerunner (Prodromos) of Christ, was honored on the third day. Both the second and third days were viewed as occasions for penitence. The fourth and sixth days were dedicated to the Cross. The fourth day to the Theotokos and her mourning of the loss of her son and the sixth day (the Paraskeue) as the day of the Crucifixion of the Lord, with holy songs sung and fasting in remembrance of these events. St. Nicholas was honored on the fifth day of the week, while the Sabatton day was set aside for the saints and all the deceased faithful. This order is still in use in the Orthodox Church and the Eastern Catholic Churches.

A special arrangement of the way in which the hymns were sung was set for each day of the eight-week cycle, the "Octoechos (liturgy)". This cycle begins on the first Sunday after Easter ("Thomas-Sunday") and contains the texts whose content represents the meaning of the days of the week. The hymns sung on these eight weeks were performed with the use of eight different modes also called Octoechoi.

Historical perspective and cognitive framework

Regarding questions about the scientific accuracy of the Genesis account of creation, and about various viewpoints concerning evolution, the Eastern Orthodox Church has not dogmatized any particular view. What is dogmatically proclaimed is that the One Triune God created everything that exists, and that man was created in a unique way and is alone made in the image and likeness of God (Gn 1:26,27).
The opening words of the Nicene Creed, the central doctrinal statement of Christianity, affirms that the One True God is the source of everything that exists, both physical and spiritual, both animate and inanimate: "We believe in one God, the Father Almighty, Maker of Heaven and Earth, and of all things visible and invisible." In addition, our regeneration in Christ and the resurrection of the dead are both often called the "New Creation" (2 Cor 5:17; Rev 21:1).
  • According to Fr. Stanley Harakas, the Bible's description of creation is not a "scientific account". It is not read for scientific knowledge but for spiritual truth and divine revelation. The physical-scientific side of the origins of mankind, though important, is really quite secondary in significance to the Church's message. The central image of Adam as God's image and likeness, who also represents fallen and sinful humanity, and the new Adam, Jesus Christ, who is the "beginning", the first-born of the dead (Colossians 1:18) and the "first-fruits" of those who were dead, and are now alive (1 Corinthians 15:20–23), is what is really important.
  • Protopresbyter Dr. Doru Costache affirms in "The Orthodox Doctrine of Creation in the Age of Science" (2019), that Orthodox Christianity has never issued a dogma of creation that establishes in normative terms its relevant convictions, even though it does possess a strong sense of the cosmos, developing a theology of the world. While not specifically discussing the chronology of the Byzantine Calendar as such, he explains that the Orthodox doctrine of creation is largely compatible with the contemporary scientific representation of reality, also suggesting that the Christian doctrine of creation should preserve its capacity to be redrafted when the cultural environment changes. He states that modern creationism has originated in milieus that are foreign to the Orthodox worldview, and there is no record of a wholesale rejection of culture in the patristic tradition. Rather, from the outset of its historical emergence, Orthodox theology has traditionally interacted with the available sciences and the cultural frameworks of the past. The ongoing contextualization, particularly in relation to scientific culture, remained the norm for most of the Byzantine era, which was a time of prodigious research, cultural cross pollination, and innovation. In contrast with contemporary creationism, which construes a recently made world, molded exclusively by God out of an inert matter deprived of natural energy and capacity for movement, the Orthodox theology of creation traditionally advocates a distinction between the divine acts of creation, and organization. He argues that the supernaturalist worldview of creationism was discarded indirectly by the Orthodox Church in the seventh century as monoenergism. Thus he aligns with the view of an expanding universe whose history began billions of years ago, a universe characterized by homogeneity, movement, change, and complexity.
  • Postdoctoral researcher Alexander V. Khramov (Ph.D.) examines the relationship between Christian faith and evolutionary theory in "Fitting Evolution into Christian Belief: An Eastern Orthodox Approach" (2017). In defining the basic cognitive framework by which we are to approach this subject, he begins by noting that those who have striven to reconcile one system with the other have usually resorted to theistic evolution (TE) almost without exception – the idea that God employed an evolutionary process to create the Universe and living things. However, if we look instead at the problem from the point of view of Greek patristic thought, we see a very different way of fitting evolution into Christian belief. By referring to the writings of the Church Fathers including Gregory of Nyssa and Gregory the Theologian, he states that what matters most is not the process of creation, but rather how the Church Fathers understood its result. The basic premise described is that God did not create humans in their present bodily condition; but rather prelapsarian human beings (i.e. before the Fall of man) had spiritual bodies and lived a kind of angelic life; humans entered the organismic life and entered 'time' itself only after the Fall, which happened before the beginning of the empirically known universe. Therefore it is entirely reasonable to suppose that evolution itself started in the fallen world; and Theistic evolutionists have no warrant to equate the earliest members of Homo sapiens with those humans who were created by God on the sixth day for life in paradise. The six days of creation and other events preceding the expulsion from Paradise simply lie beyond what science can discover. So "Moses's Book" possesses its own truth, independent of what scientists can say about the observable world. There can be no reason for conflict.
  • Professor Fr. Arsenius John Baptist Vuibert (S.S.), a 19th-century historian, observed that Biblical Chronologies are uncertain due to discrepancies in the figures in Genesis and other methodological factors, accounting for hundreds of different chronologies being assigned by historians. In the case of the Fathers of the Sixth Ecumenical Council, who assigned 5509 BC. as the date of the creation of man, he writes that it was in response to the emperor's wishes to fix an era or convenient starting point for historical computation. Therefore, it was a decision of mere historical convenience, not respecting either faith or morals, which are what is truly of intrinsic value in the Scriptures. Having made this disclaimer, he settles on the Benedictine Chronology of 4963 BC for the purposes of his history.
  • According to the ninth edition of the Encyclopædia Britannica, regarding the so-called Era of the Creation of the World, Alphonse Des Vignoles [fr] asserted in the preface to his Chronologie de l’Histoire Sainte (Chronology of Sacred History, Berlin 1738), that he collected upwards of two-hundred different calculations, the shortest of which reckons only 3483 years between the creation of the world and the commencement of the vulgar era and the longest 6984. The so-called era of the creation of the world is therefore a purely conventional and arbitrary epoch, for which the very nature of the case discussion is hopeless labour.
  • It may also be noted historically that while Byzantine officials and chroniclers were disconcerted by the ambiguities among the different dating and recording systems in the earlier centuries, these mattered little to most people who marked time by the orderly progression of agricultural seasons and church festivals, and by the regularity of holidays, weather cycles, and years that revealed the Divine order (Taxis) underlying the world.


As the Greek and Roman methods of computing time were connected with certain pagan rites and observances, Christians began at an early period to adopt the Hebrew practice of reckoning their years from the supposed period of the creation of the world.

Currently the two dominant dates for creation that exist using the biblical model are about 5500 BC and about 4000 BC. These are calculated from the genealogies in two versions of the Bible, with most of the difference arising from two versions of Genesis. The older dates of the Church Fathers in the Byzantine Era and in its precursor, the Alexandrian Era, are based on the Greek Septuagint. The later dates of the Ussher chronology and the Hebrew calendar are based on the Hebrew Masoretic Text.

The Fathers were well aware of the discrepancy of some hundreds of years between the Greek and Hebrew Old Testament chronology, and it did not bother them; they did not quibble over years or worry that the standard calendar was precise "to the very year"; it is sufficient that what is involved is beyond any doubt a matter of some few thousands of years, involving the lifetimes of specific men, and it can in no way be interpreted as millions of years or whole ages and races of men.

To this day, traditional Orthodox Christians will use the Byzantine calculation of the World Era in conjunction with the Anno Domini (AD) year. Both dates appear on Orthodox cornerstones, ecclesiastical calendars and formal documents. The ecclesiastical new year is still observed on September 1 (or on the Gregorian Calendar's September 14 for those churches which follow the Julian Calendar). September 2022 marked the beginning of the year 7531 of this era.
