It was winter in the Boiling Isles, and Luz was acting odd.
For days now, she had been festooning the Owl House with red/green ribbons, cutting down trees and putting colorful orbs and light glyphs on their branches, singing saccharine songs about the joy of giving, hanging some type of obligate hemiparasitic herb over Hooty's door, and brewing some kind of horrifying substance that seemed to be composed of eggs, cream, and some sharp-smelling substance, possibly rum. The current inhabitants - Eda, King, and Amity- had been giving Luz a wide berth.
After Luz was discovered painting Hooty green, the inhabitants had decided it was time for an intervention.
"...Luz?"
Luz whipped around. "Amity, hey! How ya doin'! Paint? WhAt PaInt?"
Amity sighed. "Luz, as your girlfriend-"
Eda cut the young witch off. "Luz, you've been acting super weird lately, and we want to know why. Why?"
Luz took on her trademark Silly Grin™. "Ha! Don't act like you don't know! It's Christmas!"
"What?"
Eda's face took on a dim expression of recognition. "I think it's a human holiday."
Luz began to look shocked. "You mean to tell me that you don't know what Christmas is? Oh. Oh my."
A few minutes later, they were sitting in front of a chalkboard.
"Alright, time for a crash course!"

Christmas is an annual festival commemorating the birth of Jesus Christ, observed primarily on December 25 as a religious and cultural celebration among billions of people around the world. A feast central to the Christian liturgical year, it is preceded by the season of Advent or the Nativity Fast and initiates the season of Christmastide, which historically in the West lasts twelve days and culminates on Twelfth Night. Christmas Day is a public holiday in many countries, is celebrated religiously by a majority of Christians, as well as culturally by many non-Christians, and forms an integral part of the holiday season organized around it.
The traditional Christmas narrative, the Nativity of Jesus, delineated in the New Testament says that Jesus was born in Bethlehem, following messianic prophecies. When Joseph and Mary arrived in the city, the inn had no room and so they were offered a stable where the Christ Child was soon born, with angels proclaiming this news to shepherds who then spread the word.
Although the month and date of Jesus' birth are unknown, the church in the early fourth century fixed the date as December 25. This corresponds to the date of the winter solstice on the Roman calendar. It is exactly nine months after Annunciation on March 25, also the date of the spring equinox. Most Christians celebrate on December 25 in the Gregorian calendar, which has been adopted almost universally in the civil calendars used in countries throughout the world. However, part of the Eastern Christian Churches celebrates Christmas on December 25 of the older Julian calendar, which currently corresponds to January 7 in the Gregorian calendar. For Christians, believing that God came into the world in the form of man to atone for the sins of humanity, rather than knowing Jesus' exact birth date, is considered to be the primary purpose in celebrating Christmas.
The celebratory customs associated in various countries with Christmas have a mix of pre-Christian, Christian, and secular themes and origins. Popular modern customs of the holiday include gift-giving; completing an Advent calendar or Advent wreath; Christmas music and caroling; viewing a Nativity play; an exchange of Christmas cards; church services; a special meal; and the display of various Christmas decorations, including Christmas trees, Christmas lights, nativity scenes, garlands, wreaths, mistletoe, and holly. In addition, several closely related and often interchangeable figures, known as Santa Claus, Father Christmas, Saint Nicholas, and Christkind, are associated with bringing gifts to children during the Christmas season and have their own body of traditions and lore. Because gift-giving and many other aspects of the Christmas festival involve heightened economic activity, the holiday has become a significant event and a key sales period for retailers and businesses. Over the past few centuries, Christmas has had a steadily growing economic effect in many regions of the world.
Etymology
"Christmas" is a shortened form of "Christ's mass". The word is recorded as Crīstesmæsse in 1038 and Cristes-messe in 1131. Crīst (genitive Crīstes) is from Greek Khrīstos (Χριστός), a translation of Hebrew Māšîaḥ (מָשִׁיחַ), "Messiah", meaning "anointed"; and mæsse is from Latin missa, the celebration of the Eucharist.
The form Christenmas was also historically used but is now considered archaic and dialectal. The term derives from Middle English Cristenmasse, meaning "Christian mass". Xmas is an abbreviation of Christmas found particularly in print, based on the initial letter chi (Χ) in Greek Khrīstos (Χριστός), "Christ", though numerous style guides discourage its use. This abbreviation has precedent in Middle English Χρ̄es masse (where "Χρ̄" is an abbreviation for Χριστός).
Other names
In addition to "Christmas", the holiday has been known by various other names throughout its history. The Anglo-Saxons referred to the feast as "midwinter", or, more rarely, as Nātiuiteð (from Latin nātīvitās below). "Nativity", meaning "birth", is from Latin nātīvitās. In Old English, Gēola (Yule) referred to the period corresponding to December and January, which was eventually equated with Christian Christmas. "Noel" (or "Nowel") entered English in the late 14th century and is from the Old French noël or naël, itself ultimately from the Latin nātālis (diēs) meaning "birth (day)".
Nativity of Jesus
Gospel according to Saint Luke Chapter 2, v 1–20
The gospels of Luke and Matthew describe Jesus as being born in Bethlehem to the Virgin Mary. In Luke, Joseph and Mary travel from Nazareth to Bethlehem for the census, and Jesus is born there and laid in a manger. Angels proclaimed him a savior for all people, and shepherds came to adore him.
Matthew adds that the magi follow a star to Bethlehem to bring gifts to Jesus, born the king of the Jews. King Herod orders the massacre of all the boys less than two years old in Bethlehem, but the family flees to Egypt and later returns to Nazareth.
History
The nativity sequences included in the Gospels of Matthew and Luke prompted early Christian writers to suggest various dates for the anniversary. Although no date is indicated in the gospels, early Christians connected Jesus to the Sun through the use of such phrases as "Sun of righteousness." The Romans marked the winter solstice on December 25. The first recorded Christmas celebration was in Rome on December 25, AD 336. In the 3rd century, the date of the nativity was the subject of great interest. Around AD 200, Clement of Alexandria wrote:
Some have determined not only the year of our Lord's birth, but also the day; and they say that it took place in the 28th year of Augustus, and in the 25th day of the Egyptian month Pachon May 20 Further, others say that He was born on the 24th or 25th of Pharmuthi April 20 or 21.
Various factors contributed to the selection of December 25 as a date of celebration: it was the date of the winter solstice on the Roman calendar and it was nine months after March 25, the date of the vernal equinox and a date linked to the conception of Jesus (celebrated as the Feast of the Annunciation).
Christmas played a role in the Arian controversy of the fourth century. After this controversy ran its course, the prominence of the holiday declined for a few centuries. The feast regained prominence after 800 when Charlemagne was crowned emperor on Christmas Day.
In Puritan England, Christmas was banned as it was associated with drunkenness and other misbehavior. It was restored as a legal holiday in England in 1660 but remained disreputable in the minds of many people. In the early 19th century, Christmas festivities and services became widespread with the rise of the Oxford Movement in the Church of England that emphasized the centrality of Christmas in Christianity and charity to the poor, along with Washington Irving, Charles Dickens, and other authors emphasizing family, children, kind-heartedness, gift-giving, and Santa Claus (for Irving), or Father Christmas (for Dickens).
Introduction
Christmas does not appear on the lists of festivals given by the early Christian writers Irenaeus and Tertullian. Origen and Arnobius fault the pagans for celebrating birthdays, which suggests that Christmas was not celebrated in their time. Arnobius wrote after AD 297. The Chronograph of 354 records that a Christmas celebration took place in Rome in 336, eight days before the calends of January.
In the East, the birth of Jesus was celebrated in connection with the Epiphany on January 6. This holiday was not primarily about the nativity, but rather the baptism of Jesus. Christmas was promoted in the East as part of the revival of Orthodox Christianity that followed the death of the pro-Arian Emperor Valens at the Battle of Adrianople in 378. The feast was introduced in Constantinople in 379, in Antioch by John Chrysostom towards the end of the fourth century, probably in 388, and in Alexandria in the following century.
Solstice date
December 25 was the date of the winter solstice in the Roman calendar. A late fourth-century sermon by Saint Augustine explains why this was a fitting day to celebrate Christ's nativity: "Hence it is that He was born on the day which is the shortest in our earthly reckoning and from which subsequent days begin to increase in length. He, therefore, who bent low and lifted us up chose the shortest day, yet the one whence light begins to increase."
Linking Jesus to the Sun was supported by various Biblical passages. Jesus was considered to be the "Sun of righteousness" prophesied by Malachi: "Unto you shall the sun of righteousness arise, and healing is in his wings."
Such solar symbolism could support more than one date of birth. An anonymous work known as De Pascha Computus (243) linked the idea that creation began at the spring equinox, on March 25, with the conception or birth (the word nascor can mean either) of Jesus on March 28, the day of the creation of the sun in the Genesis account. One translation reads: "O the splendid and divine providence of the Lord, that on that day, the very day, on which the sun was made, March 28, a Wednesday, Christ should be born".
In the 17th century, Isaac Newton, who, coincidentally, was born on December 25, argued that the date of Christmas may have been selected to correspond with the solstice.
Conversely, according to Steven Hijmans of the University of Alberta, "It is cosmic symbolism ... which inspired the Church leadership in Rome to elect the southern solstice, December 25, as the birthday of Christ, and the northern solstice as that of John the Baptist, supplemented by the equinoxes as their respective dates of conception."
Calculation hypothesis
The calculation hypothesis suggests that an earlier holiday held on March 25 became associated with the Incarnation. Christmas was then calculated as nine months later. The calculation hypothesis was proposed by French writer Louis Duchesne in 1889. In modern times, March 25 is celebrated as Annunciation. This holiday was created in the seventh century and was assigned to a date that is nine months before Christmas, in addition to being the traditional date of the equinox. It is unrelated to the Quartodeciman, which had been forgotten by this time. Forgotten by everyone except the Jews, of course, who continued to observe Passover; also a Quartodeciman feast.
Early Christians celebrated the life of Jesus on a date considered equivalent to 14 Nisan (Passover) on the local calendar. Because Passover was held on the 14th of the month, this feast is referred to as the Quartodeciman. All the major events of Christ's life, especially the passion, were celebrated on this date. In his letter to the Corinthians, Paul mentions Passover, presumably celebrated according to the local calendar in Corinth. Tertullian (d. 220), who lived in Latin-speaking North Africa, gives the date of passion celebration as March 25. The date of the passion was moved to Good Friday in 165 when Pope Soter created Easter by reassigning the Resurrection to a Sunday. According to the calculation hypothesis, the celebration of the Quartodeciman continued in some areas and the feast became associated with Incarnation.
The calculation hypothesis is considered academically to be "a thoroughly viable hypothesis", though not certain. It was a traditional Jewish belief that great men were born and died on the same day, so lived a whole number of years, without fractions: Jesus was therefore considered to have been conceived on March 25, as he died on March 25, which was calculated to have coincided with 14 Nisan. A passage in Commentary on the Prophet Daniel (204) by Hippolytus of Rome identifies December 25 as the date of the nativity. This passage is generally considered a late interpellation. But the manuscript includes another passage, one that is more likely to be authentic, that gives the passion as March 25.
In 221, Sextus Julius Africanus (c. 160 – c. 240) gave March 25 as the day of creation and of the conception of Jesus in his universal history. This conclusion was based on solar symbolism, with March 25 the date of the equinox. As this implies a birth in December, it is sometimes claimed to be the earliest identification of December 25 as the nativity. However, Africanus was not such an influential writer that it is likely he determined the date of Christmas.
History of religions hypothesis
The rival "History of Religions" hypothesis suggests that the Church selected December 25 date to appropriate festivities held by the Romans in honor of the Sun god Sol Invictus. This cult was established by Aurelian in 274. An explicit expression of this theory appears in an annotation of uncertain date added to a manuscript of a work by 12th-century Syrian bishop Jacob Bar-Salibi. The scribe who added it wrote:
It was a custom of the Pagans to celebrate on the same 25 December the birthday of the Sun, at which they kindled lights in token of festivity. In these solemnities and revelries, the Christians also took part. Accordingly, when the doctors of the Church perceived that the Christians had a leaning toward this festival, they took counsel and resolved that the true Nativity should be solemnized on that day.
In 1743, German Protestant Paul Ernst Jablonski argued Christmas was placed on December 25 to correspond with the Roman solar holiday Dies Natalis Solis Invicti and was, before therefore, a "paganization" that debased the true church. However, it has been also argued that, on the contrary, Emperor Aurelian, who in 274 instituted the holiday of the Dies Natalis Solis Invicti, did so partly as an attempt to give a pagan significance to a date already important for Christians in Rome.
Hermann Usener and others proposed that the Christians chose this day because it was the Roman feast celebrating the birthday of Sol Invictus. Modern scholar S. E. Hijmans, however, states that "While they were aware that pagans called this day the 'birthday' of Sol Invictus, this did not concern them and it did not play any role in their choice of date for Christmas." Moreover, Thomas J. Talley holds that the Roman Emperor Aurelian placed a festival of Sol Invictus on December 25 to compete with the growing rate of the Christian Church, which had already been celebrating Christmas on that date first. In the judgment of the Church of England Liturgical Commission, the History of Religions hypothesis has been challenged by a view based on an old tradition, according to which the date of Christmas was fixed at nine months after March 25, the date of the vernal equinox, on which the Annunciation was celebrated.
Concerning a December religious feast of the deified Sun (Sol), as distinct from a solstice feast of the birth (or rebirth) of the astronomical sun, Hijmans has commented that "while the winter solstice on or around December 25 was well established in the Roman imperial calendar, there is no evidence that a religious celebration of Sol on that day antedated the celebration of Christmas". "Thomas Talley has shown that, although the Emperor Aurelian's dedication of a temple to the sun god in the Campus Martius (C.E. 274) probably took place on the 'Birthday of the Invincible Sun' on December 25, the cult of the sun in pagan Rome ironically did not celebrate the winter solstice nor any of the other quarter-tense days, as one might expect." The Oxford Companion to Christian Thought remarks on the uncertainty about the order of precedence between the religious celebrations of the Birthday of the Unconquered Sun and the birthday of Jesus, stating that the hypothesis that December 25 was chosen for celebrating the birth of Jesus based on the belief that his conception occurred on March 25 "potentially establishes 25 December as a Christian festival before Aurelian's decree, which, when promulgated, might have provided for the Christian feast both opportunity and challenge".
Relation to concurrent celebrations
Many popular customs associated with Christmas developed independently of the commemoration of Jesus' birth, with some claiming that certain elements have origins in pre-Christian festivals that were celebrated by pagan populations who were later converted to Christianity. The prevailing atmosphere of Christmas has also continually evolved since the holiday's inception, ranging from a sometimes raucous, drunken, carnival-like state in the Middle Ages, to a tamer family-oriented and children-centered theme introduced in a 19th-century transformation. The celebration of Christmas was banned on more than one occasion within certain groups, such as the Puritans and Jehovah's Witnesses (who do not celebrate birthdays in general), due to concerns that it was too unbiblical.
Before and through the early Christian centuries, winter festivals were the most popular of the year in many European pagan cultures. Reasons included the fact that less agricultural work needed to be done during the winter, as well as an expectation of better weather as spring approached. Celtic winter herbs such as mistletoe and ivy, and the custom of kissing under a mistletoe, are common in modern Christmas celebrations in English-speaking countries.
The pre-Christian Germanic peoples—including the Anglo-Saxons and the Norse—celebrated a winter festival called Yule, held in the late December to early January period, yielding modern English yule, today used as a synonym for Christmas. In Germanic language-speaking areas, numerous elements of modern Christmas folk custom and iconography may have originated from Yule, including the Yule log, Yule boar, and the Yule goat. Often leading a ghostly procession through the sky (the Wild Hunt), the long-bearded god Odin is referred to as "the Yule one" and "Yule father" in Old Norse texts, while other gods are referred to as "Yule beings". On the other hand, as there are no reliable existing references to a Christmas log before the 16th century, the burning of the Christmas block may have been an early modern invention by Christians unrelated to the pagan practice.
In eastern Europe also, old pagan traditions were incorporated into Christmas celebrations, an example being the Koleda, which was incorporated into the Christmas carol.
Post-classical history
The Nativity, from a 14th-century Missal; a liturgical book containing texts and music necessary for the celebration of Mass throughout the year
In the Early Middle Ages, Christmas Day was overshadowed by Epiphany, which in western Christianity focused on the visit of the magi. But the medieval calendar was dominated by Christmas-related holidays. The forty days before Christmas became the "forty days of St. Martin" (which began on November 11, the feast of St. Martin of Tours), now known as Advent. In Italy, former Saturnalian traditions were attached to Advent. Around the 12th century, these traditions transferred again to the Twelve Days of Christmas (December 25 – January 5); a time that appears in the liturgical calendars as Christmastide or Twelve Holy Days.
The prominence of Christmas Day increased gradually after Charlemagne was crowned Emperor on Christmas Day in 800. King Edmund the Martyr was anointed on Christmas in 855 and King William I of England was crowned on Christmas Day 1066. The coronation of Charlemagne on Christmas of 800 helped promote the popularity of the holiday. By the High Middle Ages, the holiday had become so prominent that chroniclers routinely noted where various magnates celebrated Christmas. King Richard II of England hosted a Christmas feast in 1377 at which twenty-eight oxen and three hundred sheep were eaten. The Yule boar was a common feature of medieval Christmas feasts. Caroling also became popular and was originally performed by a group of dancers who sang. The group was composed of a lead singer and a ring of dancers that provided the chorus. Various writers of the time condemned caroling as lewd, indicating that the unruly traditions of Saturnalia and Yule may have continued in this form. "Misrule"—drunkenness, promiscuity, gambling—was also an important aspect of the festival. In England, gifts were exchanged on New Year's Day, and there was a special Christmas ale.
Christmas during the Middle Ages was a public festival that incorporated ivy, holly, and other evergreens. Christmas gift-giving during the Middle Ages was usually between people with legal relationships, such as tenants and landlords. The annual indulgence in eating, dancing, singing, sporting, and card playing escalated in England, and by the 17th century, the Christmas season featured lavish dinners, elaborate masques, and pageants. In 1607, King James I insisted that a play be acted on Christmas night and that the court indulge in games. It was during the Reformation in 16th–17th-century Europe that many Protestants changed the gift bringer to the Christ Child or Christkindl, and the date of giving gifts changed from December 6 to Christmas Eve.
Church attendance
Christmas Day (inclusive of its vigil, Christmas Eve), is a Festival in the Lutheran Churches, a holy day of obligation in the Roman Catholic Church, and a Principal Feast of the Anglican Communion. Other Christian denominations do not rank their feast days but place importance on Christmas Eve/Christmas Day, as with other Christian feasts like Easter, Ascension Day, and Pentecost. As such, for Christians, attending a Christmas Eve or Christmas Day church service plays an important part in the recognition of the Christmas season. Christmas, along with Easter, is the period of highest annual church attendance. A 2010 survey by LifeWay Christian Resources found that six in ten Americans attend church services during this time.
Cards
Christmas cards are illustrated messages of greeting exchanged between friends and family members during the weeks preceding Christmas Day. The traditional greeting reads "wishing you a Merry Christmas and a Happy New Year", much like that of the first commercial Christmas card, produced by Sir Henry Cole in London in 1843. The custom of sending them has become popular among a wide cross-section of people with the emergence of the modern trend towards exchanging E-cards.
Christmas cards are purchased in considerable quantities and feature artwork, commercially designed and relevant to the season. The content of the design might relate directly to the Christmas narrative, with depictions of the Nativity of Jesus, or Christian symbols such as the Star of Bethlehem, or a white dove, which can represent both the Holy Spirit and Peace on Earth. Other Christmas cards are more secular and can depict Christmas traditions, mythical figures such as Santa Claus, objects directly associated with Christmas such as candles, holly, and baubles, or a variety of images associated with the season, such as Christmastide activities, snow scenes, and the wildlife of the northern winter. There are even humorous cards and genres depicting nostalgic scenes of the past such as crinolined shoppers in idealized 19th-century streetscapes.
Some prefer cards with a poem, prayer, or Biblical verse; while others distance themselves from religion with an all-inclusive "Season's greetings".
Gift giving
The exchanging of gifts is one of the core aspects of the modern Christmas celebration, making it the most profitable time of year for retailers and businesses throughout the world. On Christmas, people exchange gifts based on the Christian tradition associated with Saint Nicholas, and the gifts of gold, frankincense, and myrrh which were given to the baby Jesus by the Magi. The practice of gift-giving in the Roman celebration of Saturnalia may have influenced Christian customs, but on the other hand the Christian "core dogma of the Incarnation, however, solidly established the giving and receiving of gifts as the structural principle of that recurrent yet unique event", because it was the Biblical Magi, "together with all their fellow men, who received the gift of God through man's renewed participation in the divine life."
Gift-bearing figures
Several figures are associated with Christmas and the seasonal giving of gifts. Among these are Father Christmas, also known as Santa Claus (derived from the Dutch for Saint Nicholas), Père Noël, and the Weihnachtsmann; Saint Nicholas or Sinterklaas; the Christkind; Kris Kringle; Joulupukki; tomte/nisse; Babbo Natale; Saint Basil; and Ded Moroz. The Scandinavian tomte (also called nisse) is sometimes depicted as a gnome instead of Santa Claus. The best known of these figures today is red-dressed Santa Claus, of diverse origins. The name Santa Claus can be traced back to the Dutch Sinterklaas, which means simply Saint Nicholas. Nicholas was a 4th-century Greek bishop of Myra, a city in the Roman province of Lycia, whose ruins are 3 kilometers (1.9 mi) from modern Demre in southwest Turkey. Among other saintly attributes, he was noted for the care of children, generosity, and the giving of gifts. His feast day, December 6, came to be celebrated in many countries with the giving of gifts.
Saint Nicholas traditionally appeared in bishop's attire, accompanied by helpers, inquiring about the behavior of children during the past year before deciding whether they deserved a gift or not. By the 13th century, Saint Nicholas was well known in the Netherlands, and the practice of gift-giving in his name spread to other parts of central and southern Europe. At the Reformation in 16th–17th-century Europe, many Protestants changed the gift bringer to the Christ Child or Christkindl, corrupted in English to Kris Kringle, and the date of giving gifts changed from December 6 to Christmas Eve.
The modern popular image of Santa Claus, however, was created in the United States, and in particular in New York. The transformation was accomplished with the aid of notable contributors including Washington Irving and the German-American cartoonist Thomas Nast (1840–1902). Following the American Revolutionary War, some of the inhabitants of New York City sought out symbols of the city's non-English past. New York had originally been established as the Dutch colonial town of New Amsterdam and the Dutch Sinterklaas tradition was reinvented as Saint Nicholas.
Current tradition in several Latin American countries (such as Venezuela and Colombia) holds that while Santa makes the toys, he then gives them to the Baby Jesus, who is the one who actually delivers them to the children's homes, a reconciliation between traditional religious beliefs and the iconography of Santa Claus imported from the United States.
In South Tyrol (Italy), Austria, Czech Republic, Southern Germany, Hungary, Liechtenstein, Slovakia, and Switzerland, the Christkind (Ježíšek in Czech, Jézuska in Hungarian and Ježiško in Slovak) brings the presents. Greek children get their presents from Saint Basil on New Year's Eve, the eve of that saint's liturgical feast. The German St. Nikolaus is not identical with the Weihnachtsmann (who is the German version of Santa Claus / Father Christmas). St. Nikolaus wears a bishop's dress and still brings small gifts (usually candies, nuts, and fruits) on December 6 and is accompanied by Knecht Ruprecht. Although many parents around the world routinely teach their children about Santa Claus and other gift bringers, some have come to reject this practice, considering it deceptive.
Multiple gift-giver figures exist in Poland, varying between regions and individual families. St Nicholas (Święty Mikołaj) dominates Central and North-East areas, the Starman (Gwiazdor) is most common in Greater Poland, Baby Jesus (Dzieciątko) is unique to Upper Silesia, with the Little Star (Gwiazdka) and the Little Angel (Aniołek) being common in the South and the South-East. Grandfather Frost (Dziadek Mróz) is less commonly accepted in some areas of Eastern Poland. It is worth noting that across all of Poland, St Nicholas is the gift giver on Saint Nicholas Day on December 6.
Date according to Julian calendar
Some jurisdictions of the Eastern Orthodox Church, including those of Russia, Georgia, Ukraine, Macedonia, Montenegro, Serbia, and Jerusalem, mark feasts using the older Julian calendar. As of 2021, there is a difference of 13 days between the Julian calendar and the modern Gregorian calendar, which is used internationally for most secular purposes. As a result, December 25 on the Julian calendar currently corresponds to January 7 on the calendar used by most governments and people in everyday life. Therefore, the aforementioned Orthodox Christians mark December 25 (and thus Christmas) on the day that is internationally considered to be January 7.
However, other Orthodox Christians, such as those belonging to the jurisdictions of Constantinople, Bulgaria, Greece, Romania, Antioch, Alexandria, Albania, Cyprus, Finland, and the Orthodox Church in America, among others, began using the Revised Julian calendar in the early 20th century, which at present corresponds exactly to the Gregorian calendar. Therefore, these Orthodox Christians mark December 25 (and thus Christmas) on the same day that is internationally considered to be December 25, and which is also the date of Christmas among Western Christians.
A further complication is added by the fact that the Armenian Apostolic Church continues the original ancient Eastern Christian practice of celebrating the birth of Christ not as a separate holiday, but on the same day as the celebration of his baptism (Theophany), which is on January 6. This is a public holiday in Armenia, and it is held on the same day that is internationally considered to be January 6, because the Armenian Church in Armenia uses the Gregorian calendar.
However, there is also a small Armenian Patriarchate of Jerusalem, which maintains the traditional Armenian custom of celebrating the birth of Christ on the same day as Theophany (January 6) but uses the Julian calendar for the determination of that date. As a result, this church celebrates "Christmas" (more properly called Theophany) on the day that is considered January 19 on the Gregorian calendar in use by the majority of the world.
