Calculating Christmas
            
William J. Tighe on the Story Behind December 25
 
            
Many Christians think that Christians celebrate Christ’s birth on 
            
December 25th because the church fathers appropriated the date of a 
            
pagan festival. Almost no one minds, except for 
a few groups on the 
            
fringes of American Evangelicalism, who seem to 
think that this 
            
makes Christmas itself a pagan festival. But it 
is perhaps 
            
interesting to know that the choice of December 
25th is the result 
            
of attempts among the earliest Christians to 
figure out the date of 
            
Jesus’ birth based on calendrical calculations that had nothing to 
            
do with pagan festivals.
            
Rather, the pagan festival of the “Birth of the Unconquered Son” 
            
instituted by the Roman Emperor Aurelian on 25 
December 274, was 
            
almost certainly an attempt to create a pagan 
alternative to a date 
            
that was already of some significance to Roman 
Christians. Thus the 
            
“pagan origins of Christmas” is a myth without 
historical substance.
 
            
A Mistake
 
            
The idea that the date was taken from the pagans goes back to two 
            
scholars from the late seventeenth and early 
eighteenth centuries. 
            
Paul Ernst Jablonski, a German Protestant, wished to show that the 
            
celebration of Christ’s birth on December 25th 
was one of the many 
            
“paganizations” of 
Christianity that the Church of the fourth 
            
century embraced, as one of many “degenerations” 
that transformed 
            
pure apostolic Christianity into Catholicism. 
Dom Jean Hardouin, a 
            
Benedictine monk, tried to show that the Catholic Church adopted 
            
pagan festivals for Christian purposes without 
paganizing the                                 
            
Gospel. In the Julian calendar, created in 45 B.C. under Julius Caesar, 
the 
            
winter solstice fell on December 25th, and it 
therefore seemed 
            
obvious to Jablonski and Hardouin that the day must have had a pagan 
            
significance before it had a Christian one. But 
in fact, the date 
            
had no religious significance in the Roman pagan 
festal calendar 
            
before Aurelian’s time, nor did the cult of the 
sun play a prominent 
            
role in Rome before him.
            
There were two temples of the sun in Rome, one of which (maintained 
            
by the clan into which Aurelian was born or 
adopted) celebrated its 
            
dedication festival on August 9th, the other of 
which celebrated its 
            
dedication festival on August 28th. But both of 
these cults fell 
            
into neglect in the second century, when eastern 
cults of the sun, 
            
such as Mithraism, began to win a following in 
Rome. And in any 
            
case, none of these cults, old or new, had 
festivals associated with 
            
solstices or equinoxes.
            
As things actually happened, Aurelian, who ruled from 270 until his 
            
assassination in 275, was hostile to 
Christianity and appears to 
            
have promoted the establishment of the festival 
of the “Birth of the 
            
Unconquered Sun” as a device to unify the various pagan cults of the 
            
Roman Empire around a commemoration of the annual “rebirth” of the 
            
sun. He led an empire that appeared to be 
collapsing in the face of 
            
internal unrest, rebellions in the provinces, 
economic decay, and 
            
repeated attacks from German tribes to the north 
and the Persian 
            
Empire to the east.
            
In creating the new feast, he intended the beginning of the 
            lengthening of the daylight, and the arresting of the 
lengthening of 
            
darkness, on December 25th to be a symbol of the 
hoped-for 
            
“rebirth,” or perpetual rejuvenation, of the 
Roman Empire, resulting 
            
from the maintenance of the worship of the gods 
whose tutelage (the 
            
Romans thought) had brought Rome to greatness and world-rule. If it 
            
co-opted the Christian celebration, so much the 
better.
          
            
A By-Product
 
            
It is true that the first evidence of Christians celebrating 
            
December 25th as the date of the Lord’s nativity comes from Rome 
            
some years after Aurelian, in A.D. 336, but 
there is evidence from 
            
both the Greek East and the Latin West that 
Christians attempted to 
            
figure out the date of Christ’s birth long 
before they began to 
            
celebrate it liturgically, even in the second 
and third centuries. 
            
The evidence indicates, in fact, that the attribution of the date of 
            
December 25th was a by-product of attempts to determine when to 
            
celebrate his death and 
resurrection.
            
How did this happen? There is a seeming contradiction between the 
            
date of the Lord’s death as given in the 
synoptic Gospels and in 
            
John’s Gospel. The synoptics would appear to 
place it on Passover 
            
Day (after the Lord had celebrated the Passover Meal on the 
            
preceding evening), and John on the Eve of 
Passover, just when the 
            
Passover lambs were being slaughtered in the Jerusalem Temple for 
            
the feast that was to ensue after sunset on that 
day.
            
Solving this problem involves answering the question of whether the 
            
Lord’s Last Supper was a Passover Meal, or a meal celebrated a day 
            
earlier, which we cannot enter into here. 
Suffice it to say that the 
            
early Church followed John rather than the synoptics, and thus 
            
believed that Christ’s death would have taken 
place on 14 Nisan, 
            
according to the Jewish lunar calendar. (Modern 
scholars agree, by 
            
the way, that the death of Christ could have 
taken place only in 
            
A.D. 30 or 33, as those two are the only years of that time when the 
            
eve of Passover could have fallen on a Friday, 
the possibilities 
            
being either 7 April 30 or 3 April 
33.)
            
However, as the early Church was forcibly separated from Judaism, it 
            
entered into a world with different calendars, 
and had to devise its 
            
own time to celebrate the Lord’s Passion, not 
least so as to be 
            
independent of the rabbinic calculations of the 
date of Passover. 
            
Also, since the Jewish calendar was a lunar calendar consisting of 
            
twelve months of thirty days each, every few 
years a thirteenth 
            
month had to be added by a decree of the 
Sanhedrin to keep the 
            
calendar in synchronization with the equinoxes 
and solstices, as 
            
well as to prevent the seasons from “straying” 
into inappropriate 
            
months.
            
Apart from the difficulty Christians would have had in following—or 
            
perhaps even being accurately informed about—the 
dating of Passover 
            
in any given year, to follow a lunar calendar of 
their own devising 
            
would have set them at odds with both Jews and 
pagans, and very 
            
likely embroiled them in endless disputes among 
themselves. (The 
            
second century saw severe disputes about whether 
Pascha had always 
            
to fall on a Sunday or on whatever weekday 
followed two days after 
            
14 Artemision/Nisan, but to have followed a 
lunar calendar would 
            
have made such problems much 
worse.)
            
These difficulties played out in different ways among the Greek 
            
Christians in the eastern part of the empire and the Latin 
         
   Christians in the 
western part of it. Greek Christians seem to have 
            
wanted to find a date equivalent to 14 Nisan in 
their own solar 
            
calendar, and since Nisan was the month in which 
the spring equinox 
            
occurred, they chose the 14th day of Artemision, the month in which 
            
the spring equinox invariably fell in their own 
calendar. Around 
            
A.D. 300, the Greek calendar was superseded by the Roman calendar, 
            
and since the dates of the beginnings and 
endings of the months in 
            
these two systems did not coincide, 14 Artemision became April 6th.
            
In contrast, second-century Latin Christians in Rome and North 
            
Africa appear to have desired to establish the historical date on 
            
which the Lord Jesus died. By the time of 
Tertullian they had 
            
concluded that he died on Friday, 25 March 29. 
(As an aside, I will 
            
note that this is impossible: 25 March 29 was 
not a Friday, and 
            Passover Eve in A.D. 
29 did not fall on a Friday and was not on 
            
March 25th, or in March at all.)
 
            
Integral Age
 
            
So in the East we have April 6th, in the West, March 25th. At this 
            
point, we have to introduce a belief that seems 
to have been 
            
widespread in Judaism at the time of Christ, but 
which, as it is 
            
nowhere taught in the Bible, has completely 
fallen from the 
            
awareness of Christians. The idea is that of the 
“integral age” of 
            
the great Jewish prophets: the idea that the 
prophets of Israel died 
            
on the same dates as their birth or 
conception.
            
This notion is a key factor in understanding how some early 
            
Christians came to believe that December 25th is the date of 
            
Christ’s birth. The early Christians applied this idea to Jesus, so 
            
that March 25th and April 6th were not only the 
supposed dates of 
            
Christ’s death, but of his conception or birth as well. There is 
            
some fleeting evidence that at least some first- 
and second-century 
            
Christians thought of March 25th or April 6th as the date of 
            
Christ’s birth, but rather quickly the assignment of March 25th as 
            
the date of Christ’s conception 
prevailed.
            
It is to this day, commemorated almost universally among Christians 
            
as the Feast of the Annunciation, when the 
Archangel Gabriel brought 
            the good tidings of a savior to the Virgin Mary, upon whose 
            
acquiescence the Eternal Word of God (“Light of 
Light, True God of 
            
True God, begotten of the Father before all ages”) forthwith became 
            
incarnate in her womb. What is the length of 
pregnancy? Nine months. 
            
Add nine months to March 25th and you get December 25th; add it to 
            
April 6th and you get January 6th. December 25th is Christmas, and 
            
January 6th is Epiphany.
            
Christmas (December 25th) is a feast of Western Christian origin. In 
            
Constantinople it appears to have been introduced in 379 or 380. 
            
From a sermon of St. John Chrysostom, at the time a renowned ascetic 
            
and preacher in his native Antioch, it appears 
that the feast was 
            
first celebrated there on 25 December 386. From 
these centers it 
            
spread throughout the Christian East, being 
adopted in Alexandria 
            
around 432 and in Jerusalem a century or more 
later. The Armenians, 
            
alone among ancient Christian churches, have 
never adopted it, and 
            
to this day celebrate Christ’s birth, 
manifestation to the magi, and 
            
baptism on January 6th.
        
    Western 
churches, in turn, gradually adopted the January 6th 
            
Epiphany feast from the East, Rome doing so sometime between 366 and 
            
394. But in the West, the feast was generally presented as the 
            
commemoration of the visit of the magi to the 
infant Christ, and as 
            
such, it was an important feast, but not one of 
the most important 
            
ones—a striking contrast to its position in the 
East, where it 
            
remains the second most important festival of 
the church year, 
            
second only to Pascha 
(Easter).
            
In the East, Epiphany far outstrips Christmas. The reason is that 
            
the feast celebrates Christ’s baptism in the 
Jordan and the occasion 
            
on which the Voice of the Father and the Descent 
of the Spirit both 
            
manifested for the first time to mortal men the 
divinity of the 
            
Incarnate Christ and the Trinity of the Persons in the One 
Godhead.
 
            
A Christian Feast
 
         
   Thus, December 25th 
as the date of the Christ’s birth appears to owe 
            
nothing whatsoever to pagan influences upon the 
practice of the 
            
Church during or after Constantine’s time. It is wholly unlikely to 
            
have been the actual date of Christ’s birth, but 
it arose entirely 
            
from the efforts of early Latin Christians to 
determine the 
            
historical date of Christ’s 
death.
            
And the pagan feast which the Emperor Aurelian instituted on that 
            
date in the year 274 was not only an effort to 
use the winter 
            
solstice to make a political statement, but also 
almost certainly an 
            
attempt to give a pagan significance to a date 
already of importance 
            to Roman Christians. The Christians, in turn, could at a 
later date 
            
re-appropriate the pagan “Birth of the 
Unconquered Sun” to refer, on 
            
the occasion of the birth of Christ, to the 
rising of the “Sun of

 The decision to celebrate Christmas on 
December 25 was made at Ephesus (Third Ecumenical) Church Council in the year 
431.
 
A 
key role in implementing a separate Christmas celebration in the East was played 
by three Eastern Church Fathers: St. Basil the Great, Gregory the Theologian and 
John Chrysostom. Under the influence of St. Gregory the Theologian this feast 
was introduced in Constantinople. In Jerusalem, Christmas was celebrated with 
Epiphany up to 634. In the fourth century Saint Helena, the mother of Emperor 
Constantine the Great, built a church in Bethlehem.
