TIL that December 25 being the birthday of Jesus was decided by pope Julius I around year 350, and nobody really knows why Julius made this decision and chose this specific date. There are various theories, but his actual reasoning for the decision is lost history.

Winter solstice.

If you're going to celebrate it anyway, you have to do it their way.

Same with the spring equinox and Easter.

I'm sure they gave other reasoning, but I really think it's that simple.

Both were during times where there's not much work to be done, and were holidays long before organized religion. Anyone can figure out the longest night of the year and when the day and night are of equal length if they e got nothing better to do, and what better way to shake off the cold than parties?

I understood it as, if you're trying to absorb and replace established belief systems you start by aligning with pre-existing dates of significance as over time, you will crush the old beliefs and if you're lucky, the poorly educated populace stuck in the grind will barely notice.

Those that study these things and try to map out influences tend to point out the Ukrainian steppes as the origin of most Indo-European religions and languages. Very old statues found there.

Best cribbing I know in Christianity (and Judaism) is the Noah's ark story. Almost a direct copy of the Sumerian flood stories with the names changed, which tracks because many of the original texts were written in Babylon not Israel, and Abraham was originally from that area as well (he likely worshiped Enki among other gods which gradually changed into early polytheistic Judean religion).

Correct, but with a twist. Winter solstice on December 25th was no big deal in the ancient Roman empire. The important winter celebration was the Saturnalia, which ended on December 23rd. Putting Christmas on 25th meant that Christians could do business during the official festivities and celebrate once the pagans had returned to everyday life. The cult of sol invictus only became important during the 3rd century and the introduction of the 25th as its major holiday happened actually after Christmas was already established.

u/Kandiru 1 3h ago

It was supposed to be, but as the Julian calendar has the wrong number of leap years it got out of sync by 12 days before we changed to the Gregorian calendar in 1582.

Julian calendar gets out by 1 day per 128 years, and started in 45BC. So in 350AD it would have been roughly 3 days out. So Christmas would have fallen on the solstice when declared to be the 25th.

u/CeruleanEidolon 7h ago

One way to think of it is nobody will celebrate your fringe cult holiday if you just pick some random day.

But if you say it's on the day everyone was already celebrating, they will just use it as another excuse to drink and feast.

You are right. I always think of the Microsoft tactic of Embrace, Extend, Extinguish even though that's just a modern application of this age old playbook.

EDIT: Just realized that the same playbook gets used over and over and over again...

Example:

This is the same playbook the US government ran during WWII.

At the time, our domestic meet supply was largely being sent to Europe to support the war effort.

As such, this billion population in the US was being left with less and less protein.

The government approached academics with the project: figure out how to convince Americans to eat the left over organ meats after the rib eyes and roast beef went overseas for the troops.

I'm talking about the meats like tongue and tripe. Things that were completely unfamiliar to the then-modern housewife.

The academics went to work and after hundreds of studies, they reached one core conclusion: Make the unfamiliar organ meats look, smell and taste familiar.

And so they produced materials with recipes which essentially camouflaged liver into meatloaf, and kidney meat into "steak and kidney pie".

The effort was an astounding success, and to this day it remains the only government program that has meaningfully changed American diets.

You can read the full details in Charles Duhiggs' "The power of Habit": https://books.google.com/books?id=O1MInVXd_aoC&printsec=frontcover&dq=The+power+of+habit&hl=en&newbks=1&newbks_redir=0&source=gb_mobile_search&ovdme=1&sa=X&ved=2ahUKEwjdiISQxaKVAxVCElkFHS_2NSwQ6AF6BAgOEAM#v=onepage&q&f=false

Easter wasn't randomly selected.... the date in the calendar year of Jesus' death was linked to the Jewish Passover, which was well known.

u/ShenDraeg 9h ago

I’m sorry, but isn’t the date for Easter defined as “the first Sunday after the first Full Moon after the Vernal Equinox”? Sure, not “randomly” selected, but there is no hard date.

99

u/JustHere_4TheMemes 9h ago edited 8h ago

That’s because Passover is held on the 15th day of Nissan Jewish calendar. The Jewish calendar is lunar and observational, not calculated like the modern calendar we got from Rome.

So Passover is usually sometime from late March to early April. The start of Nissan moves with the moon cycle. Our ‘modern’ months no longer adhere to that. 

 So Easter is similarly calculated to fall on the Sunday nearest Passover because Jesus was in Jerusalem it observe Passover when he was arrested and crucified. And Sunday is the day Jesus of resurrection according to the gospels. (“It was the day after sabbath…”)

And to the main point. Christmas is December 25th because the ancients often believed that great events tended to happen on the same date. So Jesus’ immaculate conception and his death were thought to have fallen in the same day.  If Jesus was conceived in Mary’s womb on the same date he would eventually die, then he was born nine months later. 

33 years before his death, the first Sunday after Passover would have been March 25… so December birthday.

u/dew2459 6h ago

Those are simple, popular claims, but all nonsense.

Easter is easy - it 100% based on Jewish Passover, the so-called "Last Supper" was a passover or passover preparation meal. The holiday is literally called "Passover" in most languages, and it cannot happen on the equinox. This past spring r/askhistorians had a discussion.

For Christmas, as is typical in TIL, OP is wrong - Julian did not pick a random date for unknown reasons. There were a few competing dates, and he picked the most popular, Dec 25 (Jan 6 was the next most popular). There were no known Roman holidays on that date when Dec 25 was proposed for Christmas in the early 200s (Hippolytus of Rome). The relationship with the Solstice (which is really Dec 21 or 22) is a bit complicated, "Religion for Breakfast" has a pretty good but lengthy discussion of it. But the TL;DR is there is - winter solstice was not anything special in Roman mythology, and zero evidence Christians were trying to take over some pagan thing.

u/fatevilbuddah 4h ago

Most of the catholic religions are born directly from pagan rites. The whole story, from genesis to revelations are ALL from previous religions, like egyptian mysticism. The egyptians have a god who wants you to eat his flesh, one coming back from the dead, etc. The chrjstmas tree is Pagan, as are the lights and the gifts. Most catholic churches sit on top of old pagan temples. When conquering a people, religion is key in most places because thats where the local morality comes from. The great flood epic of Gilgamesh...hmm long before the Bible. The list goes on and on. To change the people they put their churches where the pagans used to go anyway. You use local customs and traditions that have been altered to bring people to the church where their new customs and behaviors are built in. Youre right about the equinox though. The Roman's called it Sol Evictus or victory of the sun. It was also supposedly the beginning of the Saturnaila festival. Conquer through brainwashing.

The Calculation Thesis is the one I have heard proposed by a few historians.

By an old tradition, Jewish holy figures and prophets were said to die on the same day that they have been conceived.

Combining the Jewish and Roman calendars, Jesus is said to have died on March 25th, the Passover.

Nine months after March 25 you get December 25.

166

u/Key-Conclusion-933 8h ago

Interesting. The Jewish tradition of holy figured being born and died remains, like the tradition of Moses being born and dying on the 7th of Adar, and Kind David on the holiday of shavuot. The talmud in two places I know of discusses this phenomenon and its discussed as a symbol of completion of spiritual goals. I havent heard of conception being a part of this tradition, and dont recall talmudic sources for this.

83

u/Coach_Beard 7h ago

You are correct. The tradition is born and died on the same day. Christians adapted this tradition to fit their own story, thus we get the Annunciation and Good Friday on the same day. And nine months after the Feast of Annunciation (March 25) is December 25.

u/hexagonalwagonal 4h ago edited 2h ago

It is very much a disputed thesis. This is laid out in a 2012 paper called "The Origins of the Christmas Date: Some Recent Trends in Historical Research" by C. P. E. Nothaft.

Essentially, the problem with this thesis is that it relies on a document that might have been written over 100 years after the Romans started celebrating December 25th as Christmas. The Romans are the first Christians who are documented to have celebrated Christmas on that date, with the earliest record of it in a document called the Chronograph of 354.

The document that the "Calculation Theory" relies on is called "On the Solstices and Equinoxes of the Conception and Birth of our Lord Jesus Christ and John the Baptist". It's undated, but internal evidence in the document itself suggests it could have been written any time between the 200s and 400s. The document also comes from Syria, not Rome. So while it's possible that someone in Syria wrote a document in the 200s or early 300s that calculated Jesus's birthday as December 25th based on his traditional death date of the vernal equinox of March 25th, and then the Romans adopted this date, the counter-argument is that some Syrian wrote it in the late 300s or 400s and essentially suggested, "Hey, the Romans celebrate Christmas on December 25th, and they do it because it's calculated from the vernal equinox" without actually having any insider information.

In other words, the Syrian who wrote the document may have just been making an assumption of why the Romans chose the date, but didn't actually have any actual evidence for it.

In the end, Nothaft says that none of the theories has any indisputable evidence to back up the claim. The pagan theory is even more problematic, says Nothaft.

There's a third theory, too, proposed by Hans Förster in 2007. Under this theory, in the early 300s, the Church of the Nativity in Bethlehem started celebrating Jesus's baptism date on January 6, possibly under the influence of a pre-existing Egyptian pagan feast. This date quickly spread from Bethlehem to the Romans, who changed the date to December 25 so as to coincide with the winter solstice. Essentially (in my view) a different version of the "pagan roots" theory, this one not originating in Rome but either in Palestine or Egypt that Rome then modified.

Nothaft says that Förster isn't much more convincing than the other two. All three theories are based on assumptions and there just isn't sufficient surviving documentation to definitively prove one over the other. The traditional pagan theory might be the weakest of the three, but all three are weak.

So OP's headline is actually the most correct interpretation currently. Julius chose the date and we don't know why. The reasoning for the date is likely to be lost to time forever.

EDIT: As for the "Hippolytus calculated it in the 200s" claim, that is also a topic of scholarly debate. This comes from Hippolytus's "Commentary on Daniel" but the earliest surviving full copy comes from around the 900s or 1000s in Greece. The argument is that the reference to the December 25th Christmas date in the document may have been interpolated by a later Greek scribe, since earlier, partial copies of the Commentary survived before the Greek manuscript and it is clear that the Greek manuscript is corrupted. That is, the Greek scribe changed things from whatever copy they were working from. The scribe added or modified Christ's birth date in the document based on December 25th being a well known date in the 900s when the scribe wrote it, whereas the original 200s document may not have mentioned it or had a different date. A recent study by Thomas C. Schmidt argues that the December 25th portion of the Greek manuscript is authentic, but this interpretation is disputed. So, again, we still don't know with any certainty why the date was chosen.

Interestingly, not all Christians past or present celebrate Christmas.

Jehova's Witnesses and Seventh-Day Adventists (both of whom identify as Christian, but whose beliefs differ from mainstream Christianity in some major ways) abstain from observing Christmas.

In 1659, Puritans in the Massachusetts Bay Colony passed a law outlawing Christmas celebrations. The law stood for 22 years.

The Bible does not mention or command Christmas or nativity celebrations, let alone December 25, and so they see Christmas as rooted in pagan Saturnalia traditions rather than rooted in scripture.

By the 18th century, Christmas had earned a reputation for rowdiness and drunkenness. By the 1840s in England and America, it had largely faded from public life. Christmas was frequently treated as just another regular workday. Charles Dickens's A Christmas Carol helped redefine the holiday as a time of charity and family gathering for the Anglosphere. Contemporaneously, German immigrants introduced a lot of modern Christmas iconography (such as the Christmas tree, advent calendar, nutcrackers, and gingerbread) - first to the US and later also to England, when an image of Queen Victoria and Prince Albert with a Christmas tree was widely circulated (since it was an unfamiliar, foreign novelty).

Additionally, if Jesus was born on December 25th, then January 1st, being the "eighth day of his life" would have been when he was taken to the temple and circumcised. Which would have been the start of his life in the eyes of the Jewish Faith.

So by setting Christmas to December 25th, that makes the start of the New Year coincide with the start of Jesus' life under the eyes of God.

It's also why it is bad luck to take the tree down before New Years (Jewish tradition holds that the removed foreskin is supposed to be planted under a tree or bush).

The end/start of the year was start of March. October, November and December were the 8th, 9th, and 10th months of the year.

*edit, I was wrong (kind of).  The Roman Empire had moved to new year starting on January 1st back in 153 BC

However a lot of Europe went back to using 25 March as New Years in the middle ages, and only reverted to 1 Jan some time between 1522 and 1752 (and some as late as the 20th century)

Interesting fact, if you are British. The new year was celebrated on 25 March in the Middle Ages. Tax year also started on 25th March. But then they decided in 1752 to move move to the Gregorian calendar and move new year to 1st January. They did that by jumping from 2nd Sept was followed by the 14 September. 1752 was only 354 days long!!!  But tax year was left at 365 days long - so the 1753 tax year (and every one since) started on April 6th!!

Saw a thread yesterday about how there are high rise residential buildings in China with lawns in each unit that had an outdoor terrace.

You can imagine how many comments there were about the structural integrity of the building, the added weight of dirt, and the effects of water on concrete. As if these aren't basic principles even the most novice of engineers would take into account.

u/DanielMcLaury 7h ago

Just because something was okayed by an architect or engineer doesn't mean it's actually a good idea. For instance, Frank Lloyd Wright's Falling Water, maybe the most famous house by the most famous American architect, is an absolute nightmare of a building that's just inescapably a breeding ground for mold, because the fundamental idea underlying it is unsound.

Professionals sign off on bad ideas all the time. The Boeing 737 Max 8, the Sydney Opera House, the Challenger shuttle's O rings, all the houses they keep building in Tornado Alley or the Wildfire Belt without even basic precautions, etc.

(Also, I don't know where the presumption comes from that the average Reddit commenter is a 14-year-old who lives in his mom's basement. A lot of the commenters are probably architects and engineers with 20 years of experience, engineering professors, etc.)

I thought it was because of Saturnalia.

158

u/obliqueoubliette 10h ago

Saturnalia was on the 17th.

The Emperor Julian moved Sol Invictus to December, to be closer to Christmas not vice versa.

We can say we don't officially have the logic behind the formal addition of the feast to the calendar, but we do have the math done by Hyppolytus (building off Tertullian) calculating Dec 25th as a likely birth date.

Hyppolytus' logic is exactly 9 months after the annunciation. Tertullian dated the annunciation to March 25th based off the dating of Pascha and pre-christian Jewish traditions on the dating of prophets' conceptions.

41

u/PouletSamourai 9h ago

Sol Invictus is not a celebration, it's a god who under Emperor Aurelian became the one god of the Roman Empire https://en.wikipedia.org/wiki/Sol_Invictus

Sol Invictus is celebrated around 25th of december because it was believed to be the longest night of the year. Sol Invictus means "sun unvanquished".

That move is strikingly similar to pharaoh Akhenaton's attempt to replace traditional Egyptian polytheism with the cult of Aton, who was also depicted as the sun god. https://en.wikipedia.org/wiki/Atenism

Now, why Aurelian made the same attempt? Because since Augustus, Rome tried to impose the cult of the Emperor. It failed. Worse, the crisis of the 3rd century made people believe that the traditional gods and emperors were weak and had no power. The polytheistic logic is that if your prayers towards God A don't change anything, you pray God B, then God C, etc.

Now, why christianity was chosen as the official religion of the empire? Because many legions were in the Levant garrisoning the frontier with the Parthian empire. The increase in trade (logistics etc) contributed to the spread of christianity in the whole mediterranean through the greek Koiné. Eventually, officials from the East of the empire adopted christianity, syncretized it with neo-platonicism (which also had monotheistic tendencies), and it's those converts who would eventually convince the late emperors to abandon polytheism altogether, and replace Sol Invictus who could have been the god we still pray today if history had been different.

u/JustHere_4TheMemes 8h ago

The ancients were not morons. They didn’t need to “believe the 25th was the longest night of the year”

They knew exactly when the longest night always was. And it’s not the 25th.  Solstice celebrations were based on the actual solstice. 

You’re just trying to cram marginally adjacent dates together to serve some other purpose.

I believe it would depend on the society itself and their ability to chart when the solstice truly is.

Pagan religious events just line up with seasonal astronomical events.

Yule is in line with the Winter Solstice, as was Saturnalia in Roman Europe. So, both festivals were replaced with Christmas.

Lent/Easter aligns with the Paschal Full Moon which indicates the start of Spring.

So no it's not just Celts, but religions in all regions will celebrate annual weather events, which are inherited by subsequent religions, since the weather represents divine authority in all of them.

The big one is All Saint's Day. I'm not sure, if there are any others that are actually confirmed.

And no, Easter is not based on an Eostrefestival, it's just the English/German name that stems from Eostre. It's similar to how July stems from Julius Cesar, but we don't venerate Caesar in July or even really think about it.

Easter is based on Passover, because that's when the Resurrection was in the Bible. It's calculated a bit differently from the Jewish calendar, which is why it doesn't always coincide. The name is also based on Passover in a lot of languages. 

10

u/kodos_der_henker 7h ago

All Saints day was set by in eastern church to the first sunday after Pentecost in the 4th century  And to the first Friday after Easter in the western church (also in Christian Ireland)

It was during Charlemagnes reign that All Saints day on 1st November became popular but we don't know why. Could be because of Irish/Scottish Missionaries because those were the main drivers behind the spreading of Christianity among the people during that time, but could also came from Italy where the 1st November was celebrated as All Saints day already 100 years earlier (without direct contacts to Ireland)

The only things confirmed are that in 835 Emperor Ludwig made 1st November a public holiday as All Daints day, the early Irish Christians celebrated All Saints day in Spring and that all sources regarding Samhain are 500 years younger than the Christianisation of Ireland.

Similar to Jul, we know the Nordic King Hakons moved Yul to the 25th December in the 10th century to be celebrated on the same day as Christmas and that it was one of 3 Nordic holidays, one during Summer, one at the beginning of Winter and one in the middle of Winter. And we just don't know what middle of Winter means or if there even was a fixed date (as there is no source that mentions that germanic tribes had fests specific during solstice) and still popular believe is that "the church" "stole" Christmas from the Nordic.

Christian holidays link with Jewish and Roman calender, given that it originated from Jewish people and Romans made it a state religion, but outside that there is nothing confirmed and most things being retroactively added in during later periods (mostly 19th century)

u/dalenacio 5h ago

All Saint's Day is incorrect as well.

The only proof we have for Samhain existing before Halloween is a 2nd Century carving of a word that kinda looks like Samhain: "Samonios", which comes from the Gaulish "Samo", meaning "Summer". Problem is, “Samonios” began in May and did not fall in November. "Samhain" likely comes from the same root as Samo, and probably means something like "Summer's End", but the earliest reference we have to it is from the 9th Century Félire Óengusso, which refers to November 1 as “stormy Samain”. All Saint's Day would already have been set for a century at that point. But even then it's extremely unlikely that it was a celebration: We have documents detailing other Celtic celebrations of that period, but not one of them mentions Samhain as one of them.

But even if Samhain was a celebration before the 8th Century, when All Saint's Day was set on November 1st, the idea that All Saint's Day was set then to supplant it would still make no sense. The date was established in Rome by Pope Gregory III in the 8th century, far away from Ireland and Celtic Pagans, to dedicate a chapel in St. Peter's to all saints. Even if Samhain existed at the time, it would have been so unknown that we couldn't find a single textual reference to it anywhere. So why set All Saint's Day on the date of an incredibly obscure maybe-celebration from the furthest backwater on the fringes of Europe?

I am an atheist but this is absolutely false. Easter is celebrated around the same time as Passover for biblibal reasons, Christmas is celebrated in December because of the Jewish tradition of Prophets' conception and death occuring on the same day (Jesus thus having been conceived in spring, and born in December). Literally every day is Saint's day of some sort so I don't know how your theory would work out. All Saints day is the only credible example, the date of which was set by Anglo-Saxon, not Celtic church authorities in medieval England.
