Few passages in the Bible have generated as much debate as Revelation 20. John describes Satan being bound for “a thousand years,” Christ reigning with His saints, and then Satan being released for “a little season” before his final defeat.
But what if those 1,000 years have already passed?
A controversial interpretation circulating today proposes a remarkable timeline:
AD 66 → AD 1066 = 1,000 years
According to this theory, the Millennium began around AD 66, and Satan's release occurred around AD 1066.
But there is another fascinating question:
If this interpretation is correct, when did Jesus return?
The answer depends on which version of the theory one follows.
1. What Does Revelation 20 Actually Say?
Revelation 20 describes four major events:
Satan is bound.
The saints reign with Christ for 1,000 years.
Satan is released for a short period.
Satan deceives the nations, leading to a final rebellion, followed by his ultimate judgment.
Revelation 20:2–3 describes Satan being confined, while verses 7–10 describe his release and the gathering of Gog and Magog.
The fascinating part is that Scripture explicitly gives us the number 1,000 years—but it does not explicitly give us a calendar date such as AD 66 or AD 1066.
That distinction is extremely important.
2. Why AD 66?
The year AD 66 is significant because it marks the beginning of the major Jewish revolt against Rome that eventually culminated in the destruction of Jerusalem and the Temple in AD 70.
Some full-preterist interpreters argue that the prophecies Jesus gave concerning His coming, judgment, and the end of the Jewish age were fulfilled in the events surrounding the Roman destruction of Jerusalem.
There are even interpreters who place Christ's prophetic “coming” specifically around AD 66, rather than AD 70. This is a minority position even within preterism.
Other preterists place Christ's coming in AD 70, when Jerusalem and the Temple were destroyed.
So we already have an important distinction:
Traditional Christian interpretation: Christ's Second Coming is still future.
Partial preterism: some major prophetic passages were fulfilled in the first century, while Christ's final return remains future.
Full preterism: essentially all major end-time prophecies, including Christ's coming, are understood as having been fulfilled in the first century.
And then there is this particular AD 66 → AD 1066 theory, which combines a first-century fulfillment framework with a proposed historical Millennium.
3. The Mathematical Argument: 66 + 1,000 = 1066
This is where the theory becomes intriguing.
If the Millennium began in AD 66, then:
AD 66 + 1,000 years = AD 1066
And therefore, according to the theory:
AD 1066 marks the end of the 1,000-year reign and the beginning of Satan's “little season.”
This is precisely the claim reflected in the image you shared.
But there's an important qualification:
The mathematics is straightforward; the biblical identification of AD 66 as the starting point is not.
Revelation doesn't say:
“The thousand years will begin in AD 66.”
That conclusion has to be constructed by connecting Revelation with other prophetic passages and historical events.
4. So When Did Jesus Come Back According to This Theory?
This is where things become particularly interesting.
There isn't one universally agreed answer even among preterists.
View 1: Jesus “came” in AD 70
Many preterists understand Jesus' coming as a judgment coming against Jerusalem.
In this interpretation, Christ did not necessarily descend physically from heaven in a visible bodily appearance.
Instead, the Roman armies became instruments of divine judgment against Jerusalem.
This interpretation connects Jesus' Olivet Discourse with the destruction of Jerusalem in AD 70.
Under this framework:
AD 70 = Christ's coming in judgment
rather than a future Second Coming visible to the entire world.
5. View 2: Jesus Returned Around AD 66
The more radical version of the theory shown in your screenshot goes further.
Some interpreters argue that Christ's prophetic return occurred around AD 66, at the beginning of the Jewish-Roman War.
One modern exposition explicitly argues that Jesus' coming and reign began around AD 66 and connects that date with the beginning of the thousand-year period ending in AD 1066.
The proposed sequence looks roughly like this:
AD 66
↓
Christ's prophetic coming
↓
Satan is bound
↓
The saints reign with Christ
↓
The Millennium
↓
AD 1066
↓
Satan is released
↓
“Satan's little season”
This is a very different chronology from the futurist model most Christians are familiar with.
6. But There Is a Major Problem With the Theory
And this is where we need to slow down.
Revelation 19 and 20 appear to present a sequence in which Christ's victory is followed by the Millennium, after which Satan is released. Many traditional interpreters therefore place Christ's return before the Millennium.
But if someone says:
Jesus returned in AD 66
and simultaneously says:
The Millennium began in AD 66
then they are effectively placing Christ's return at the beginning of the Millennium.
That can be internally consistent within a particular interpretation, but it requires a specific understanding of Revelation's chronology.
Furthermore, the nature of Christ's “return” becomes critical.
Did Jesus literally return bodily to earth?
Or does “coming” refer to divine judgment?
That is one of the biggest theological questions separating preterist and futurist interpretations.
7. What Happened in AD 70?
Regardless of which date one chooses, AD 70 is extremely important.
The Romans destroyed Jerusalem and the Second Temple.
For preterists, this event has enormous prophetic significance.
Jesus had warned:
“Not one stone here will be left on another.”
The destruction of Jerusalem therefore becomes a major candidate for the fulfillment of Jesus' prophecy concerning the coming judgment.
Preterists argue that the language of Christ “coming on the clouds” should be understood through the Old Testament prophetic tradition, where God is sometimes described as “coming” in judgment through historical events and earthly rulers.
That interpretation is controversial, but it provides the theological foundation for the idea that Christ's coming could have been fulfilled without a literal physical descent from heaven.
8. Then What Happened in 1066?
Now we reach the most fascinating historical connection.
1066 was a major turning point in European history.
William, Duke of Normandy, invaded England and defeated King Harold II at the Battle of Hastings.
The Norman conquest dramatically transformed England's political, cultural and religious landscape.
There was also an extraordinary celestial phenomenon associated with the year.
Halley's Comet appeared in 1066 and was depicted in the famous Bayeux Tapestry. Historical sources note its striking appearance and its association with the events surrounding the Norman conquest.
This has encouraged some prophetic interpreters to see 1066 as a possible symbolic turning point.
But we must be careful:
The appearance of Halley's Comet does not prove Revelation 20 was fulfilled in 1066.
And neither does the Norman conquest.
Those are historical correlations, not biblical proof.
9. Was Satan Actually Released in 1066?
This is the biggest claim.
Revelation 20:7–8 says that after the thousand years:
Satan is released.
He then goes out to deceive the nations and gathers Gog and Magog for battle.
If the AD 66–1066 theory is correct, then something extraordinary should have happened around 1066 that corresponds to this prophetic description.
And this is where the theory becomes much harder to establish.
Wars, political upheavals, religious conflicts, invasions and persecution certainly occurred after 1066.
But those things also occurred before 1066.
Therefore, simply saying:
“There was enormous conflict after 1066, therefore Satan was released” doesn't establish the prophecy.
The historical evidence needs to demonstrate a much stronger correspondence.
10. Could “Satan's Little Season” Be the Period After 1066?
This is an intriguing possibility within the theory.
If Satan was released in 1066, then the world after 1066 could theoretically represent the “little season.”
That would mean the period in which we currently live could potentially be interpreted as the continuation of Satan's deception.
Some non-futurist interpretations understand Satan's “little season” as a period of intensified opposition to the church immediately before final judgment.
But there is an enormous chronological problem:
We are now approximately 960 years beyond 1066.
If “little season” means a short period relative to the Millennium, why has it lasted almost a millennium?
That doesn't automatically disprove the interpretation, because prophetic time expressions can be symbolic.
But it creates a serious question that proponents of the 1066 theory must answer.
11. What About the “Thousand Years” Being Symbolic?
There is another possibility.
Perhaps the number 1,000 isn't intended as a literal 1,000 solar years.
Christian interpreters have historically disagreed about this.
Some understand the Millennium literally.
Others understand “1,000 years” symbolically as representing a long, complete period.
Amillennial interpretations, for example, understand the Millennium as the present reign of Christ rather than a literal future thousand-year earthly kingdom.
Therefore:
66 → 1066
is only compelling if the number is understood literally and AD 66 is correctly identified as the starting point.
12. Three Possible Timelines
It's useful to put the major interpretations side by side.
FUTURIST VIEW
Christ's first coming
↓
Church age
↓
Future tribulation
↓
Future Second Coming
↓
Millennial Kingdom
↓
Satan released
↓
Final judgment
This remains one of the major traditional interpretations.
PRETERIST AD 70 VIEW
Christ's first coming
↓
Church age / first-century prophetic fulfillment
↓
AD 70 — Christ's coming in judgment
↓
Destruction of Jerusalem and Temple
↓
The Jewish age ends
↓
Christ's kingdom continues
This is broadly representative of the preterist understanding, although individual preterists differ significantly.
AD 66 → 1066 THEORY
AD 66
Christ's prophetic coming/reign begins
↓
Satan bound
↓
1,000-year Millennium
↓
AD 1066
Satan released
↓
“Satan's little season”
↓
Final judgment
This is the particularly controversial interpretation represented by the post you shared.
13. The Biggest Question: Are We Living in Satan's Little Season?
This is where the theory becomes genuinely provocative.
Look around the world.
Wars.
Political instability.
Persecution.
Moral confusion.
Religious deception.
Ideological extremism.
Technological manipulation.
Increasing distrust.
Division among nations.
Could this be what Revelation means by Satan being released to deceive the nations?
It is certainly possible to draw parallels.
But parallels are not proof.
Human history has experienced enormous periods of violence and deception throughout the last 2,000 years.
Therefore, we should not say:
“Current events prove Satan was released in 1066.”
The Bible doesn't give us enough information to make that declaration with confidence.
14. The Most Important Biblical Question
Perhaps the most important question isn't:
“Was Satan released in 1066?”
It is:
“What did Jesus mean when He said He would come?”
Jesus repeatedly spoke about His coming.
For example, Matthew 24 contains His famous Olivet Discourse.
Some Christians understand those statements primarily as referring to the future Second Coming.
Preterists argue that much of the discourse concerned the coming judgment upon Jerusalem in the first century.
That debate is fundamental to understanding the entire timeline.
15. So, When Did Jesus Come Back?
If we are specifically asking:
“According to the interpretation behind this AD 66–1066 theory, when did Jesus come back?”
The answer would generally be:
Around AD 66, according to the more extreme version of the theory.
Some other preterists would instead say:
AD 70, particularly in connection with the destruction of Jerusalem.
But neither date represents the consensus of Christianity.
And even among preterists, the meaning of “return” varies.
Some mean a real but invisible/parousia-type judgment presence, rather than Jesus physically appearing on earth.
That distinction is essential.
16. Does the Bible Actually Say Jesus Returned in AD 66?
No.
There is no verse saying:
“Jesus will return in AD 66.”
Likewise, there is no verse saying:
“Satan will be released in AD 1066.”
Those dates are interpretive conclusions created by connecting biblical prophecy with historical chronology.
That's why we should present this as a theory, not as a biblical fact.
Even scholarly commentary on Revelation emphasizes that the Millennium is one of the most difficult and disputed prophetic subjects in the New Testament.
17. A Fascinating Possibility—or a Dangerous Overreach?
The AD 66 → 1066 theory deserves examination because it raises fascinating questions:
Why AD 66?
Why 1,000 years?
Why 1066?
What happened historically in 1066?
What does “Satan's little season” mean?
Was Jesus' coming in AD 70 a judgment coming?
Could Revelation's chronology have already unfolded?
These are legitimate questions for Bible study.
But we should resist the temptation to force history into prophecy simply because two dates line up mathematically.
18. Final Conclusion
The claim that the Millennium lasted from AD 66 to AD 1066 is a fascinating but highly controversial interpretation of Revelation 20.
According to the strongest form of this theory:
AD 66 — Christ's prophetic return and beginning of His reign
AD 66–1066 — the 1,000-year Millennium
AD 1066 — Satan released
After 1066 — Satan's “little season”
Future/ultimate conclusion — final judgment and Satan's destruction
However, this chronology is not explicitly stated in Scripture.
The AD 66 date for Christ's return is particularly associated with a minority preterist interpretation; many preterists instead place the significant “coming” in AD 70, while futurists expect Christ's bodily Second Coming in the future.
So perhaps the most responsible conclusion is:
1066 may be an intriguing historical date to investigate, but we should not turn an interpretive theory into a certainty that the Bible itself does not explicitly establish.
And that makes the subject even more fascinating.
Was 1066 the beginning of Satan's little season—or merely a remarkable coincidence?
That is a question worth opening the Bible and history books to investigate.
