Quick Answer: Discover what the Bible says about those who attempt to calculate Jesus’ return, the meaning of Matthew 24:36, and why scripture emphasizes spiritual readiness.
When the world feels chaotic—when headlines are dominated by wars, pandemics, economic instability, and natural disasters—it is profoundly human to look to the horizon and ask, “How much longer— In times of acute suffering or profound cultural shifts, believers throughout history have eagerly turned to the Scriptures, hoping to find a timeline, a hidden code, or a way to calculate Jesus’ return. We crave certainty in an uncertain world. The desire to know when Jesus Christ will return is not usually born of mere intellectual curiosity; it is often birthed from a deep, groaning desire for justice, peace, and the restoration of all things.
Yet, this earnest desire has sometimes led well-meaning Christians down a dangerous path. Throughout church history, from the Millerite movement in the 1840s (which led to the “Great Disappointment”) to modern prognosticators who set dates based on blood moons, political elections, or obscure mathematical formulas, the result is always the same: missed deadlines, disillusioned followers, and a watching world that mocks the Christian hope. The practice of date-setting inevitably damages the witness of the Church and distracts believers from their primary calling.
So, can the date of Jesus’ return be calculated? The biblical answer is an emphatic, unequivocal “no.” However, the Bible does not leave us in the dark. Instead of a calendar date, Scripture gives us something far more profound: a theological framework for living in the “already but not yet” tension of the Kingdom of God, and a mandate to live with vigilant, joyful expectation. Let us dive deep into the Scriptures to understand why the date cannot be known, what the biblical original languages reveal about God’s timing, and how we are meant to live in light of this truth.
A Pastoral Note: I remember a season when a popular book had many in our congregation anxiously charting out end-times timelines and stockpiling supplies. It broke my heart to see so much fear and distraction replace the joyful anticipation of Christ’s return. In pastoral counseling, I’ve found that trying to decode prophecies often masks a deeper anxiety about losing control of our futures. Jesus called us to be ready and faithful in our daily lives, not to abandon our present responsibilities to become prophecy obsessives.
The Clear Biblical Answer: No One Knows the Day or Hour
When addressing the end of the age, Jesus was remarkably clear about the limitations of human (and even angelic) knowledge regarding the timing of His return (often called the Parousia, a Greek word meaning “presence” or “arrival”).
The Words of Jesus Himself
The most definitive statement on this topic comes directly from the mouth of Christ in the Olivet Discourse:
“But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.” (Matthew 24:36, KJV)
In the original Greek, the word for “knoweth” is oida, which means to have inherent, absolute knowledge, to perceive or understand completely. Jesus is stating that this specific knowledge is exclusively reserved for the Father. The phrasing “day and hour” is a common Jewish idiom for an exact time. Some modern date-setters have attempted to circumvent this by claiming, “We cannot know the day or the hour, but we can know the month or the year!” This is a gross mishandling of the text and ignores the immediate context, where Jesus is illustrating total unpredictability, comparing His return to the sudden, unexpected flood in the days of Noah (Matthew 24:37-39).
Furthermore, just moments before His ascension, the disciples asked Jesus, “Lord, wilt thou at this time restore again the kingdom to Israel— (Acts 1:6). Notice Jesus’ gentle but firm rebuke:
“And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power.” (Acts 1:7, KJV)
Here, the Greek text uses two distinct words for time: chronos (chronological time, periods, or durations) and kairos (epochs, strategic seasons, or appointed times). Jesus comprehensively shuts the door on all forms of date-setting. It is not for us to know the chronos (the exact date or year) nor the kairos (the general prophetic season calculated on a calendar). The Father has placed this entirely within His own sovereign authority (exousia).
Why Do People Keep Trying to Calculate It?
If the biblical mandate is so clear, why do books predicting the end times continue to become bestsellers? The answer lies in a combination of human anxiety, the misinterpretation of biblical prophecy, and a misunderstanding of what Jesus meant by the “signs of the times.”
The Misunderstanding of “Signs of the Times”
Jesus did instruct His followers to be aware of the spiritual climate. In Matthew 24, He speaks of “birth pangs”—wars, famines, and earthquakes. He also uses the analogy of a fig tree:
“Now learn a parable of the fig tree; When his branch is yet tender, and putteth forth leaves, ye know that summer is nigh: So likewise ye, when ye shall see all these things, know that it is near, even at the doors.” (Matthew 24:32-33, KJV)
Many read this and assume Jesus is giving us puzzle pieces to assemble into a timeline. However, “signs” in biblical prophecy are rarely meant to serve as a countdown clock. Instead, they are meant to serve as moral and spiritual wake-up calls. The “birth pangs” remind us that the current world system is passing away and that we must remain faithful. Recognizing that “summer is nigh” is a call to readiness, not a call to calculation.
The Misuse of Daniel and Revelation
Much of Christian date-setting originates from misapplying the apocalyptic literature found in Daniel and Revelation. Apocalyptic literature is a highly symbolic genre designed to reveal spiritual realities and the ultimate triumph of God over evil.
For instance, people attempt to take Daniel’s “seventy weeks” (Daniel 9:24-27) or the “time, times, and half a time” (Daniel 12:7), or the 1,260 days in Revelation (Revelation 11:3, 12:6), and map them onto the modern Gregorian calendar. But ancient Jewish apocalyptic numbers are primarily theological, not strictly chronological. Numbers like 7 (perfection), 12 (God’s people), and 1,000 (a vast, complete amount) are used to convey deep truths about God’s sovereignty and the ultimate victory of the Lamb, Jesus Christ. Attempting to use them as a divine decoder ring for the 21st century strips them of their original theological majesty and turns God’s grand redemptive narrative into a cheap parlor trick.
The Theological Purpose of Unknown Timing
God does not hide the date of Jesus’ return to frustrate us. There is a profound, life-giving theological purpose behind this mystery. The unknown timing is a deliberate design of God’s grace to cultivate specific virtues in the life of the believer.
Cultivating Vigilance and Readiness
The primary application Jesus draws from the unknown timing of His return is the necessity of constant vigilance. The Greek word repeatedly used in the New Testament is grēgoreō, meaning to stay awake, to watch, to be vigilant and alert.
Consider the Parable of the Ten Virgins (Matthew 25:1-13). The bridegroom was delayed, and all ten virgins fell asleep. The difference between the wise and the foolish was not that the wise had calculated the bridegroom’s arrival time; the difference was that the wise had oil in their lamps. They were prepared for a delay.
“Watch therefore, for ye know neither the day nor the hour wherein the Son of man cometh.” (Matthew 25:13, KJV)
If we knew the exact date of Christ’s return, human nature dictates that we would either procrastinate in our spiritual walk, living in sin until the final moment, or we would be paralyzed by terror and anxiety as the date approached. Just as believers often wonder do we have free will in heaven, we must exercise our free will here on earth by walking closely with God every single day and maintaining a posture of perpetual readiness.
Encouraging Faith Over Sight
The Christian life is defined by walking by faith, not by sight (2 Corinthians 5:7). If we possessed an exact timeline, faith would be replaced by calculation. The mystery of the Parousia forces us to trust in the character of God—just as we must when exploring mysteries like is God male or female in the Bible—rather than in our own intellectual ability to decipher a timeline. It shifts our focus from the timeline to the Person of Jesus Christ.
The Beautiful Patience of God
Perhaps the most comforting reason for the delay of Christ’s return, and the mystery surrounding it, is found in the heart of God for the lost. In the first century, some believers were already beginning to scoff and ask why Jesus hadn’t returned yet. The Apostle Peter responds:
“The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.” (2 Peter 3:9, KJV)
The Greek word for longsuffering is makrothumeō, which literally means “long-tempered” or passionately patient. The reason we cannot calculate the date is because the calendar is currently dictated by the mercy of God. Every day that Christ delays is another day of grace, another opportunity for the gospel to be preached, and another chance for prodigals to come home.
Addressing Common Objections and Misconceptions
Despite the clear biblical evidence, some still argue that true, spiritual Christians can know the timing. It is vital to address these misconceptions gracefully but firmly.
Objection 1: “We might not know the day or hour, but we can know the year or month.”
As addressed earlier, this objection slices the words of Jesus far too thinly. When Jesus said no one knows the “day or hour,” He was employing a figure of speech known as a merism, where two contrasting or related parts are used to express totality (like saying “I searched high and low,” meaning everywhere). Jesus means we do not know the timing at all. Furthermore, Acts 1:7 explicitly rules out knowing the broader “times or seasons” (chronos and kairos).
Objection 2: “1 Thessalonians 5 says we are not in darkness that the day should surprise us.”
Those who advocate for calculating the end times frequently cite the Apostle Paul:
“But ye, brethren, are not in darkness, that that day should overtake you as a thief. Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness.” (1 Thessalonians 5:4-5, KJV)
Does this mean believers will figure out the date so they won’t be surprised? No. Paul is speaking about spiritual and moral readiness, not calendrical knowledge. Look at the context. Paul just stated in verse 2 that “the day of the Lord so cometh as a thief in the night.” A thief does not announce his arrival. The reason the Day will not “overtake” believers is because they are living in the light—living holy, obedient lives. If a thief breaks in while you are already awake and guarding your house, you are not overtaken, even though you didn’t know exactly when he would arrive. The preparation is continuous, not scheduled.
Objection 3: “God reveals His secrets to His prophets (Amos 3:7).”
Amos 3:7 states, “Surely the Lord GOD will do nothing, but he revealeth his secret unto his servants the prophets.” While true, this does not override the explicit teaching of Jesus. The prophets were given the revelation that Christ would return, the manner of His return, and the need for readiness. The New Testament is the ultimate prophetic revelation, and it clearly reveals that the specific timing is a secret God has chosen not to reveal (Deuteronomy 29:29).
3 Practical Applications
Since we cannot and should not calculate the date of Jesus’ return, how then shall we live? Eschatology (the study of end times) is never meant to merely fill our heads with charts and theories; it is meant to transform our hands, our feet, and our hearts.
1. Live in a State of Active, Not Passive, Readiness
Biblical waiting is not like waiting for a bus, sitting passively on a bench. Biblical waiting is like a waiter in a restaurant, actively serving and working until the shift is over. To “watch” (grēgoreō) means to be actively engaged in personal holiness. Examine your heart daily. Confess sin quickly. Cultivate the fruit of the Spirit. Live today as if it were the day of His return, embracing the role of the Holy Spirit in decision making and making choices that you would not be ashamed of if He were to appear this very hour.
2. Focus on the Great Commission, Not the Calendar
In Acts 1, immediately after Jesus tells the disciples that they cannot know the times or seasons, He gives them their mission: “But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me…” (Acts 1:8). The energy many Christians spend trying to decode the end times would be vastly better spent sharing the Gospel. If the delay of Christ’s return is due to God’s patience so that more may be saved (2 Peter 3:9), then our most “eschatological” act is to evangelize, disciple, and love our neighbors in the name of Jesus.
3. Find Deep Hope, Not Fear, in His Return
For the believer, the return of Jesus is not a terrifying doomsday; it is the “blessed hope” (Titus 2:13). The fact that we do not know the exact date should free us from anxiety. God is firmly in control of human history. The ending has already been written, and the victory is secure in the resurrection of Christ. Whenever that trumpet sounds—whether today, tomorrow, or a thousand years from now—it will be the moment when every tear is wiped away, death is swallowed up in victory, and we are finally and forever with our Lord. Therefore, comfort one another with these words.
