October 22, 1844.
The sanctuary explained.
A Bible study of the 2,300 days, the Day of Atonement, and Christ’s work in the most holy place, following The Great Controversy, chapters 18–28, with the gospel emphasis of Steps to Christ.
01 · Begin with Daniel 8 and 9
The prophecy and its explanation
“Unto two thousand and three hundred days; then shall the sanctuary be cleansed.”
Daniel 8:14 · KJVDaniel 8 gives the prophetic period. In Daniel 9, Gabriel returns to explain the vision and introduces the seventy weeks appointed to Daniel’s people and Jerusalem. The Great Controversy explains these seventy weeks as “cut off” from the 2,300 days: they form the first part of that longer period, with both periods beginning together.
In this symbolic prophecy, a day represents a year. Numbers 14:34 and Ezekiel 4:6 provide the day-for-a-year principle used in this explanation: 2,300 prophetic days represent 2,300 years.
Read the KJV: Daniel 8:14–27; Daniel 9:21–27; Numbers 14:34; Ezekiel 4:6.
EGW: The Great Controversy, 324.3; 325.1–326.2.
02 · Why the autumn of 457 B.C.?
The commandment to restore Jerusalem
Daniel 9:25 begins the period with the commandment to restore and build Jerusalem. Ezra 6:14 names Cyrus, Darius, and Artaxerxes. The Great Controversy explains that their successive actions brought the decree to completion, with its fullest form issued by Artaxerxes in 457 B.C.
Ezra 7:12–26 records this decree, including provision for worship and authority to appoint magistrates and judges. The decree took effect in the autumn of 457 B.C. That is the starting point used in the prophetic reckoning.
Read the KJV: Daniel 9:25; Ezra 6:14; Ezra 7:12–26.
EGW: The Great Controversy, 326.3–327.1.
For the autumn starting season, see The Great Controversy, 398.4.
03 · The seventy weeks point to Christ
His baptism, sacrifice, and the gospel invitation
Seventy weeks represent 490 years; the first sixty-nine weeks represent 483 years. The fulfillment centers on Jesus Christ. The chronology below follows the explanation in The Great Controversy.
| Prophetic milestone | Fulfillment |
|---|---|
| Autumn A.D. 27 · End of 69 weeks | Jesus is baptized and anointed by the Holy Spirit, 483 years after autumn 457 B.C. |
| Spring A.D. 31 · Middle of the final week | Jesus is crucified, three and a half years after His baptism. His sacrifice fulfills the offerings that pointed forward to Him. |
| A.D. 34 · End of 70 weeks | The 490 years end. Stephen’s martyrdom and the ensuing persecution mark the widening proclamation of the gospel beyond the Jewish nation. |
Read the KJV: Daniel 9:24–27; Luke 3:21–22; Acts 10:38; Mark 1:14–15; Matthew 27:50–51; Acts 7:54–8:5.
EGW: The Great Controversy, 410.1; 345.1–347.2.
04 · From the seventy weeks to 1844
One connected prophetic period
The 490 years are part of the 2,300 years. When the seventy weeks end in A.D. 34, 1,810 years remain. Adding those remaining years reaches A.D. 1844.
| Step | Reckoning |
|---|---|
| The full period | 2,300 years |
| The seventy weeks | 70 × 7 = 490 years |
| The remainder | 2,300 − 490 = 1,810 years |
| The ending year | A.D. 34 + 1,810 years = A.D. 1844 |
The starting season matters: reckoning from autumn 457 B.C. brings the period to autumn 1844. The calendar passes directly from 1 B.C. to A.D. 1, with no year zero.
05 · Why October 22?
The tenth day of the seventh month
The sanctuary service supplies the connection between the prophetic period and the appointed day. Leviticus places the annual Day of Atonement on the tenth day of the seventh month. The Great Controversy identifies that day in 1844 as October 22.
Chapter 22 explains how the Passover sacrifice and the wave sheaf pointed to Christ’s death and resurrection. The Day of Atonement likewise directs attention to the appointed time and work of cleansing the sanctuary.
| Biblical observance | Appointed time | KJV reference |
|---|---|---|
| Passover | Fourteenth day of the first month, at even. | Leviticus 23:5 |
| Feast of weeks / Pentecost | Fifty days counted from the wave-sheaf offering. | Leviticus 23:15–16 |
| Day of Atonement | Tenth day of the seventh month. | Leviticus 16:29–34; 23:27 |
The Bible gives the sanctuary observance and its day; The Great Controversy, 399.4, supplies the stated correspondence to October 22, 1844. These chapters do not provide a month-by-month reconstruction of the Karaite calendar.
Read the KJV: Leviticus 23:5, 15–16, 27, 32; Leviticus 16:29–34.
EGW: The Great Controversy, 399.1–399.4.
06 · What sanctuary was to be cleansed?
Christ’s ministry in heaven
Hebrews describes both the earthly sanctuary and the heavenly sanctuary where Jesus ministers for us. The earthly tabernacle was patterned after the heavenly. Its priests served daily, and the high priest performed the annual cleansing service in the most holy place.
At the close of the 2,300 years in 1844, Christ entered the most holy place of the heavenly sanctuary to begin the closing work of atonement. This was a change in His heavenly ministration. His priestly ministry had already begun after His ascension.
The cleansing concerns the removal of sin and the examination of the heavenly records. It includes the investigative judgment, which precedes Christ’s return. His once-for-all sacrifice is the basis of this ministry; He is not sacrificed again.
Read the KJV: Hebrews 8:1–5; Hebrews 9:6–7, 22–28; Daniel 7:9–10, 13–14.
EGW: The Great Controversy, 417.1–422.1; 352.2.
Christ is our Advocate in this judgment. He presents His merits on behalf of those who repent and trust in Him. The judgment begins with the dead and proceeds to the living; the time when the living are considered has not been revealed to us.
07 · Understanding the disappointment
The time and the event
The believers expected Jesus to return to earth in 1844. Their disappointment arose from identifying the cleansing of the sanctuary with the purification of the earth by fire. Further study of the sanctuary made the event clear.
“The mistake had not been in the reckoning of the prophetic periods, but in the event”
Ellen G. White · The Great Controversy, 424.1 · excerptDaniel 7:13 describes the Son of man coming to the Ancient of days. Chapter 24 connects this with Christ’s entrance into the most holy place, His coming to His temple in Malachi 3, and the Bridegroom’s coming to the marriage in Matthew 25.
Christ’s work in the most holy place began in 1844. His visible second coming remains future. Chapter 19 compares this disappointment with the disciples’ misunderstanding before the cross: the prophetic word was fulfilled while the expected event was misunderstood.
Read the KJV: Daniel 7:13–14; Malachi 3:1–3; Matthew 25:1–13.
EGW: The Great Controversy, 423.1–426.1; 351.1–352.3.
08 · The time of the end and the angels’ messages
The wider prophetic setting
The 1,260-year period provides the setting for the renewed study of prophecy. The Great Controversy identifies it as A.D. 538–1798, with the pope’s captivity by the French army marking its close. Since 1798, Daniel’s prophecies concerning the last days have been opened to increasing understanding.
This period establishes the setting; the 2,300 years and the sanctuary service supply the explanation of 1844. The first angel of Revelation 14 announces the judgment within the everlasting gospel. The second angel warns of Babylon’s fall. Chapter 21 explains that this warning began to be proclaimed in 1844, with its full fulfillment still ahead.
Read the KJV: Daniel 7:25; 12:4; Revelation 13:5, 10; Revelation 14:6–8.
EGW: The Great Controversy, 355.1–356.2; 389.2–390.2; 439.2.
09 · The sanctuary reveals our present duty
Faith in Jesus, obedience, and preparation
Revelation 11:19 shows the ark of God’s testament in His heavenly temple. Chapter 25 connects this with the ministry in the most holy place and the enduring authority of God’s law, including the seventh-day Sabbath.
The three angels’ messages call us to worship our Creator, keep His commandments, and hold the faith of Jesus. While Christ ministers for us, we are called to repentance, the putting away of sin, and a life transformed by His grace. Chapter 26 presents Sabbath reform as part of this work.
This study gives no new date for Christ’s return. The Great Controversy maintains the autumn 1844 conclusion of the 2,300 days and warns against setting further dates for the second advent. Our calling is to follow Christ by faith and share His message.
Read the KJV: Revelation 11:19; Revelation 14:6–12; Exodus 20:8–11; Isaiah 58:12–14.
EGW: The Great Controversy, 425.1; 433.1–435.2; 451.1–452.2; 456.1–457.1.
We do not earn acceptance with God by our works. We receive Christ by faith, and His righteousness stands in place of our failure. As we abide in Him, His Spirit renews the heart and brings forth obedience. Preparation for His return is a daily life of dependence on our Saviour.
EGW: Steps to Christ, 59–63; 68–72.
