Was The Day of Atonement In 1844 On October 22?

Question:

Is there a way to locate and utilize the most authoritative source to unequivocally and concisely demonstrate that the Day of Atonement in the year 1844 occurred precisely on the 22nd of October?

Answer:

For generations, the date October 22, 1844, has carried profound meaning among Advent believers. It represents the time when many concluded that Christ entered the final phase of His high-priestly ministry in the heavenly sanctuary. But how can we be sure that this was truly the Day of Atonement—the tenth day of the seventh month in the year 1844? Was this date arbitrary, or can it be demonstrated clearly and historically that October 22, 1844, was indeed that sacred day?

The Bible provides the foundation for identifying the Day of Atonement. In Leviticus 16:29 and 23:27, God appointed that this solemn day should occur “on the tenth day of this seventh month.” The Hebrew year was based on lunar months that began with the first visible new moon, while the first month of the year was determined when the barley in Israel reached the stage called abib (see Exodus 12:2; 13:4). Thus, to locate the Day of Atonement for any given year, one must determine when the tenth day of the seventh lunar month fell according to the proper calendar reckoning.

By the nineteenth century, two principal methods existed for determining the sacred festivals—the Rabbinic and the Karaite calendars. The Rabbinic Jewish calendar, long standardized, used fixed calculations rather than direct observation of the new moon or barley harvest. According to this system, the tenth day of the seventh month (10 Tishri 5605) fell on September 23, 1844, beginning at sundown the previous evening. Modern Jewish calendar reconstructions such as Hebcal confirm this date. However, the Karaite Jews rejected this fixed system, preferring to determine each month by the actual sighting of the new moon and the ripeness of the barley. This method often caused their feasts to fall one lunar month later than those observed by Rabbinic Jews.

Samuel S. Snow, a Millerite preacher, adopted this Karaite or “biblical” reckoning while studying Daniel 8:14—”Unto two thousand and three hundred days; then shall the sanctuary be cleansed.” He reasoned that the cleansing of the sanctuary typified the Day of Atonement and sought to determine its precise date in 1844. In August 1844, Snow published a paper titled The True Midnight Cry, in which he concluded—based on the Karaite calendar—that the tenth day of the seventh month in that year would fall on Tuesday, October 22, 1844. Importantly, this was not an after-the-fact invention; Snow’s calculation was publicly preached and printed weeks before the date arrived.

Snow’s reasoning was straightforward: the 2,300 prophetic years began with the decree to restore Jerusalem in 457 BC and would therefore end in AD 1844. The “cleansing of the sanctuary,” he argued, pointed to the antitypical Day of Atonement. According to the Karaite calendar, the tenth day of the seventh month in 1844 occurred on October 22, making it the day of prophetic fulfillment. This “seventh-month message” or “midnight cry” spread rapidly through Millerite gatherings and camp meetings, leading thousands to expect Christ’s return on that exact day. When the event did not occur, it became known as the Great Disappointment. Yet those who later formed the Seventh-day Adventist Church retained the conviction that the date itself was correct, understanding instead that the event took place in heaven—Christ beginning His final work of intercession rather than returning to earth.

When critics ask whether Jews in general observed the Day of Atonement on October 22, 1844, the honest answer is no. Mainstream Rabbinic Judaism observed Yom Kippur beginning at sundown September 22 and continuing through September 23. But the Adventist position is not based on the Rabbinic calendar—it rests on the Karaite or biblical method of reckoning time, which that year placed the tenth day of the seventh month on October 22. Contemporary evidence, including Snow’s True Midnight Cry and other Millerite publications, proves that this calculation was known, published, and accepted before the date occurred.

Thus, the question of “authority” depends on what one means by the term. If by “authoritative” we mean the calendar in general Jewish use, then September 23, 1844, was the Day of Atonement that year. But if by “authoritative” we mean the system adopted by those who sought to follow the ancient biblical model preserved among the Karaites—the method used by the Millerite preachers—then October 22, 1844, stands as the correct date. The authority behind October 22 rests not on later reinterpretation but on the contemporaneous reasoning of Samuel S. Snow, printed August 22, 1844, and based on a demonstrable calendar tradition distinct from Rabbinic computation.

In summary:

1. The Day of Atonement occurs on the tenth day of the seventh month (Leviticus 23:27).
2. The Rabbinic calendar placed that day in 1844 on September 23.
3. The Karaite observational calendar, using visible moons and barley readiness, placed it on October 22, 1844.
4. Samuel S. Snow, in The True Midnight Cry, publicly identified October 22 as the true Day of Atonement and the close of the 2,300-year prophecy.
5. The Advent believers accepted this conclusion, later affirming that Christ’s antitypical atonement began that day.

In the end, the claim that the Day of Atonement in 1844 fell on October 22 is not a post-hoc invention but a reasoned conclusion grounded in the Karaite or “biblical” calendar method. While mainstream Judaism observed Yom Kippur in September 1844, the Karaite system used by the Millerite Adventists identified October 22 as the true tenth day of the seventh month. On that date—according to their understanding—the heavenly work foretold in Daniel 8:14 began: “Then shall the sanctuary be cleansed.”
