The Grace Amadon Collection is a collection of material from the General Conference committee in the 1930s that were tasked with delving deeply into the biblical basis for how the Day of Atonement is to be calculated scientifically. Another point of the study was to settle beyond all scientific doubt that October 22, 1844 was the actual day of Atonement that year.
Both of those goals were met in this study, but somehow, even though the leading SDA theologians of the day (LeRoy Froom and M.L. Andreasen) were on the committee, and seemed to agree with the results, and even though this study took several years and quite a lot of money to produce, it was never released in a normal way to the church, but basically just shelved.
Be that as it may, what I have found available on the internet is a treasure trove of info for figuring out for yourself how to calculate the Day of Atonement (Yom Kippur), and of course all the Feasts of the Lord, each year.
This report shows that Jesus Christ was crucified on a Passover on Friday, April 27, 31AD, and went into the Most Holy Place on October 22, 1844. With these two time anchors, it becomes quite easy to determine when any of God’s holy feast days occurs. Personally, I believe we are to still keep them, as Jesus did, as he is our perfect example.
