A close friend of mine, a cryptographer, recently published a Kindle book on
Amazon, "Rapture 2021" by Gerald Eastwood
It details how mathematically, through triangulation, that the final months of 2021 are the months for the Rapture and that is followed by the Gog-Magog War, after the Rapture (about a month later in early December). There is a lot of historical data that proves Jesus died in AD 28. It’s interesting that 2,000 years from AD 28 is 2028, and if you subtract the 7 years of the Tribulation you are right here right now. There’s a slight shortening of the 7 years by just under five months, and that means we are currently in a very small space of grace, right before the end. The Rapture may well happen on a “day we think not” per Jesus, so it’s non-paradigm thinking to reasonably consider non-Feast Days. Eastwood says a lot of the math culminates around October 31st and November 1st, with a “half hour of silence” following the Rapture leading to the Ezekiel Gog-Magog Battle (WW III) in early December, again on a specific set of days that are not part of the major Jewish Feasts but a minor one.
