It appears a foolish error was made in the previous models. A closer examination of the END DATE yields a more correct result.
Looking at the projected date for the Day of Atonement in 2028, we must first identify the correct dates for the New Moon. The New Moon dates for 2028 can be found here:
The first fall New Moon AFTER the fall equinox is actually October 18-19, 2028. This yields a date for the Day of Atonement of October 28-29, 2028. Per our model, we then would subtract 2550 days to yield the day for the Feast of Trumpets to begin in 2021. This yields a date of November 4-5, 2021. This is indeed a New Moon in 2021, which can be verified here:
The correct date for the beginning of the Final Jubilee would then be November 14-15, 2021. The Two Witnesses would then arrive on December 14-15, 2021. The midpoint, and Abomination of Desolation, would then occur 1260 days later on May 27-28, 2025. Adding a shortened 1250 days then brings us back to our concluding date for the Day of Atonement on October 28-29, 2028. Adding 75 days brings us to our date for the rededication of the defiled Temple (Hanukkah) on January 11-12, 2029.
Taking a look at the heavens on November 4-5, 2021 (via Stellarium) yields an interesting result:
This is of course speculation, but there is still hope that our understanding of the fig tree generation and the 80 years to completion of the prophecies remains correct.
