Agree, fall feasts will be fulfilled upon His second coming.
Do they factor in as for the timing - perhaps, but the most important factor to consider is Roman’s 11:25. When the fullness of gentiles has come in, a date at which only God can know, then the rapture happens
Romans 11:25
25 I do not want you to be ignorant of this mystery, brothers and sisters, so that you may not be conceited: Israel has experienced a hardening in part until the full number of the Gentiles has come in.
Fall feasts
5)
Trumpets (
Leviticus 23:24) – The first of the fall feasts. Many believe this day points to the Rapture of the Church when the Messiah Jesus will appear in the heavens as He comes for His bride, the Church. The Rapture is always associated in Scripture with the blowing of a loud trumpet (
1 Thessalonians 4:13-18 and
1 Corinthians 15:52).h h
6)
Day of Atonement (
Leviticus 23:27) – Many believe this prophetically points to the day of the Second Coming of Jesus when He will return to earth. That will be the Day of Atonement for the Jewish remnant when they "look upon Him whom they have pierced," repent of their sins, and receive Him as their Messiah (
Zechariah 12:10 and
Romans 11:1-6,
25-36).
7)
Tabernacles or Booths (
Leviticus 23:34) – Many scholars believe that this feast day points to the Lord’s promise that He will once again “tabernacle” with His people when He returns to reign over all the world (
Micah 4:1-7).
