One thing that's interesting is he has put together a lot of work on the Feasts of the LORD as described in Leviticus 23. https://www.biblegateway.com/passage/?search=Leviticus+23&version=NKJV

The short version is that these feasts are being fulfilled as bible prophecy. The first 4 were fulfilled when Jesus came the first time, and the next one to be fulfilled will be the Feast of Trumpets. That occurs every year in the fall in September. Scottie doesn't like setting dates, but there is excitement every year around that time as the anticipation of the rapture. I'd say, because this revelation 12 sign occurs (not coincidentally ) the exact day of the feast of trumpets this year, there's way more excitement.

So to answer your question, he has predicted that the rapture would occur on the feast of trumpets on some year, and there's a lot pointing to this year.
