They leave out another important detail however.Yom Teruah is the only festival that no man knows when exactly it will occur. This is due to the fact that it begins on the new moon. The new moon was sanctified when two witnesses see the new moon and attest to it before the Sanhedrin in the Temple.This sanctification could happen during either of two days, depending on when the witnesses come. Since no one knew when the witnesses would come, no one knew when the Feast of Trumpets would start.On the 30th of each month, the members of the High Court assembled in a courtyard in Jerusalem, where they waited to receive the testimony of two reliable witnesses. They then sanctified the new moon. The new moon is very difficult to see on the first day because it can be seen only about sunset, close to the sun, when the sun is traveling north. So, looking for a very slim faint crescent moon, which is very close to the sun, is a very difficult thing to do. If the moon’s crescent was not seen on the 30th day, the new moon was automatically celebrated on the 31st day.
After the witnesses are interviewed, to confirm that they are indeed two agreeing witnesses, the High Priest was informed. Then The High Priest stood at the top of the Temple Mount (because the witnesses brought this news to the bottom of the mount) and tells the two witnesses to "Come up" and they ascend the Temple Mount to the High Priest, and then they sound the Last Trump.
This site's argument against tying this to the Seventh Trumpet was.
We cannot go to the Book of Revelation and say that the voice of the seventh angel (Revelation 11:15) is the last trump. In the first century, the last trump (shofar) meant a specific day in the year.It's not an argument, people are just under the assumption Yom Teruah and the 7th Trumpet can't be the same cause we are conditioned to think the Fall Feast begin/end years even though Biblically they mark the middle. So we're not prepared to see them in the middle of Revelation unless you're a post-tirbber who garbles the chronology.
This site also talks about how Jewish thought also has a First Trumpet, and the First Trumpet is sounded on Pentecost.
Well I've argued on this Blog extensively why I see the Sixth Seal and Revelation 7 as the second fulfillment of Joel 2:28-32. And the sealing of the 144,000 is the latter rain, the final great outpouring of the Holy Spirit. So the First Trumpet being sounded right after that fits perfectly.
This site assumes the Great Trumpet and Last Trumpet can't be the same simply because Rabbinic Tradition distinguishes them I guess.
I believe when The Witnesses are Resurrected will be when the sliver of the New Moon of Tishri is seen. The World will witnesses their rising, they'll preach some more, The Gospel will spread and then God will call them up to Heaven and they will Ascend to Heaven.
Then the people of Jerusalem (who we know from the beginning of chapter 11 are mostly Gentiles at this time) will Believe and Repent and Praise God. That will be when the fullness of the Gentiles is come in. Then the Seventh Trumpet is sounded.
Jesus said in Luke 21 that Jerusalem will be "Trodden under foot of the Gentiles till the Times of the Gentiles are fulfilled". And that is when he will return.
