The 7th Trumpet we are shown in Revelation 10, that when it sounds, all Bible prophecy for this present world will be finished.
Rev 10:7
7 But in the days of the voice of the seventh angel, when he shall begin to sound, the mystery of God should be finished, as He hath declared to His servants the prophets.
KJV
That means all the final events written of in Revelation 11 about the 7th Trumpet - 3rd Woe Period happen AT THE SAME TIME, on the same day, in the same hour even. That means all... of the following events...
Rev 11:14-19
14 The second woe is past; and, behold, the third woe cometh quickly.
15 And the seventh angel sounded; and there were great voices in heaven, saying, "The kingdoms of this world are become the kingdoms of our Lord, and of His Christ; and He shall reign for ever and ever."
16 And the four and twenty elders, which sat before God on their seats, fell upon their faces, and worshipped God,
17 Saying, "We give Thee thanks, O Lord God Almighty, Which art, and wast, and art to come; because Thou hast taken to Thee Thy great power, and hast reigned."
18 And the nations were angry, and Thy wrath is come, and the time of the dead, that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear Thy name, small and great; and shouldest destroy them which destroy the earth.
19 And the temple of God was opened in heaven, and there was seen in His temple the ark of His testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.
KJV
Notice on that 7th Trumpet - 3rd Woe Period is the time of God's "wrath" with that "Thy wrath is come", and it it is time with... the resurrection, i.e., the "time of the dead". That WRATH is the final wrath of the 7th Vial spoken of in Revelation 16, and on the 6th Seal.
So what I've been trying to get you to understand, is how each of the last three Trumpet-Woe periods have EVENTS that occur within each one. And the succeeding next Woe does not occur until all the EVENTS given within the specific Trumpet-Woe period are completed.
Furthermore, that God's final cup of WRATH occurs at "the time of the dead", i.e., the resurrection when Jesus returns, that points to the 6th Seal timing, the 7th Vial timing, and the 7th Trumpet timing. The 7th Seal is a type of 'selah' rest. So the wrath mentioned on the 6th Seal actually is represented by the final 7th Seal also. Jesus simply used the 7th Seal as a transition only. Thus Jesus comes on 7,7,7. Satan as the false-Messiah comes on 6,6,6.
