Yes, when you say the battle of Armageddon has nothing to do with Christ's 2nd coming, when the Revelation 16 Scriptures shows it does, then what you said is exactly that, silly confusion.
I'm pretty sure I've already covered that 42 months idea in this thread, but here it is again in case you're hard of hearing...
Per Revelation 13, Satan as the "dragon" is given 42 months to reign over all nations and make war with the saints and overcome them. In Revelation 11, the 42 months is linked with events in Jerusalem involving the time of God's two witnesses prophesying for 1260 days. The 42 months and 1260 days is equal to the "time and times and dividing of time" of Daniel 7:25, the latter three and half years of Daniel's final "one week" prophecy in Daniel 9. It represents the time of "great tribulation" for the end of this world just PRIOR to Christ's 2nd coming.
Revelation 11 is covering events to happen on the 6th and 7th Trumpets. Christ's 2nd coming is on the 7th Trumpet, which are the same events of the 7th Vial.
Close but not quite there.
The 6th Seal happens before the 7th Seal. The 7th Seal happens before the 1st Trumpet. The Trumpets cover time spent by the Lamb on the earth since the 6th Seal. That is the Second Coming of the final harvest. That is the end of the 7 weeks mentioned by Daniel.
If there is any one left after the Trumpets and Thunders, then and only then does Satan get control of the vineyard to turn it into his followers who will then be marked by God, and removed from the Lamb's book of life. The battle of Armageddon is when Jesus Christ kills all who are left on earth.
If Satan does not get 42 months, then chapter 14 is the completion of the wine press and any one left will be destroyed. No time for Satan, no vials, and no battle of Armageddon.
The Second Coming is a harvest, and the sheep, goats, wheat, and tares are dealt with before the 7th Trumpet brings the harvest to a close.
It is in the midst of the week of the 7th Trumpet, that Satan may get an additional 42 month extension in the vineyard. The Second Coming has already happened and the final work of Jesus Christ on earth is signified as finished with the days of the sound from the 7th Trumpet.
5 Then the angel I saw standing on the sea and on the land
lifted his right hand toward heaven
6 and swore by the One who lives forever and ever,
who created heaven and what is in it, earth and what is in it, and the sea and what is in it: “There will be no more delay;
7 on the contrary, in the days of the sound from the seventh angel when he sounds his
shofar, the hidden plan of God will be brought to completion, the Good News as he proclaimed it to his servants the prophets.”
John sees this angel before the 7th Trumpet just after this:
He planted his right foot on the sea and his left foot on the land,
3 and shouted in a voice as loud as the roar of a lion; and when he shouted, seven thunderclaps sounded with voices that spoke.
4 When the seven thunders spoke, I was about to write; but I heard a voice from heaven say,
“Seal up the things the seven thunders said,
do not write them down!”
Between the 6th and 7th Trumpets are 7 Thunders. They have to happen as well, but we are not given any information about them. So trying to lump all the 6's and 7's together cannot work. The Seals happen, then the Lamb and the 144k are on earth. The Trumpets 1-6 happen. Then 7 Thunders happen. Then and only then can the 7th Trumpet sound.
If Satan gets 42 months, the 7th Trumpet stops only after the 7 vials, and the one hour battle of Armageddon. Then the 7th Trumpet stops and all is complete from Daniel 9:24-27
"putting an end to the transgression, for making an end of sin, for forgiving iniquity, for bringing in everlasting justice, for setting the seal on vision and prophet, and for anointing the Especially Holy Place"
The 7th Trumpet is the week of confirmation.
"the hidden plan of God will be brought to completion, the Good News as he proclaimed it to his servants the prophets.”
Daniel 9:27 will be fulfilled at the end of the 7th Trumpet. Either by the wine press of Revelation 14 or the Armageddon of Revelation 19. Both will be the completion of the 7th Trumpet.
