This below proves who it is that is in a circular-loop with their thinking, certainly not me...
6th Trumpet - 2nd Woe Timing (i.e., the tribulation):
Rev 11:2-3
2 But the court which is without the temple leave out, and measure it not; for it is given unto the Gentiles: and the holy city shall they tread under foot forty and two months.
3 And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth.
KJV
That 42 months is per a lunar time reckoning, and the 1260 days is per a solar time reckoning. The 42 months per the lunar is about the children of darkness. The 1260 days per the solar is for the children of the day. That 42 months or 1260 days is equal to HALF of Daniel's symbolic "one week" (7 YEARS).
The Dragon's Reign:
Rev 13:4-7
4 And they worshipped the dragon which gave power unto the beast: and they worshipped the beast, saying, Who is like unto the beast? who is able to make war with him?
5 And there was given unto him a mouth speaking great things and blasphemies; and power was given unto him to continue forty and two months.
6 And he opened his mouth in blasphemy against God, to blaspheme His name, and His tabernacle, and them that dwell in heaven.
7 And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations.
KJV
That is directly linked to the events in the Book of Daniel about the end, and also the Revelation 11 events of the 6th Trumpet - 2nd Woe period. The 6th Trumpet - 2nd Woe period began in Revelation 9:12 with the loosing of the four angels bound at the river Euphrates. It symbolizes the time of 'great tribulation" at the end of this world just prior to Christ's return.
