Once the great tribulation starts with the setting up of the AoD, abomination of desolation, statue image of the beast-king, in Revelation 8, the seventh seal is removed and trumpet judgments of God begin.
1 And when he had opened the seventh seal, there was silence in heaven about the space of half an hour.
There are four angels sounding their trumpets to announce the first four judgments. Then there are three angels remaining to sound, which those announce 3 Woe to the inhabiters of the earth.
Two of the Woes are in Revelation 9, what they will be. The third woe, announced when the seventh angel sounds, is Satan cast down to the earth, having a time, times, half time left, in Revelation 12:12
The first two woes fit within that time, times, half time.
12 Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.
