Here is my take on the Revelation Timeline:

1. Seals 1,2,3,4,5 begun at Pentecost (Preaching of the Gospel continued on; Wars continued on; Economic woes and hunger continued on; death from wars, famine, plagues, and wild beasts continued on; deaths and martyrdom of christians continued on)
2. Seal 6 is at the end of the Great Tribulation, start of God's Wrath (Bowls Judgement), Resurrection of the Dead in Christ and Rapture of the still Alive prior to Armageddon and Second Coming of Christ
3. Seal 7 is the start of the Millennium
4. Half Hour Silence in heaven is the millennium, the thousand year of peace
5. Trumpets 1, 2, 3, 4, starts at the end of the millennium (all the plagues are executed by the Two Witnesses)
6. Trumpet 5 started when Satan was released from the Abyss (Keyword is Abyss, and those who does not have the Seal of God which could have been said another way also as those who have the mark of the beast, but it did not, because the mark of the beast happens prior to Second Coming of Christ)
7. Trumpet 6 started when the nations were deceived to fight against the people of God at the Mountain/Temple of Jerusalem, Gog and Magog. (Ezekiel 38; Unwalled City, Living in Peace, Recovered from War; Ezekiel 39 is Armageddon War, Great Supper for the Birds)
8. The Angel and the Little Scroll (Different from the Scroll and the Lamb), and the ministry of the Two Witnesses started at the end of the millennium and ends after 42 months.
9. Trumpet 7 is pouring of God's Wrath (Heaven and Earth melted from Fire) to the nations and after that, the Great White Throne Judgement, for it mentioned that the time has come for judging the dead (this did not happen at the first resurrection because in Rev. 20 it said, the rest of the dead did not come to life until the thousand years were ended)
