I don't have a lot of band width due to storms in our area so I'll be brief and try to comment more later. I'll agree with @Scarecrow on pretty much everything except the seventh trump. The passage in 1 Thess 5 dealing with the last trump is a specific reference to a mow'ed (a divinely appointed day) and is a Jewish idiom for feast of trumpets and the 100th blast as is the reference to no man knows the day nor the hour. It is coincidental only regarding the 7th trumpet judgement.
Additional info to think about. If the two witnesses killed in Rev 11 are part of the 144000, they are sealed and commissioned in Rev 7 (6th seal), preach for 3 1/2 years before being killed by Apollyon Rev 11 (who first appears as part of the 5th trumpet Rev 9 ) then the false prophet and dragon try to exterminate the Jews for another 3 1/2 years (Rev 12:6) ending at Armageddon.
To check my math, count back from Armageddon. "A" Day -- 3 1/2 yrs = Anti C in temple & death of 2 Witnesses. -- 2 Guys preaching for 3 1/2 yrs from commission = 6th seal thus 7 years between 6th Seal and Armageddon. If true, everything pre 6th Seal is tribulation, 6th Seal is Great Tribulation just as Matt 24 states, including the "episynagoge" after great T. And everything else is 7 years of wrath/great wrath till Armageddon beginning with the 1st mention of Judgement occurring which is the 1st Trumpet Judgement. (The actual first mention is in the 5th Seal but it states that judgement is being held in check and hasn't started yet)
Also compare the angels holding back the four winds Rev 7 from hurting the earth, sea and trees, with the first 4 Trumpet Judgements. Trumpets can't begin till the seals are done, unlike the first 5 bowls which begin after the 5th T Judgement and the 6th and 7th Bowls and Trumpets are interdependent.
When we have wifi back I'll try to post a chart I've been working on showing this timeline
