There are multiple events...
The rapture - In ordinary times, such as Lots and Noahs.
The kingdom of the AntiChrist - 3.5 years
The tribulation - 3.5 years - The plagues
The second coming of the Lord Jesus Christ - Between the tribulation and the millennial reign
The rapture happens in ordinary times. If this event were post tribulation it would be rather well announced, and not as a thief in the night...
26 And as it was in the days of Noe, so shall it be also in the days of the Son of man.
27 They did eat, they drank, they married wives, they were given in marriage, until the day that Noah entered into the ark, and the flood came, and destroyed them all.
28 Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded;
29 But the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed them all.
30 Even thus shall it be in the day when the Son of man is revealed. - Luke 19
Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; -
2 Thessalonians 2:3
The Return of Christ comes after tribulation.
26 And then shall they see the Son of man coming in the clouds with great power and glory.
27 And then shall he send his angels, and shall gather together his elect from the four winds, from the uttermost part of the earth to the uttermost part of heaven. - Mark 13
