Prewrath
According to prewrath, this passage clearly indicates that the coming of the Lord and the Day of the Lord are part and parcel of the same event, the coming of the Lord. First, Jesus arrives in the sky at His Second Coming, at which time He raptures all Christian believers, then His judgment during the Day of the Lord falls upon those who have disbelieved and rejected His lordship.
This is justified, according to prewrath, by the fact that Jesus places His return (Matthew 24:30–31) after the abomination of desolation (Matthew 24:15), which occurs at the midpoint of the 70th Week (cf. Daniel 9:27, Daniel 11:31). Thus, if the Second Coming and rapture occur after the sixth seal, this places this event after the midpoint but before the end (seventh trumpet).
Chronology of Jesus
Two main approaches have been used to estimate the year of the birth of Jesus: one based on the accounts in the Gospels of his birth with reference to King Herod's reign, and the other by subtracting his stated age of "about 30 years" when he began preaching. Most scholars, on this basis, assume a date of birth between 6 and 4 BC.
