What is the tribulation? How long is it?
The tribulation is a seven-year period of God's judgment on the earth and discipline of Israel, the seventieth week of Daniel 9, culminating in the return of Christ. Jesus called its second half "great tribulation, such as was not since the beginning of the world" (Matt 24:21).
What the text states
Daniel 9:24-27 measures "seventy weeks" (seventy sevens of years) on Israel; sixty-nine ran to the Messiah, and one remains, a seven-year period begun when the coming prince "confirm[s] the covenant with many for one week" (9:27). At its midpoint he breaks it and the great tribulation begins. Revelation 6-19 details the seals, trumpets, and vials of that period. It is "the time of Jacob's trouble" (Jer 30:7), aimed at bringing Israel to her Messiah, and it ends when "they shall look upon me whom they have pierced" (Zech 12:10).
Preterism holds the tribulation was fulfilled in AD 70 (see the Josephus section). Historicism spreads it across church history. We hold it is future, a literal seven years, because Daniel's seventy weeks are measured on Israel and the events of Revelation 6-19 (a third of mankind dead, the sun darkened, the sea turned to blood) have no historical fulfillment.
