Can you show me a verse that says the tribulation is 7 years? From my reading, Jesus said the tribulation would begin when the sacrifice was stopped and would end with his coming.
This is the verse that initially specifies the final 7 year period:
DAN9:27 And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate.

This is the period Jesus refers to in the Olivet Discourse :
MAT24:14 And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come. MAT24:15 When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand:) MAT24:16 Then let them which be in Judaea flee into the mountains: MAT24:17 Let him which is on the housetop not come down to take any thing out of his house: MAT24:18 Neither let him which is in the field return back to take his clothes.

Hope that helps.
