When the tribulation period begins, there will be much debate whether it has started or not. God has provided a secondary sign (a sign which will confirm the tribulation period has started) which will take place 255 days after the tribulation period begins. This sign is found in the vision of the two horned ram by Daniel. The details are found in the following verses.Dan 8: 13 Then I heard a holy one speaking, and another holy one said to him, "How long will it take for the vision to be fulfilled—the vision concerning the daily sacrifice, the rebellion that causes desolation, and the surrender of the sanctuary and of the host that will be trampled underfoot?" 14 He said to me, "It will take 2,300 evenings and mornings; then the sanctuary will be reconsecrated."If you review the entire chapter of Daniel 8 you will see that events transpire as follows:1. The A/C downs “starry host” and tramples them underfoot2. The A/C desecrates the temples (the daily sacrifice, the rebellion that causes desolation, and the surrender of the sanctuary)3. The sanctuary(Temple) is reconsecrated....for a duration of 2300 days.According to the OT, the temple mount, if desecrated must be reconsecrated before sacrifices and worship can be started. At some time when the yet-to-be built Temple is being built the mount will have to be reconsecrated because it has been defiled for centuries. The minute the A/C steps in the holy place and proclaims himself God, the temple will again be defiled and will remain desecrated until the advent of Christ where Christ the High Priest will reconsecrate the mount again.This reconsecration of the sanctuary by Christ provides us with an endpoint of this 2300 day vision. And we know that the A/C will desecrate the temple 1263 ½ days before the advent of Christ. The significance of this vision is that the A/C will down “starry host” 2300 days before TDOL. And both the tribulation period and this vision of the 2300 days both end with TDOL.The tribulation period is supposed to be seven years in duration. 7 x 365 = 2555If you subtract 2300 days from the 2555 you have a difference of 255 days. So, if the tribulation period is seven years in duration then the “starry host” will be downed by the A/C 255 days after the start of the tribulation period. What or who the “starry host” are is a whole different topic.In Yehoshua,Guy Smith
